Hi

I would like to update u-boot from within u-boot. As far as I found out, there existed a u-boot update command in earlier u-boot images. Unfortunately, I can not find this update procedure in BSP3.0 u-boot anymore.

Can you please tell me, how I can update u-boot (without the need to flash from within EasyInstaller) easily, which I need for fast development cycles.

Thanks and best regards,
Tonio

Hi @tgsell

Could you provide the hardware information of your module?

Hi @jaski.tx

At the moment I am working with Colibri iMX6ULL v1.1 A module.

That’s not quite fully accurate. This was really part of the U-Boot update script as part of the legacy image update procedure whose support we dropped in BSP 3.0. But I guess you could still kinda use the BSP 2.8 stuff for that.

Unfortunately, I can not find this update procedure in BSP3.0 u-boot anymore.

Yes this all got simplif culminating in the Toradex Easy Installer.

BTW: We did actually add such a wrapper at least for some of our modules.

Is it also possible to replace u-boot from within linux on the module itself?

No, you should use the Toradex easy installer or use the solution proposed by @marcel.tx.

Ok, with BSP3.0 Toradex easy installer it looks like that at the moment:

I believe you forgot to mention the autoinstall feature:
