| * Fix off-by-one errorJonathan Wakely2016-06-071-1/+1
| | | | | | | | There's an off-by-one error in base64_decode_value that results in undefined behaviour when it's passed `'\x7b'`
* | Added the option to disable ADC self-testMarcus Müller2016-06-061-1/+1
| | | | | | | | | | | | This proved helpful on devices where the EEPROM is wrong about hardware revision, and the EEPROM writing doesn't work, because the ADC self-test fails due to being run for the wrong board revision.

| * UBX: Fixed noise issues and reduced power consumption and heatmichael-west2016-05-261-23/+37
| | | | | | | | | | - Removed force on of components to reduce noise, power consumption, and heat - Set TX PA force on only when RX antenna set to RX2 to remove long TX transient caused by HW issue on TX path

| * bugfix#1102: Prevented X300 DAC FIFO from underflowingAshish Chaudhari2016-05-253-15/+4
| | | | | | | | | | | | | | - The spectral distortion was begin caused by the DAC FIFO underflowing. The fix was to run through the DAC sync procedure which uses the falling edge clock to sample the RefClk and sync it with the data clk
* | x300: Fixed an issue where the wrong XB port was being selectedPaul David2016-05-191-18/+43
| | | | | | | | | | | | - If there were duplicate IPs in the mboard eeprom, the last one would be selected instead of the first - The default IP addresses (used for the case where the mboard eeprom can't be read) would overwrite the previous settings - Added a warning for duplicate IP entries in the mboard eeprom
* | x300: Check the maximum frame size for both linksPaul David2016-05-181-1/+22
| | | | | | | | | | - This change ensures that the smallest frame size is chosen with dual ethernet - It helps avoid any issues with using frame sizes larger than what the smaller link supports
* | dboard_iface: Added FE name input to set_fe_connectionAshish Chaudhari2016-05-165-15/+21
| | | | | | | | | | - A dboard_base class can have multiple frontends (subdevs) and the set_fe_connection needs to be able to distinguish between them
* | x300: Fixed false link capacity warning and cleaned up some codePaul David2016-05-132-11/+7
| | | | | | | | | | - Fixed an issue where 10GE on the HGS image presented a false warning for the link capacity - Removed some unnecessary variables after cleanup

| | | | | | | | | | | | | | DSP rates are now being tracked as in whether or not they've been set. We can disregard unset DSPs for the automatic clock rate calculation. Reviewed-By: Derek Kozel <derek.kozel@ettus.com>

| * e3xx: spi: Fix issue introduced in 1b149f56Moritz Fischer2016-04-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernels (3.15+) introduce the possibility to do DUAL and QUAD spi operations via spidev. Prior to this commit nothing was setting the {tx,rx}_nbits members of the struct spi_ioc_transfer. from include/uapi/linux/spi/spidev.h struct spi_ioc_transfer { __u64 tx_buf; __u64 rx_buf; __u32 len; __u32 speed_hz; __u16 delay_usecs; __u8 bits_per_word; __u8 cs_change; __u8 tx_nbits; __u8 rx_nbits; __u16 pad; }; This turns into an issue on more recent kernels, where it turns all transactions into QUAD transactions, while the controller actually doesn't support that mode of operation.

* | usrp3: Added RX DSP support for heterodyne samplingAshish Chaudhari2016-03-215-17/+46
| | | | | | | | | | | | | | | | | | - rx_dsp_core: set_mux takes in a fe_connection obj to determine IQ mapping and sampling mode parameters - rx_dsp_core: Support a non-zero IF for downconversion The current strategy applies a software DSP freq offset which eats into the range of the CORDIC which is OK because heterodyne assumes real-mode sampling
* | usrp: Added fe_connection type and unit testAshish Chaudhari2016-03-212-0/+68
| | | | | | | | | | - Wraps a sampling mode and IF frequency - Built-in parser to deduce swap,invert,mode bits from string connection

| * Enable multiple programs to use USB USRPs on WindowsDerek Kozel2016-02-291-4/+6
| | | | | | | | | | | | | | Window's WinUSB driver doesn't support multiple processes accessing a single USB device and libusb_open returns LIBUSB_ACCESS_ERROR when trying to access an already claimed USRP. One device access did not catch this exception and caused UHD to error during USRP discovery.
* | dboards: Added APIs to get RX and TX frontend namesAshish Chaudhari2016-02-261-1/+21

* | dboards: Added ability to register a per-dboard container classAshish Chaudhari2016-02-263-40/+101
| | | | | | | | | | | | | | | | | | | | - The typical dboard classes are actually "subdev" classes i.e. there is one instance per dboard subdev (front-end). This makes it hard to implement shared functionality between multiple front-ends. - This changes adds the ability to create a container class which is created per group of subdevs and each subdev gets a pointer to the container class for cross linkage.
* | dboard: Made dboard class dtors virtualAshish Chaudhari2016-02-2612-39/+43
