Googling about for an open source OS that would work for a Wii (embedded PowerPC 740/750 work alike) homebrew project and I’ve narrowed my choices down two categories: a real-time OS or an embedded Linux based OS.
While I’m more comfortable with the toolchains and feature sets provided by a “full blown” embedded Linux, BlueCat Linux for example, I like the configurability and architectural layering philosophy of eCos, while RTEMS has cool points for being used in space projects.
My main concerns with eCos are: it does not have a USB stack (only USB Slave code is included); no Bluetooth stack; and does not appear to support dynamic loadable libraries. Probably, need to just go check out the GameCube/Wii Linux scene.
