HI @charleshuang!

What board are you using?

That links are not the official nxp repo.

If you have a development board from a partner you should contacting support in the company that is modifiying our software to their boards.

Best Regards!

Hi Chavira,

Since we don't have the i.MX6DL demo board, we are using the Advantech RSB-4411 i.MX6DL 2G board, which does not have the PMIC used on the NXP demo board.
Do you have the i.MX6DL demo board? Can you test it on Yocto 4.2?

Thanks.

Hi @charleshuang!

Yes we have a demo board from NXP but doesn´t have problems reported.

please contact to Advantech Support .

Best Regards!

Hi @Chavira 

I am the sw engineer from Advantech. 

If possible, please provide the startup log messages for the Yocto 4.2 version running on an imx6dl demo board.

Thanks about your help.

HI @charleshuang!

I don´t have that demo board at the moment I only have the iMX6Q.

I think that you have some miss configuration in the ram.

Are you doing the proper changes for your board?

I know that you have the same board running with other RAM sizes and the RAM files and configurations should be updated too according with our porting guide.

Hi @Chavira 

We have not missed any configuration in the RAM (U-Boot) because we are using the same U-Boot, which includes the DDR RAM parameters.

Do you have any advice in Kernel setting?

Thanks.

Hi @charleshuang!

I am not sure what could be wrong with your board.

Can You compare the device tree with our sabre board:
