Armbian

Exploring the Armbian sources

After considerable fumbling around, I determined that the best way for me to get a "snapshot" of the Armbian sources was to download Armbian for my Orange Pi PC 2, put it on an SD card, boot it, then run armbian-config on the target itself to fetch the sources. This seemed to work smoothly. I then put the SD card back into my desktop and copied the sources from /usr/src and am not studying them. They are for a 5.4.43 kernel.

My particular interest is the hardware initialization of the h5 chip, most especially with regard to setting up interrupts and the GIC.
