Hello everyone and @robertferanec

Im testing the sabresd sdcard image on a different board based on the sabresd board with the same cpu but this board has 2Gb ram and sabresd has 1Gb. I am able to see the uboot in the serial console but then ı get an error saying :

mmc: no card present ***Bad device mmc 1 ***
Booting from net ...
***ERROR: ' ethaddr' not set***
Bad Linux ARM zImage magic!

I believe its looking for the booatble mmc 1 memory on the board but cant find kernel there so its looking at ethernet but still cant find it. However my kernel images is in the sd card which i think is MMC 0. how can I tell uboot to find the zImage in sdcard or is the image totally incompatible with my board due to RAM difference etc..???

In uboot use help command. You may also need: printenv, setenv and other commands. You may need to update environmental variables.

There are differences between different uboots, but maybe this can give you an idea how setenv works: https://www.imx6rex.com/open-rex/sof...cto_try_kernel
