From b96088b692a5c44974919ee36e253b6ea8c51972 Mon Sep 17 00:00:00 2001 From: Nick Foster Date: Tue, 31 Aug 2010 16:44:30 -0700 Subject: EEPROM burning in UHD. Changed some USB device handle stuff. Added usrp_init_eeprom.cpp. Hacked up the firmware makefile to behave and to generate .bin EEPROM images instead of IHX. --- firmware/fx2/src/common/build_eeprom.py | 103 +++++--------------------------- firmware/fx2/src/usrp1/Makefile.am | 58 +++++------------- 2 files changed, 28 insertions(+), 133 deletions(-) (limited to 'firmware') diff --git a/firmware/fx2/src/common/build_eeprom.py b/firmware/fx2/src/common/build_eeprom.py index 023c4b3f5..ae62587db 100755 --- a/firmware/fx2/src/common/build_eeprom.py +++ b/firmware/fx2/src/common/build_eeprom.py @@ -29,15 +29,6 @@ from optparse import OptionParser VID = 0xfffe # Free Software Folks PID = 0x0002 # Universal Software Radio Peripheral -
