IMX7 Config Block unreadable

Hello,

I got this error:


Sorry I couldn’t upload the file because it was too big and too small at the same time.

I would like to restore the config block for the IMX7D. I found similar problem here How to restore the Config Block - Technical Support - Toradex Community , it didn’t help me.

I also saw these:

BTW, I was unable too connect to VNC but I could ping the target. So the only method too see the error is to connect a monitor to the screen. I even looked for log. There was no log …

We are currently developing our own carrier board for IMX7. We will send our system all around the world. We have to get a solution to see at least errors without connecting a screen ! I’m really suprised that I can’t watch the error without connecting screen.

So my questions, how to restore this config block ? How can I see the error ? Do you have the toradex Installer source ? Then I can add printf ?

Thanks a lot !

Hi @arnaud_infoteam

Thanks for writing to the Toradex Community!

BTW, I was unable too connect to VNC but I could ping the target.

Did you use the Ethernet Interface? We tried it out and it was working. Did you get any error?

If you use the RNDIS Interface, it is not possible yet to connect using VNC in case of missing/corrupt config block, since the Interface is not present in this case. We will try to correct this in the future.

So my questions, how to restore this config block ? How can I see the error ?

If you have still working U-Boot, then you can use this to create the Config Block ( Command: cfgblock create ). If not, then you can use VNC connection to the module and create the Config Block.

Thanks it works with U-boot.

After this the MAC address was ending with 00000. So I found the method there: MAC Address | Toradex Developer Center

setenv ethaddr
saveenv

Then problem solved without connecting VNC !

Perfect. Thanks for the feedback.

Best regards,
