The current master plan
Done
- Use inexpensive Calypso based phones like the MotorolaC123 to do our software development
- Write drivers for the Calypso-internal controllers and the DSP shared memory API (done)
- Write drivers for the external chips like TWL3025 and TRF6151 (done)
- Build a simplistic Layer1 implementation on top of our drivers (done)
- Build a Layer 2 implementation on top of the Layer 1 (done)
- Build a simplistic Layer 3 (RR/MM/CC signalling) implementation on top of the Layer 2 (done)
TODO
- Port some minimalistic RTOS that already supports ARM7TDMI well to the Calypso
- Attempt to move L2 from PC into the phone
- Attempt to move l3 from PC into the phone
- Implement measurement reports
- Implement in-call hand-over
