Soldered Inkplate 6 PLUS boot loop

[gigawatts]

I can't get either the 2.0.0 or 2.0.1 release for the Inkplate 6 Plus to start. This is using the "Soldered" variant of the device (https://soldered.com/product/soldered-inkplate-6plus-with-enclosure-e-paper-display-with-touchscreen-copy/), I am not sure if that makes a difference.

Here is the boot sequence I get, followed by a reboot, over and over, with or without an SD card inserted.

Rebooting...

I have tested that the SD card can be read from, with the MicroPython firmware and this example: https://github.com/SolderedElectronics/Inkplate-micropython/blob/master/Examples/Soldered_Inkplate6PLUS/exampleSd.py
