QUICC Multi Channel HDLC : It’s working at last

// March 23rd, 2005

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 :-<
