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.
