ARM – Vim3-Pro – with EFI and Fedora 33..

Adventures With Linux ™ Posted on by

Recently acquired one of the Khadas VIM3-Pro arm64 SoCs, and was impressed with the level of documentation available.. Unfortunately – as is so often the case – this was all relentlessly Ubuntu-focussed, with a semi-proprietary kernel based on the 4.X kernel tree.. At least the U-Boot version was fairly recent, and appeared to support EFI etc.. The … Continue reading →
