Hi Support, 

We would like to check if there is packet loss in espi or DMA system. Would you please advise if there is a way to see if device has this problem ?

Hi Steven 

there are some ecspi errata (please check for specific part), for example

for i.MX6DQ:  https://www.nxp.com/docs/en/errata/IMX6DQCE.pdf 

Except those there are no known issues, provided that FIFO overflows do not happen.

Best regards

Hi Igor,

We use I.MX6ULL. Does I.MX6ULL fix these ECSPI issues already ?

Thanks.
