Kernel panic/oops on Colibri imx6

I have a new Colibri iMX6DL 512MB IT V1.1A on which I tried to install a custom made linux image, as already have done successfully with a number of Colibri devices, using the Toradex Easy Installer. I use an Iris board connected to a Linux desktop using Remmina for VNC.

The installation failed as shown below:

[upload|TX0isyc9dO9q91s1bQ8SwOKmSH8=]

After that I used the Toradex Easy Installer 1.7 recovery-linux.sh to start over. This time I selected the Toradex Embedded Linux Demo with LXDE (Stable). It failed again as shown below:

At the same time at the console I got:

/ # [  147.667429] EXT4-fs error (device mmcblk0p2): __ext4_new_inode:1015: comm tar: failed to insert inode 16986: doubly allocated?

Any ideas on how to proceed?

hi @babis

Welcome to the Toradex Community!

Could you provide the version of the Software of your module?
Which devices are connected to the Iris Board?
Could you try to reinstall the Bsp 2.8b5 using Toradex Easy Installer without connecting any devices to the Iris Board?

Best regards, Jaski

Hi @jaski.tx

Thank you for your response.

I don’t get your first question, what software are you referring to?

I have connected to the Iris Board:

  1. Power cable
  2. Ethernet cable
  3. Serial cable
  4. USB cable in order to use the Toradex Easy Installer recovery script

Nothing else was connected to the Iris Board during the installation attempts mentioned on my first comment.

I did install the bsp 2.8b5 version using the Toradex Easy Installer without any problems either during installation or during boot. The problem now is that when I try to install the 2.7 version, eMMC boot fails:

Hi @babis

Thank you for your response.

You are welcome.

I don’t get your first question, what software are you referring to?

I meant, which Bsp are you using exactly, but I already got the answer.

The problem now is that when I try to install the 2.7 version, eMMC boot fails:

Did you install Bsp 2.7 using Toradex Easy Installer or the legacy update Procedure?

reading zImage
** Unable to read file zImage **
emmcboot failed
You need to reset your uboot Environment by doing the following:

env default -a
`saveenv`

Best regards,
Jaski

Hi @jaski.tx

I installed Bsp 2.7 using the Toradex Easy Installer. Resetting uboot environment did fix the boot issue but the kernel panic remains during boot.

So this related to the Bsp used, right?
Why is this happening only to one, at least up to this point, Colibri?

Regards, Babis

Is this a regular 2.7 kernel or did you customize it? If it is a custom kernel, could you provide then kernel configuration then?
