Hello Michael
Thanks for the feedback. Will try to contact MRF.
Side question, the firmware on MRF website is it for the processor or the FPGA or both? Should I update the processor only or both?
Best Regards,
Abdalla.

We tried downgrading the firmware for spare EVG and EVR boards which have the MRM firmware 005 I think to firmware E403 and D507 respectively. I followed the procedure in the manuals but when I issue the command "u" to start the update process, the telnet session exits with message "Self-programming triggered". I came back after a while and every time I telnet to the board, it seems the device entered a mode where no command is available (only q and x commands), sometimes when the device reboots, I try to dump the memory I get "Addr 0x8000002e: error -1".

Back when I was at BNL I was able to successfully update firmware on several VME boards (I assume that's what you have). I was always nervous though.
I can only recommend contacting MRF. If you are lucky, and have access to a JTAG programmer, you might be able to directly re-flash the firmware yourself.
