Cisco 9120AXi -E Boot loop

[Magnus43]

I now have 2 Cisco 9120AXi -E that does a  Boot loop. I can come in to U-boot but thats it. 

Hard Reset doesn't help.  Is there anyone who has had this problem and solved it?

Can you attach a console to the AP and show us the output of it booting?

This is the log.

Flash or memory is probably defect:

I suggest replacing it.

When consoled into the AP, there should be a 3-second countdown timer to break the boot process using the "ESC" key.  Hit that and you will be presented with a "u-boot" prompt.  Enter the following: 

setshenv BOOT part1
saveshenv

And then reboot the AP.

[Magnus43]

setshenv does not exist.

Is this the same command ?

setenv - set environment variables

saveenv - save environment variables to persistent storage

[Leo Laohoo]

Different AP firmware have different command variation.  If "setshenv" is not accepted then try "setenv".  

[Magnus43]

Same problem.

But when it reboots i says Rebooting in 5 seconds... Did not do that before.

RMA the AP.
