CZ-TAW1 reflash

[pampyras]

Little offtopic, but: Does anyone know how to reflash to and/or has original firmware? Device is in infinite reboot loop, so cannot be flashed with usb drive, only by serial with tftpd. Tried different kernel versions, same.

Depends what you did.... Try to change side , from printenv you will be able to see ,on with side you are actually: https://github.com/Egyras/HeishaMon/issues/19#issuecomment-630376848

[pampyras]

Thanks, it looks like side 1. Maybe you can share address of rootfs to copy to?

[MiG-41]

This is valid for SIDE 1 ( when is SIDE 2 mtd2 is swapped with mtd4 , mtd7 with mtd8 - or something like that)

I tried to boot from kernel1 and kernel2, same boot loop. Maybe propblem with hardware? Before kernel update I was getting squashfs coruption errors.

Looks like it is stucking on USB detection , perhaps you have somthing in USB ? Or controller USB-TTL controller is damaged.... Did you set to SIDE 2 as well ?

[pampyras]

USB is empty. Yes the same problem with side2, reboots at the same place.

[pampyras]

Maybe possible to disable usb at all if problem is hardware?

[MiG-41]

But to do it you should remove usb drivers from kernel.... I don't hink there is a possibility to disable USB from uBoot.
