Want to write your own OS for Imagination Technologies® CI20? Or just want to investigate making a custom OS for MIPS? I’ve found a blog that has some great, practical content: Lardcave.net’s CI20 Bare-metal articles
The articles are written for people using Mac OSX but there’s sufficient information, when combined with the CI20 Wiki, for Linux and Windows users to get the project working. It also helpfully includes links to eBay for USB to Serial boards connecting wires.
Will we ever see FlingOS running on the CI20? Maybe but not for a little while yet. If anyone fancies having a go at porting FlingOS, by all means head over to the Join page!
