Hi all


My customer have a problem in i.MX515.

I checked the errata and patch but there are no errata which suit for this problem.

So please advise me how to avoid the symptoms.


They're decoding mjpeg using VPU, It seems that it decodes (converts) incorrectly.

Reproducibility is not very high.
According to the log, it seems that the data of Cr is garbled one bit.
The correct data 7F and the abnormal data is FF.


Would you like to teach how to avoid it ?



I think the informaiton to avoid the symptoms is missing.

So please tell me if there is missing information.
