Hello @Chavira ,

I am using imx6ull-evk board.

In the box, I received sd-card which is already loaded with 6.1.55 kernel image, I am able to boot the board with that card.

So we can assume that there is no hardware issue.

Problem occurs when I flash pre-build image downloaded from: https://www.nxp.com/webapp/Download?colCode=L6.1.55_2.2.1_MX6UL7D&appType=license

Thanks

Deepak

Hi @deepak2!

Can you share the steps that you are following to flash the board?

Are you using the uuu tool?

Are you flashing a new SD card?

For flashing the board I recommend using the UUU tool.

Best Regards!

I insert the sdcard in laptop and use balenaEtcher tool.

I select image imx-image-full-imx6ul7d.wic and flash it to sdcard

Hi @deepak2!

Thank you for contacting NXP Support!

Are you using a custom board?

If yes, you should port the bootloader to your board because the pre-built images are only for our EVK boards.

Please check the porting guide.
