Dear team,


I would like to ask about SDMA script for i.MX6SoloLite.

My customer is facing the issue that missing data can be seen on UART communication using SDMA on their i.MX6SL board.

Sometimes interrupt for RX data could not occur on their system.

They think SDMA script has a bug and it is the cause of this issue.

The attached file is the SDMA script they are using and it is included in your platformSDK.

Could you show me whether such problem was seen on the past PlatformSDK?

And could you show me whether the difference exist between the attached file and the latest LinuxBSP?
