Recently we received the new USRP2 of REV4. Then I tried to flash
firmware to 2GB SD card with u2_flash_tool but failed. The error message
sudo ./u2_flash_tool -t fpga --dev=/dev/sdj -w u2_rev3_2rx_iad.bin
Traceback (most recent call last):
File “./u2_flash_tool”, line 111, in
File “./u2_flash_tool”, line 97, in main
r = (write_flash(offset, filename, options.dev)
File “./u2_flash_tool”, line 26, in write_flash
IOError: [Errno 5] Input/output error
It works perfectly on old 1GB SD card. What is the problem?
Thanks for help!
