Linux: DMA pending Errors when SPI0 used in EDMA0 core

Tool/software: Linux

Hi there, I am using OMAPL138 SoC;

This is with Linux running on the ARM Core. The SDK is v4.0.0.4 and Linux is 4.9.28

In the DSP Core, I am using SPI0 to transfer data using the EDMA0 queue 14 and 15. WHen enabled I am getting following errors in the Linux log:

edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!
edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!
edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!
edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!
edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!
edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!

edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!

edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!
edma 1c00000.edma: dma_ccerr_handler: Error interrupt without error event!
edma 1c00000.edma: dma_ccerr_handler: Error interrupt without erro

Any idea, if I need to disable SPI0 in the Linux device tree? or what could be he reason of the error?

Thanks.

Regards,

Mitesh
