    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,

After compilation with 20.1 lite, I got the same result(20_1_Spi_After_Compilation) that I have been getting, 2 "$HELLOABC" and stops there.

I have notice some difference between the .hex file I have generated(proj_qsys_onchip_memory2_0_After_Compilation) and the one in your software folder.

May I know more about your working scenario? After you power cycle the board, you are able to continuously send out "$HELLOABC"? The Tx and Rx LEDs should be blinking continuously right
