U-boot update script

hello!
We have to update the u-boot of apalis-imx6 that are embedded in a cabinet where there is no access to the board via rs232 or USB. The only way is to access through a local ethernet network.

My intention is to update the u-boot using some script that flashes the /dev/mmcblk2boot0 partition somehow.

I have tried to dd u-boot.img directly but it doesn’t work.

How should I do it?

Hi @LordXor !

Which BSP version are you using in this module?

Also, which exact version is the Apalis iMX6 module?

Best regards,

Hi @henrique.tx !
How can I know the BSP version?
I am building a custom image with yocto using the toradex layers dunfell-5.x.y if you mean this.

The IMX6 module is V1.1Y

Hi @LordXor !

Seems like your U-Boot is not in the default location.

Could you please share more information about the setup of your module?

Best regards,
