Dear Robin,

Hi Igor,
Did you meet any issue with my latest patch?

sorry, but unfortunately I have no time to test it.

I have switched to PIO mode and continue other development.

Maybe later I will find time to test DMA mode, but not sure when.

Thank you for support!

Hi Igor,
Please have a try with the attached patches, and revert 25aaa75df1e6,
ad0d92d7ba6a , dd4b487b32a3, df07101e1c4a before apply. Besides XCH, tx
thresh should be set to 0 , now no failure caught on ecspi5.
