Hi,
For the SIM reader, how about using SAP (SIM Access Profile) ? Originally it's a bluetooth profile http://www.bluetooth.com/Specification%20Documents/SAP_SPEC_V11.pdf. It's not as powerful as PC/SC, because SIM in mind instead of SmartCard, but it makes it much simpler and lighter (could be integrated in futur ROM). The specs are small. There should then be a SAP server for the card reader, and osmocom would have a SAP client. This architecture would provide the possibility the access the SIM card also from a client on a computer, but also have a SIM server on the computer for osmocom (using standard PC/SC card reader).
Greetings, Kevin

Hi!
I think we corrently have the following TODO list.
GSM Layer 1:
- implement transmit power control for transmit
- implement SDCCH/8 on TS1-7 (Sylvain)
- implement frequency hopping
- proper split between synchronous and asynchronous part of L1 (Harald)
- TCH/F support (Dieter, after L3 RR/MM/CC is working)
- A5/1 and A5/2 encryption support
GSM Layer 2:
- implement a real layer2 that deserves the name (full LAPDm implementation)
- properly encapsulate / abstract the L1 "MPH" primitives so L3 doesnt call L1 directly anymore
GSM Layer 3:
- test most of the code that Andreas has written (depends on L1 / L2)
Misc:
- SIM card driver + ISO7816 FS API
- Battery charger driver
- UI framework
- minimal journalling flash file system
- decide which RTOS kernel we want to use (Harald)
- fully support a working firmware build for the openmoko gta01/gta02 GSM modem using calypso romloader
For people who don't feel like they can take any of this work, there is some other work, regarding the mid-term port to our next target platform:
- implement host utility for the medaitek MT622x romloader serial protocol
- try to get a minimal hello world codebase to run on the MT622x
- write hardware drivers for UART, PMU, I2C, SPI, ... of the MT622x
Regards, Harald.
