Ok, looking at the traces this doesn't seem to be connected to the issue. Taken from one of your traces is data below We have a tef fifo size of 4, so yeah in this scenario it's expected to have TEF full situations. A larger TEF/Faster SPI/better SPI utilization would all reduce the occurrence of the issue. The A0 5D.... are UINC after transmitting a frame in the TX fifo, the A0 41 are uincs of the same TEF after transmitting a frame.
