Hello every,

   Recently, I used S32K142 SPI+DMA to transfer data and wanted to detect the completion flag of a DMA transfer. My channel was configured to send 4096 bytes from memory to peripheral, using SDK.

  Now I have detected the Done and MAJORELINK of TCD control and status, but there is still a transmission error that   cannot be transmitted .

 Must the EDMA be reinitialized after one transmission?
