Corrupt bootloader recovery for WR32X

Installing and Using OpenWrt
1

Hi all,

I'm trying to restore bootloader of wr32x via USB-TTL cable. https://oldwiki.archive.openwrt.org/toh/linksys/wrt_ac_series#tab__armada_3853 On this page, step 5 won't work for me. However It stops and gets non-responsive at 99%.

Router's boot log is :

BootROM - 1.73
Booting from NAND flash

Serdes Lane 4 is SGMII

And that is it.

Any ideas?

Change the env var silent from 1 to 0. I'm pretty sure you're just getting hit with the default console shutout.

3

How can I change that?

4

I think it's

setenv silent 0
5

But which CLI? I'm not able to get to command prompt, it stops before that.

Sorry didn't read you're doing bootloader recovery. I was referencing the uboot prompt.

:slight_smile: That is the entire problem, my friend. I'm trying to get to there.
