    Hi all,

    Just an update to this issue.

    The problem has been resolved by disabling the alt_printf statement in my C code. My .pof works now, and it can send the spi commands after power cycling the board.

    My guess is that as there is no communication between the board and the nios2 terminal, the alt_printf pointer got lost when executing the function. Hence when loading .pof, all alt_printf must be disabled.

Hi Fathulnaim,

Thanks for your file. I have loaded the .sof file from the ready to test folder, and changed the bsp settings as per your steps. However, I do not see print outs on Nios II console(as attached).

Any updates on the virtual meeting mentioned in your email? I think it could be better if we have a call and settle this issue.

Regards,
