Hi all,

I have a omnia 2020 from few days. i have configured the router and during two day is running fine.

But during one days is seem to be not working and reboot it without effect.
I connect my laptop to the serial cable and i can see the following message in loop

BootROM - 1.73
Booting from SPI flash
BootROM: Bad header at offset D4000000
BootROM: Bad header at offset D4200000
…

so i decided to recover from seria

following this documentation https://docs.turris.cz/hw/omnia/serial-boot/

i use the following file for booting u-boot
u-boot-omnia_2020-09-07-6dd804d7-1_arm_cortex-a9_vfpv3-d16.ipk

but a the end of kwboot command i get Protocol Error :

kwboot -t -b uboot-devel -B 115200 /dev/ttyUSB0

hello,

I have tried with my Raspbery pi 4 to use another serial interface
i used kwboot from installing u-boot-tools packages

i get same error but not at same step :

kwboot -t -b uboot-devel -B 115200 /dev/serial0

Hello,

Another try with new serial cable based on CP2102

i’m working on ubuntu 20.04 fresh installed for this revover.
i have download this u-boot image : u-boot-omnia_2020-09-07-6dd804d7-1_arm_cortex-a9_vfpv3-d16.ipk

To remember, my rooter is not booting.
When i check the serial output, i get this :

# minicom -D /dev/ttyUSB0 -b 115200


Bienvenue dans minicom 2.7.90

Now when i try to recover my rooter from serial i get the following issue :

rooter is unplug from power

Sending beacon in loop. You have 5-10 seconds to power up 
Omnia.

rooter is plug to power :

somebody have any idea about my issue ?

It is new Omnia so it might be hardware failure if you are saying true that you just configured it and it stopped booting. I would suggest you to contact our support https://docs.turris.cz/basics/support/.
