 Facing an issue with SDMA of i.MX 6SoloX cortex M4:

 

1] using memory to ECSPI and ECSPI to memory transaction.

2] When the dma channels were started for ECSPI's Tx and Rx, both MOSI and MISO shows correct data on the CRO.

3] However upon channel completed, the destination memory buffer is always 0x00/0xFF.

4] using OCRAM as data memory from  <0x00928000> for 256KB. (using L2 cache memory as OCRAM).

 

What could be the reason ?
