Re: Issues with i.MX SPI DMA transfers

[Igor Plyatov]

Dear developers,

I have update about these issues.

12 hours testing show very fast (some seconds) appearance of byte 
duplication at interface spi4 (alias for ecspi5), while interfaces spi0 
(alias for ecspi1) and spi1 (alias for ecspi2) work flawless (at least 
without any other OS load).

Looks like, ecspi5 has some different configuration in SPI or SDMA 
drivers or bug in SDMA script.

Any ideas?

Best wishes.
