I have a problem with the UDP sendto(). Looking at the SPI it seems to transmit data but the response from DMA_EXT_WRITE (C7) is a bit weird. (Check picture below)


Where it should be response C7 00 F3. I get the F3 from the MOSI instead... Other commands don't have this problem, its only on C7 response.

Is this normal for DMA_EXT_WRITE or is this possibly the problem for not getting UDP packets on the other line?


I followed the udp_server/client_examples. Receive works, send doesn't. I get into the SENDTO state, but sendto() doesn't send it seems.
