Set configuration with PS mode by other MCU

Thanks for the reply.

I tried the .rbf file, and it works ,too.

So, .sof and .rbf both work well in download cable with Quartus.

Next, I change the first one byte and the last one byte of .rbf.

And waveform changes in the first waveform and last one.

I am convinced that I just send the whole .rbf data to FPGA by MCU, and it will work.

But the waveform of the combination of data0 and DCLK is little odd.

The following shows the waveform I capture during configuration

The CONF_DONE raise before the last data was sent.

But it seems it goes all right.

Thanks for the helping. I think I can take care of the last.
