Re: Issues with i.MX SPI DMA transfers

[Igor Plyatov]

Dear Robin,

I have made additional tests on another exemplar of board with 
absolutely same hardware.

The spidev_test failed on eCSPI2 and eCSPI5 interfaces, but works 
successfully on eCSPI1 interface.

So, it looks, issue does not correspond to fixed interface number.

This is generic issue of i.MX6 SOC and hardly broken eCSPI interface 
number can change from SOC chip to chip.

Do you have any idea how to improve situation with eCSPI in DMA mode?

Best wishes.
