I have an old-version DRS4 evaluation board which doesn't have the latest firmware. I tried to flash the drs_eval1.ipf boundary scan chain into the XCF02S PROM with Xilinx IMPACT, and the firmware seemed to go through into the PROM. However, when I started the DRS command line interface to test the firmware it kept on reporting errors like
musb_write: requested 10, wrote -116, errno 0 (No error)
musb_read error -116
musb_write: requested 10, wrote -22, error 0 (No error)
and so on. Finally the program made a dumb recognition of the board as
Found mezz. board 0 on USB, serial #0, firmware revision 0
Do you have any idea which caused this problem? Thanks!
