Help, my WRT32X bricked

xwwzmrxqy · August 19, 2022, 5:29am

It can only boot with oem firmware.
When I flash with oepnwrt or other non-oem firmware, it always stuck at "starting kernel".

I connet via serial, it seems like cpu and memory freq are error.But How to fix it?

First place to look:

It is not much different than upgrading the OEM firmware - download the factory.img for your device, and follow the flow from the above link.

I don't know how to check the cpu running frequency in u-boot.

I have successfully installed openwrt 1 year ago and running several months, but one day it suddenly failed to start.So I tried reset, restore OEM firmware, web ui installation, usb-ttl installation, restore u-boot, even tried dd-wrt, Mcdebian. It seems like the frequency of cpu and memory is wrong.
I want to know if the frequency of cpu and memory is hardware controlled or software controlled.If it is hardware controlled, does it mean that my CPU is broken?
