Hello I was flashing Android Auto in my module. (automotive-10.0.0_2.2.0_image_8qmek2)
It gave this error :

avb_ab_flow.c:30: ERROR: Magic is incorrect. avb_ab_flow.c:112: ERROR: Error validating A/B metadata from disk. Resetting and writing new A/B metadata to disk.

Now the module doesn’t do anything. No response and power leds like flashing.

Can you help me about it ?
Thank you

Could you please try to do recovery and load Toradex Easy installer as described here - Downloads & Installers | Toradex Developer Center

In case of further questions please provide HW version your Apalis iMX8 module and name and HW version of carrier board you are using.

I tried unfortunately, It stops like it:

1:6 1/ 1 [=================100%=================] SDPS: boot -f …/imx-boot

Which version of Toradex Easy installer did you use?

Which version of Toradex Easy installer did you use?

apalis-imx8_toradexeasyinstaller_2.0b5-20200519 this version that i use.

Toradex Easy Installer should boot OK but you will not have a UI. So lease try this workaround:

  • Unpack apalis-imx8_toradexeasyinstaller_2.0b5 to USB stick or SD card

  • Edit a json file and set parameter autoinstall: true

  • Download and unpack to your dev machine apalis-imx8_toradexeasyinstaller_2.0b2

  • Insert that media into carrier board

  • Put Apalis into recovery mode and run “recovery -xxx” script to download TEZI 2.02 over USB

  • Upon boot up TEZI 2.05 should be flashed automatically. Just wait 2-3 minutes and then reboot.

Hi @alimert,

My colleague @alex.tx meant that, from the downloaded Toradex Easy Installer, you shall run the the recovery script on your PC to load the Toradex Easy Installer in the board.
The recovery script can be either “recovery-linux.sh” or “recovery-windows.bat”, that’s why the “-xxx”. Again, you shall run the script according in your PC, according to your operating system.

Please be aware of the necessary connections for a Recovery Mode on Apalis iMX8:

By the way, which Carrier board are you using? A custom or Toradex?

Best regards,
André Curvello
