So I updated the firmware using the following capsule: http:// snapshots. linaro. org/components/ kernel/ leg-96boards- developerbox- edk2/latest/ DeveloperBox. Cap
sudo apt install fwupdate snapshots. linaro. org/components/ kernel/ leg-96boards- developerbox- edk2/latest/ DeveloperBox. Cap 8b63-4849- 8af4-ea479356f0 e3} DeveloperBox.Cap
wget http://
sudo fwupdate --apply {50b94ce5-
sudo reboot
After the firmware was updated the box boots fine. So it's a Device Tree config issue that's fixed with the latest firmware upgrade. This is not a kernel issue per se.
