After many days spent wondering why is my OPI Zero2w 1.5GB not booting some Armbian images (xfce desktop version for example), I have found there is a "bug" or difference in uboot models 1.5GB + 4GB vs 1GB+2GB.
Fix that might work for Zero2w is here https://forum.armbian.com/topic/31654-orange-pi-zero-2w/ (planning to test it soon)
Can somebody confirm Opi Zero2W 1.5GB has still this issue with some Armbian images ? Armbian minimal boots without aby issues. Not sure why it works and desktop doesnt.
