cmsis_dspi_edma_transfer CS is pulled up during each byte

Hi all,

 

I compile and run the cmsis_dspi_edma_transfer example with my NXP MK64FN1M0VLQ12.

One issue is found that CS becomes high after sending each bytes of data over SPI.

 

While using other examples, such as edma_b2b_transfer, or dspi_interrupt, everything works fine.

No clue about where and why the CS was pulled up during each bytes.

 

Thanks

Kevin
