Hello,
I'd like to know, wheather is there any way of upgrading u-boot different than upgrade it via running u-boot.
If new u-boot doesn't run correctly, I will not be able to downgrade the system back to previous u-boot version.
In PicoMOD1 I used stepping stone for u-boot debugging and upgrading, but there is no stepping stone in PicoCOM3. Could NBoot be used for such upgrade or is there another way?
Thank you,
Kamil
