Hi,

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

I use image

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

 
as stated on the page

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,
