After many tweaking on hardware (cutting AT pin PowerQUICC MPC850) and software (trying many configuration , initialization sequence and timing diagram mode) the crucial part for HDLC communication is working now. So far several hardware driver already finished are :
- Zarlink digital crosspoint :
- DPLL ,
- Frame Syncronization ,
- timeslot switching for PSTN modul, E1 modul and QMC HDLC.
- QUICC Multichannel HDLC controller
Next TODOs are :
- Test Communication with IO Module :
- Match Flag and CRC ,
- Match byte allignment ,
- Establishing NRM protocol,
- Test Information Flow with IO Module :
- Functional Test E1 Modul ,
- Functional Test PSTN Modul ,
- Test Communication Flow with LE simulator :
- Match Flag and CRC ,
- Match byte allignment ,
- Establishing LAPB protocol ,
- Test V5 Protocol with LE simulator :
- PSTN Protocol ,
- Control Protocol ,
- BCC Protocol ,
- Link Control Protocol ,
- Protection Protocol ,
- Ready for testing with real LE
Those TODOs must finish before Monday ![]()
