From 81f211c94f761c92baaf1a2997a7f9b9b7718182 Mon Sep 17 00:00:00 2001 From: Josh Blum Date: Tue, 11 May 2010 16:35:01 -0700 Subject: Moved usrp2 eeprom addr read/write to host control over i2c/eeprom interface calls. No longer part of the dude/bro protocol. Simplified the mac and ip addr read write code in mboard impl. Modified the mac addr type to take byte_vector_t from serial.hpp types. --- host/lib/usrp/usrp2/fw_common.h | 10 ++------ host/lib/usrp/usrp2/mboard_impl.cpp | 50 +++++++++---------------------------- host/lib/usrp/usrp2/usrp2_iface.hpp | 7 ++++++ host/lib/usrp/usrp2/usrp2_impl.cpp | 4 +-- 4 files changed, 23 insertions(+), 48 deletions(-) (limited to 'host/lib/usrp') diff --git a/host/lib/usrp/usrp2/fw_common.h b/host/lib/usrp/usrp2/fw_common.h index f28013cf6..75f5b1779 100644 --- a/host/lib/usrp/usrp2/fw_common.h +++ b/host/lib/usrp/usrp2/fw_common.h @@ -53,13 +53,8 @@ typedef enum{ //USRP2_CTRL_ID_FOR_SURE, //TODO error condition enums //USRP2_CTRL_ID_SUX_MAN, - USRP2_CTRL_ID_GIVE_ME_YOUR_IP_ADDR_BRO = 'a', - USRP2_CTRL_ID_THIS_IS_MY_IP_ADDR_DUDE = 'A', - USRP2_CTRL_ID_HERE_IS_A_NEW_IP_ADDR_BRO = 'b', - - USRP2_CTRL_ID_GIVE_ME_YOUR_MAC_ADDR_BRO = 'm', - USRP2_CTRL_ID_THIS_IS_MY_MAC_ADDR_DUDE = 'M', - USRP2_CTRL_ID_HERE_IS_A_NEW_MAC_ADDR_BRO = 'n', + USRP2_CTRL_ID_WAZZUP_BRO = 'a', + USRP2_CTRL_ID_WAZZUP_DUDE = 'A', USRP2_CTRL_ID_TRANSACT_ME_SOME_SPI_BRO = 's', USRP2_CTRL_ID_OMG_TRANSACTED_SPI_DUDE = 'S', @@ -96,7 +91,6 @@ typedef struct{ _SINS_ uint32_t seq;
