Hi,

We are doing android porting for verdin-imx8mp board.Took the android 11 OS for IMX8MP which is provided by NXP & modified the u-boot & kernel code w.r.t to the verdin development board.We are able to build the android os with the verdin board changes & able to generate images.

We got struck in flashing the android image on verdin-imax8mp board. Can you please guide me the flashing mechanism for verdin-imx8mp board?

Thanks & Regards,

Siva Sankar Reddy

Hi @siva172902,

I hope you are doing well

One can flash the binary into the EMMC using the UUU tool.

Please refer to section 5.3 Flashing board images from the ANDROID_QUICK_START_GUIDE.pdf

Thanks & Regards,

Hi @siva172902,

My apology for the delayed response.

Kindly check the Kernel command line (bootargs) is set as per your board.

One can reference the section 6.2.2 Kernel command line (bootargs) from the Android ™ User's Guide.

If it does not solve the issue, kindly share the values of your Uboot environment variables using the 'printenv' command for further debugging the issue.

Thanks & Regards,
