I installed the latest torizon with evaluation using easy installer. There was no serial comms after reboot. I have a SD card with easy installer and nothing boots with that either. This is the 1st time I’ve ever had this. I’ve done this several times in the past couple months.
Unfortunately this seems to be the case of you having an i.MX8X with an older silicon revision. Due to technical changes we could no longer support older silicon revisions of the i.MX8X on our Linux BSP (including Torizon). Going forward the only official support we have that is still compatible with the i.MX8X will be our 3.0 BSP (non-torizon).
As for un-bricking your module, you’ll need to put your device into recovery mode as described here:iMX Recovery Mode | Toradex Developer Center
Then you can load Easy Installer via USB OTG.
Again though I must stress that any issues that arise from this use of older silicon will be hard for us to support/debug. Apologies for this inconvenience.
