+------------------------------------------------------------------------ + +Sometimes, daughterboards will require modification +to work on certain frequencies or to work with certain hardware.

different clocking capabilities, +the DBSRX will require modifications to operate on a non-USRP1 motherboard. +On a USRP1 motherboard, a divided clock is provided from an FPGA pin +because the standard daughterboard clock lines cannot provided a divided clock. +However, on other USRP motherboards, the divided clock is provided +over the standard daughterboard clock lines. + +**Step 1: Move the clock configuration resistor** + +Remove R193 (which is 10 ohms, 0603 size) and put it on R194, which is empty. +This is made somewhat more complicated by the fact that the silkscreen is not clear in that area. +R193 is on the back, immediately below the large beige connector, J2. +R194 is just below, and to the left of R193. +The silkscreen for R193 is ok, but for R194, +it is upside down, and partially cut off. +If you lose R193, you can use anything from 0 to 10 ohms there. + +**Step 2: Burn a new daughterboard id into the EEPROM** + +With the daughterboard plugged-in, run the following commands: +:: + + cd <install-path>/share/uhd/utils + ./usrp_burn_db_eeprom --id=0x000d --unit=RX --args=<args> --slot=<slot> + +* <args> are device address arguments (optional if only one USRP is on

+------------------------------------------------------------------------ + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Two-stage tuning process +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +A USRP device has two stages of tuning: + +* RF front-end: translates bewteen RF and IF +* DSP: translates between IF and baseband + +In a typical use-case, the user specifies an overall center frequency for the +signal chain. The RF front-end will be tuned as close as possible to the center +frequency, and the DSP will account for the error in tuning between target +frequency and actual frequency. The user may also explicitly control both +stages of tuning through through the tune_request_t object, which allows for +more advanced tuning. + +In general, Using UHD's advanced tuning is highly recommended as it makes it +easy to move the DC component out of your band-of-interest. This can be done by +passing your desired LO offset to the tune_request_t object, and letting UHD +handle the rest. + +Tuning the receive chain: +:: + + //tuning to a desired center frequency + usrp->set_rx_freq(target_frequency_in_hz); + + --OR-- + + //advanced tuning with tune_request_t + uhd::tune_request_t tune_req(target_frequency_in_hz, desired_lo_offset); + //fill in any additional/optional tune request fields... + usrp->set_rx_freq(tune_req); + +More information can be fonud in *tune_request.hpp*. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +RF front-end settling time +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +After tuning, the RF front-end will need time to settle into a usable state. +Typically, this means that the local oscillators must be given time to lock +before streaming begins. Lock time is not consistent; it varies depending upon +the device and requested settings. After tuning and before streaming, the user +should wait for the "lo_locked" sensor to become true, or sleep for +a conservative amount of time (perhaps a second). + +Pseudo-code for dealing with settling time after tuning on receive: +:: + + usrp->set_rx_freq(...); + sleep(1); + usrp->issue_stream_command(...); + + --OR-- + + usrp->set_rx_freq(...); + while (not usrp->get_rx_sensor("lo_locked").to_bool()){ + //sleep for a short time in milliseconds + } + usrp->issue_stream_command(...); + +------------------------------------------------------------------------ +Specifying the subdevice to use +------------------------------------------------------------------------ +A subdevice specification string for USRP family devices is composed of: + +:: + + <motherboard slot name>:<daughterboard frontend name> + +Ex: The subdev spec markup string to select a WBX on slot B. + +:: + + B:0 + +Ex: The subdev spec markup string to select a BasicRX on slot B. + +:: + + B:AB + + -- OR -- + + B:A + + -- OR -- + + B:B + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +USRP Family Motherboard Slot Names +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +All USRP family motherboards have a first slot named **A:**. The USRP1 has +two daughterboard subdevice slots, known as **A:** and **B:**. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Daughterboard Frontend Names +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Daughterboard frontend names can be used to specify which signal path is used +from a daughterboard. Most daughterboards have only one frontend **:0**. A few +daughterboards (Basic, LF and TVRX2) have multiple frontend names available. +The frontend names are documented in the +`Daughterboard Application Notes <./dboards.html>`_ + +------------------------------------------------------------------------ +Overflow/Underflow notes +------------------------------------------------------------------------ +**Note:** The following overflow/underflow notes do not apply to USRP1, +which does not support the advanced features available in newer products. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Overflow notes +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +When receiving, the device produces samples at a constant rate. +Overflows occurs when the host does not consume data fast enough. +When UHD detects the overflow, it prints an "O" to stdout, +and pushes an inline message packet into the receive stream. + +**Network-based devices**: +The host does not back-pressure the receive stream. +When the kernel's socket buffer becomes full, it will drop subsequent packets. +UHD detects the overflow as a discontinuity in the packet's sequence numbers, +and muxes an inline message packet into the receive stream. + +**Other devices**: +The host back-pressures the receive stream. +Therefore, overflows always occur in the device itself. +When the device's internal buffers become full, streaming is shutoff, +and an inline message packet is sent to the host. +If the device was in continuous streaming mode, +the UHD will automatically restart streaming. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Underflow notes +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +When transmitting, the device consumes samples at a constant rate. +Underflow occurs when the host does not produce data fast enough. +When the UHD detects underflow, it prints an "U" to stdout, +and pushes a message packet into the async message stream. + +------------------------------------------------------------------------ +Threading notes +------------------------------------------------------------------------ + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Thread safety notes +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +For the most part, UHD is thread-safe. +Please observe the following limitations: + +**Fast-path thread requirements:** +There are three fast-path methods for a device: send(), recv(), and recv_async_msg(). +All three methods are thread-safe and can be called from different thread contexts. +For performance, the user should call each method from a separate thread context. +These methods can also be used in a non-blocking fashion by using a timeout of zero. + +**Slow-path thread requirements:** +It is safe to change multiple settings simultaneously. However, +this could leave the settings for a device in an uncertain state. +The is because changing one setting could have an impact on how a call affects other settings. +Example: setting the channel mapping affects how the antennas are set. +It is recommended to use at most one thread context for manipulating device settings. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Thread priority scheduling +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +When the UHD spawns a new thread it may try to boost the thread's scheduling priority. +When setting the priority fails, the UHD prints out an error. +This error is harmless, it simply means that the thread will have a normal scheduling priority. + +**Linux Notes:** + +Non-privileged users need special permission to change the scheduling priority. +Add the following line to */etc/security/limits.conf*: +:: + + @<my_group> - rtprio 99 + +Replace <my_group> with a group to which your user belongs. +Settings will not take effect until the user has logged in and out. + +------------------------------------------------------------------------ +Misc notes +------------------------------------------------------------------------ + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Support for dynamically loadable modules +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +For a module to be loaded at runtime, it must be: + +* found in the UHD_MODULE_PATH environment variable, +* installed into the <install-path>/share/uhd/modules directory, +* or installed into /usr/share/uhd/modules directory (unix only). + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Disabling or redirecting prints to stdout +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +The user can disable the UHD library from printing directly to stdout by registering a custom message handler. +The handler will intercept all messages, which can be dropped or redirected. +Only one handler can be registered at a time. +Make "register_handler" your first call into UHD: + +:: + + #include <uhd/utils/msg.hpp> + + void my_handler(uhd::msg::type_t type, const std::string &msg){ + //handle the message... + } + + uhd::msg::register_handler(&my_handler); diff --git a/host/docs/gpsdo.rst b/host/docs/gpsdo.rst new file mode 100644 index 000000000..f732aae63 --- /dev/null +++ b/host/docs/gpsdo.rst @@ -0,0 +1,80 @@ +======================================================================== +UHD - Internal GPSDO Application Notes +======================================================================== + +.. contents:: Table of Contents + +This application note describes the use of integrated GPS-disciplined +oscillators with Ettus Research USRP devices.

parameters +into the underlying transport layer through the device address. +These optional parameters control how the transport object allocates memory, +resizes kernel buffers, spawns threads, etc. +When not spcified, the transport layer will use values for these parameters +that are known to perform well on a variety of systems. +The transport parameters are defined below for the various

+The UDP transport is implemented with user-space sockets. +This means standard Berkeley sockets API using send()/recv(). + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Transport parameters +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +The following parameters can be used to alter the transport's default behavior: + +* **recv_frame_size:** The size of a single receive buffer in bytes +* **num_recv_frames:** The number of receive buffers to allocate +* **send_frame_size:** The size of a single send buffer in bytes +* **num_send_frames:** The number of send buffers to allocate +

decrease the maximum number of samples per packet. +The frame sizes default to an MTU of 1472 bytes per IP/UDP packet, +and may be increased if permitted by your network hardware. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Flow control parameters +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +The host-based flow control expects periodic update packets from the device. +These update packets inform the host of the last packet consumed by the device, +which allows the host to determine throttling conditions for the transmission of packets. +The following mechanisms affect the transmission of periodic update packets: + +* **ups_per_fifo:** The number of update packets for each FIFO's worth of bytes sent into the device +* **ups_per_sec:** The number of update packets per second (defaults to 20 updates per second) + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Resize socket buffers +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +It may be useful increase the size of the socket buffers to +move the burden of buffering samples into the kernel, or to +buffer incoming samples faster than they can be processed. +However, if your application cannot process samples fast enough, +no amount of buffering can save you. +The following parameters can be used to alter socket's buffer sizes: + +* **recv_buff_size:** The desired size of the receive buffer in bytes +* **send_buff_size:** The desired size of the send buffer in bytes + +**Note:** Large send buffers tend to decrease transmit performance. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Latency Optimization +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Latency is a measurement of the time it takes a sample to travel between the host and device. +Most computer hardware and software is bandwidth optimized which may negatively affect latency. +If your application has strict latency requirements, please consider the following notes: + +**Note1:** +The time taken by the device to populate a packet is proportional to the sample rate. +Therefore, to improve receive latency, configure the transport for a smaller frame size. + +**Note2:** +For overall latency improvements, +look for "Interrupt Coalescing" settings for your OS and ethernet chipset. +It seems the Intel ethernet chipsets offer fine-grained control in Linux. +Also, consult: + +*

An address of **192.168.10.1** and a subnet +mask of **255.255.255.0** is recommended. + +On a Linux system, you can set a static IP address very easily by using the +'ifconfig' command: +:: + + sudo ifconfig <interface> 192.168.10.1 + +Note that <interface> is usually something like 'eth0'. You can discover the +names of the network interfaces in your computer by running 'ifconfig' without +any parameters: +:: + + ifconfig -a + +**Note:** +When using the UHD, if an IP address for the USRP2 is not specified, +the software will use UDP broadcast packets to locate the USRP2. +On some systems, the firewall will block UDP broadcast packets. +It is recommended that you change or disable your firewall settings. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Multiple devices per host +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +For maximum throughput, one ethernet interface per USRP2 is recommended, +although multiple devices may be connected via a gigabit ethernet switch. +In any case, each ethernet interface should have its own subnet, +and the corresponding USRP2 device should be assigned an address in that subnet. +Example: + +**Configuration for USRP2 device 0:** + +* Ethernet interface IPv4 address: 192.168.10.1 +* Ethernet interface subnet mask: 255.255.255.0 +* USRP2 device IPv4 address: 192.168.10.2 + +**Configuration for USRP2 device 1:** + +* Ethernet interface IPv4 address: 192.168.20.1 +* Ethernet interface subnet mask: 255.255.255.0 +* USRP2 device IPv4 address: 192.168.20.2 + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Change the USRP2's IP address +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +You may need to change the USRP2's IP address for several reasons: + +* to satisfy your particular network configuration +* to use multiple USRP2s on the same host computer +* to set a known IP address into USRP2 (in case you forgot) + +**Method 1:** +To change the USRP2's IP address +you must know the current address of the USRP2, +and the network must be setup properly as described above. +Run the following commands: +:: + + cd <install-path>/share/uhd/utils + ./usrp_burn_mb_eeprom --args=<optional device args> --key=ip-addr --val=192.168.10.3 + +**Method 2 (Linux Only):** +This method assumes that you do not know the IP address of your USRP2. +It uses raw ethernet packets to bypass the IP/UDP layer to communicate with the USRP2. +Run the following commands: +:: + + cd <install-path>/share/uhd/utils + sudo ./usrp2_recovery.py --ifc=eth0 --new-ip=192.168.10.3 + +------------------------------------------------------------------------ +Communication problems +------------------------------------------------------------------------ +When setting up a development machine for the first time, +you may have various difficulties communicating with the USRP device. +The following tips are designed to help narrow-down and diagnose the problem. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +RuntimeError: no control response +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +This is a common error that occurs when you have set the subnet of your network +interface to a different subnet than the network interface of the USRP. For +example, if your network interface is set to 192.168.20.1, and the USRP is +192.168.10.2 (note the difference in the third numbers of the IP addresses), you +will likely see a 'no control response' error message. + +Fixing this is simple - just set the your host PC's IP address to the same +subnet as your USRP. Instructions for setting your IP address are in the +previous section of this documentation. + + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Firewall issues +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +When the IP address is not specified, +the device discovery sends broadcast UDP packets from each ethernet interface. +Many firewalls will block the replies to these broadcast packets. +If disabling your system's firewall, +or specifying the IP address yeilds a discovered device, +then your firewall may be blocking replies to UDP broadcast packets. +If this is the case, we recommend that you disable the firewall, +or create a rule to allow all incoming packets with UDP source port 49152. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Ping the device +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +The USRP will reply to icmp echo requests. +A successful ping response means that the device has booted properly, +and that it is using the expected IP address. + +:: + + ping 192.168.10.2 + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Monitor the serial output +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Read the serial port to get debug verbose from the embedded microcontroller. +The microcontroller prints useful information about IP addresses, +MAC addresses, control packets, fast-path settings, and bootloading. +Use a standard USB to 3.3v-level serial converter at 230400 baud. +Connect GND to the converter ground, and connect TXD to the converter receive. +The RXD pin can be left unconnected as this is only a one-way communication. + +* **USRP2:** Serial port located on the rear edge +* **N210:** Serial port located on the left side + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Monitor the host network traffic +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Use wireshark to monitor packets sent to and received from the device. + +------------------------------------------------------------------------ +Addressing the device +------------------------------------------------------------------------ + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Single device configuration +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In a single-device configuration, +the USRP device must have a unique IPv4 address on the host computer. +The USRP can be identified through its IPv4 address, resolvable hostname, or by other means. +See the application notes on `device identification <./identification.html>`_. +Use this addressing scheme with the *single_usrp* interface. + +Example device address string representation for a USRP2 with IPv4 address 192.168.10.2 + +:: + + addr=192.168.10.2 + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Multiple device configuration +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In a multi-device configuration, +each USRP device must have a unique IPv4 address on the host computer. +The device address parameter keys must be suffixed with the device index. +Each parameter key should be of the format <key><index>. +Use this addressing scheme with the *multi_usrp* interface. + +* The order in which devices are indexed corresponds to the indexing of the transmit and receive channels. +* The key indexing provides the same granularity of device identification as in the single device case. + +Example device address string representation for 2 USRP2s with IPv4 addresses 192.168.10.2 and 192.168.20.2 +:: + + addr0=192.168.10.2, addr1=192.168.20.2 + +------------------------------------------------------------------------ +Using the MIMO Cable +------------------------------------------------------------------------ +The MIMO cable allows two USRP devices to share reference clocks, +time synchronization, and the ethernet interface. +One of the devices will sink its clock and time references to the MIMO cable. +This device will be referred to as the slave, and the other device, the master. + +* The slave device acquires the clock and time references from the master device. +* The master and slave may be used individually or in a multi-device configuration. +* External clocking is optional, and should only be supplied to the master device. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Shared ethernet mode +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In shared ethernet mode, +only one device in the configuration can be attached to the ethernet. + +* Clock reference, time reference, and data are communicated over the MIMO cable. +* Both master and slave must have different IPv4 addresses in the same subnet. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Dual ethernet mode +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In dual ethernet mode, +both devices in the configuration must be attached to the ethernet. + +* Only clock reference and time reference are communicated over the MIMO cable. +* Both master and slave must have different IPv4 addresses in different subnets. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Configuring the slave +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In order for the slave to synchronize to the master over MIMO cable, +the following clock configuration must be set on the slave device: +:: + + uhd::clock_config_t clock_config; + clock_config.ref_source = uhd::clock_config_t::REF_MIMO; + clock_config.pps_source = uhd::clock_config_t::PPS_MIMO; + usrp->set_clock_config(clock_config, slave_index); + +------------------------------------------------------------------------ +Hardware setup notes +------------------------------------------------------------------------ +
