Why Does SPI DMA Circular Reception Fail When CRC Is Enabled?

Someone is using the STM32G4 internal SPI configured as a slave full-duplex mode, using DMA for receiving. When the DMA is configured to CIRCULAR mode, problems occur where data transmission results in CRC verification failures and reception anomalies. If the DMA transfer mode is configured to NORMAL, there are no issues, and the received data … Read more
