This second (pre)release builds on the first, with very little visible change. However, behind the scenes, the MMU is now enabled, and so are interrupts. There is some basic PCIE initialisation on the Raspberry Pi 400, but device enumeration remains to be written.

Extract the debug/release zip file to an MS-DOS formatted SD card and insert that in your Raspberry Pi, or
