Thanks for that, I think i get it!

I think i may however have run into a more serious problem. Reading the manual "7.Configuring StratixII and StratixIIGX Devices" I see that the MSEL input pins have to be set accordingly to run remote system upgrade. Table 7-1 says that for Remote system upgrade with AS the value of MSEL[3:0] should be 1110.

The problem is the custom board I am using (not designed by me) does not have any jumpers or switches to configure the input to the MSEL pins. All it has is a three pin header with a jumper which when placed over the leftmost two pins is AS and the rightmost two pins PS. I assume that this is driving a single bit of the MSEL signal with the rest appropriately hardwired to support the modes AS and PS. I know that you cannot see the board but does this sound a reasonable conclusion?

I assume therefore that without being able to correctly set all 4 pins of the MSEL input i won't be able to correctly use the remote update circuitry. Is this correct? Are there any alternative methods I could consider?

Thanks,

Andy
