FreeRTOS RM57 SCI DMA MPU,transfer wrong data



Hi,

I cannot transfer right data using SCI-DMA, based on FreeRTOS, the transfer data is always zero. When I disable Cache, the data is right.

I have setted MPU region 15 and linker file like demo example_mibspiDma.c, when running with out RTOS ,the transfer datas are right.

This is setting pictures belong to my project with FreeRTOS.


Except your reply.

Best Regards,

Finley Quan.
