Issues flashing example image to board based off the i.MX8MM

SpencerLommel · ‎07-01-2025

Hello, I am trying to flash the "LF_v6.6.36-2.1.0_images_IMX8MMEVK" example image I downloaded from the i.MX 8M Mini Evaluation Kit Website onto my board but it is getting stuck at 100%

My board isn't the exact i.MX 8M Mini EVK but it is extremely close and it came pre-flashed with an image on it. I was also given the following files in case needed so I may need to use some of these while flashing I think but I'm not exactly sure what files I would need and how I would incorporate them into my new uuu.auto flash script

files I was given:

➜ dev-block-byname ls
boot_a.img boot_extracted cert.img dtbo_a.img facres.img metadata.img mnt_system mnt_vendor presistdata.img system_a.img vbmeta_a.img vendor_a.img

I also have a dtb/dts as well but I believe it's the exact same as the original imx8mm one

Here was my unsuccessful attempt to flash the default example image to my board:

Please let me know if you need any more of the boot log from the original device firmware to help troubleshoot this. It came with an Android image flashed and I am attempting to flash the default linux image to this board instead.

Hi @SpencerLommel!

Thank you for reaching out to NXP Support!

Could you please let us know which board you're using?

Please note that the prebuilt images we provide are intended specifically for our EVK boards. For custom hardware, you’ll need to port our BSP to your platform by following the steps outlined in our Porting Guide.

If you're using a third-party development board, the software support should typically be provided by the manufacturer of that board.

Best regards,
Chavira
