Hi All, I am using Code Warrior and a DP256, once I enable the PPL in the startup code, the True Time Sim seems to loose the connection to the target. Is there a trick to changing the Multilink clock rate so that the True Time Sim will keep working. Regards, Darren Moore |

Hi Darren. If your application changes (even only once) the bus speed via PLL: -make sure a PLL Loop Filter is installed. -check the "set CLKSW bit in BDM control register (MC9S12 only)" checkbox in the "Communication Device Specification" dialog (menu: "ICD-12" then "Connect..."). If you open a "Command" component, speed variation detections by the cable should be reported there. Darren, could you indicate your Metrowerks CodeWarrior version: Typing "ver" in the "Command" window gives directly a list of DLL versions. Thanks.

Hi Gilles, Thanks for your quick reply. It was the CLKSW bit in BDM control register that need to be set, I had checked it in an earlier project. For the record I'm running version 3 special edition, downloaded this copy just two days ago.

Hi. I've the same problem with Multilink BDM, and my program stops. With NoIce, my program can run without problem (but I don't know if I can debug it). So, for the moment, I use NoIce and ICC12 compiler. I hope I'll find other explanations here.

Hi Joel. I already replied to this in the newsgroup, so just pasting again: If your application changes (even only once) the bus speed via PLL: -make sure a PLL Loop Filter is installed. -check the "set CLKSW bit in BDM control register (MC9S12 only)" checkbox in the "Communication Device Specification" dialog (menu: "ICD-12" then "Connect...").
