I used that suoftware on the IMX6ULL EVK kit and it built okay

[JorgeCas]

Hello, I hope you are doing well.

Could you please share me more about your hardware setup? Such as device used, software versions, modifications, etc.

Best regards.

[duyhai]

Can you tell me in more detail about the hardware you need to be able to detect the error? I designed iMX6ULL with PMIC 1550

[JorgeCas]

Hello,

Your logs indicate that you are using a Variscite DART-6UL board.

Did you try with Variscite BSP?

Best regards.
