There's a newer thread on this very topic that discusses and contains a solution how to configure and use two SPI devices (via CS0 and CS1), see https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1455897/am623-questions-about-am6231-m-nuclear-procedures-and-dma-conflicts/5591394#5591394

Closing this older thread here accordingly.
