Hello,

I installed TorizonCore 5.0.0 on an iMX8 but I can not boot it.
This is the serial output:

I do not get any output via hdmi.

Do you have an idea howto solve this problem? Thank you for your help!

Hi @Flo,

Unfortunately the TorizonCore 5 is still unstable, as it does not have an official release.
So you may face issues like this.

Just for an internal feedback for my side, which release of TorizonCore 5 are you using?

Either way, I’d suggest you to use TorizonCore 4 for the moment.

Best regards,
André Curvello

Hi @andrecurvello.tx,

thank you for your reply, I am not sure which version it was exactly (I am working on a different project atm) but I guess the latest nightly version from that day. Before I tried it with TorizonCore 5 I tried it with TorizonCore 4 but I didn’t even get any serial output.

Best regards,
Flo

Hi @Flo,

In addition to what André has said about trying TorizonCore 4 since TorizonCore 5 is still a work in progress. You should also note the known issue listed here: Toradex Easy Installer - Release Detail

You may also be affected by this issue in this specific case. In short, for the time being make sure to use recent builds of our Easy Installer tool when flashing software on the i.MX8. For more details please see here: Downloads & Installers | Toradex Developer Center

Best Regards,

Hi @Flo and @jeremias.tx ,

Currently the nightly builds of Toradex Easy Installer are having the TEI-649 fix.
You can download the latest nightly here: JFrog
