Hello,
I wanted to have SPI with DMA RX, below issues I face:
1. When SPI RX DMA function used with no TX DMA configured in MX (but blocking SPI TX used), It remains in RX busy state
2. When SPI RX DMA function used with blocking TX function, SPI works but code hits breakpoint in TX DMA interrupt, even if DMA SPI TX function not called but SPI TX DMA configured in MX tool.
3. When does DMA interrupt occur for SPI TX and RX?
4. How to check DMA SPI callback
Please check above queries
