Hi,

I have an IOT-gate-imx8 that was flashed and working with balenaOS 5.3.23. I then attempted to replace the OS with Compulab’s Debian image following these [instructions](https://mediawiki.compulab.com/w/index.php?title=IOT-GATE-iMX8_and_SBC-IOT-iMX8:_Debian_Linux:_Installation).

Unfortunately after running `cl-deploy` from those instructions, I’ve somehow managed to put my device in a kernel panic and it never boots to BalenaOS (or Debian).

Here is the output from `minicom -D /dev/cu.usbserial-028A400C 115200` on my Mac connected to the console port by USB.

```

Also when I run `uuu -lsusb` on my Mac I get 0 `Connected Known USB Devices`.

Any idea how I can remove BalenaOS and get the device to boot into Debian?

Thanks
