Hi Stefan,

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)

musb_read error -116

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!

A firmware update requires a power cycle of the evaluation board. Have you tried that? I attached for you reference the current drs_eval1.mcs file, which is meant to go into the XCF02S PROM. There were recent changes also in the DRS library, and I'm not sure if yous if recent enough. So I put also the current C files which go with the firmware. They contain also some improvements which should reduce the intrinsic noise of the board.
