Rock64 bricked after upgrade

[jean_bruder]

Looking through a few similar issues on the Armbian forums, a good first step might be to run fsck on the SD. You might also try using armbian-config in chroot to downgrade your kernel.

Dear @tophneal,

Checking the SD Card show no error on the card   

I followed the link https://askubuntu.com/questions/28099/ho...ll-kernels in order to downgrade the kernel, but got the following error while chrooting :

Code:

jean@Astux:~$ sudo chroot /mnt/SDCard/
chroot: impossible d'exécuter la commande « /bin/bash »: Erreur de format pour exec()

 
This seems to be induced by different binary formats :

Code:

jean@Astux:~$ file /mnt/SDCard/bin/bash
/mnt/SDCard/bin/bash: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-, for GNU/Linux 3.7.0, BuildID[sha1]=b11533bde88bb45ef2891fbf3ad86c1869ed3a41, stripped
jean@Astux:~$ file /bin/bash
/bin/bash: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/l, for GNU/Linux 3.2.0, BuildID[sha1]=12f73d7a8e226c663034529c8dd20efec22dde54, stripped

Is there something I can do so far ? 

Regards,
Jean
