Nitrogen6 SOM can not boot from SD card

jbutler — Wed, 05 Mar 2025 15:18:17 GMT

Hi,

I am using the Nitrogen6 SOM V2 with the Nitrogen6 carrier board. I am following these instructions

https://www.ezurio.com/resources/software-announcements/yocto-gatesgarth-release-for-i-mx6-i-mx7-platforms

I use image

20210315-boundary-image-multimedia-full-nitrogen6x.wic.gz

on the SD card. When I try to boot I get the error

Press SPACE to abort autoboot in 0 seconds
switch to partitions #0, OK

Hello,

Ezurio uses two different tools to flash the image, via zcat and dd under Linux and balenaEtcher.

I suggest you follow the instructions recommended by the manufacturer.

Also, please confirm that the processor part number of your board matches with the flashed image, if you are using the incorrect image can cause the issue you are seeing.

Best regards.

I am using the Nitrogen 6 SoM V2 and the image

20220204-nitrogen6x-4.14.x_2.0.1_ga-bionic-en_US-console_armhf.img.gz

I did

gunzip 20220204-nitrogen6x-4.14.x_2.0.1_ga-bionic-en_US-console_armhf.img.gz

sudo ddrescue -D --force 20220204-nitrogen6x-4.14.x_2.0.1_ga-bionic-en_US-console_armhf.img /dev/sda

Hi,

This is because you are trying to load a device tree which is not a standard device tree from Boundary Devices / Ezurio ( imx6q-vml_cci.dtb).
Please erase your U-Boot environment and you'll see the OS booting.

Regards,
