User:NeddySeagoon/Neddyseagoons ARM64 Binhost
A long time ago I was offered a Mudan motherboard. It served as a Raspberry Pi3 and Raspberry Pi4 arm64 build box. With 8 cores adequate cooing and enough RAM to build in RAM, it built for my Pi3, Pi4 and Asus R13 Chromebook for several years.
A year or so ago it was retired in favour of a Hawk. With more RAM and more cores, it built things faster.
The Mudan used the first ever arm64 CPU. Just armv8-a+nothing. It was the only one ever with no extensions.
The Hawk is a later iteration.
Pi3 and Pi4
That just worked. At least, I'm unaware of any problems, which may not be the same thing.
The Pi 5 is armv8.2a+crypto.
That's going to be more difficult to build for on the Hawk.
So far building gcc fails with an illegal instruction.
