  • Hi My Friends.

    seem the debugger is in the Asynchronous mode . (DSDI signal is Low )

  • Greetings,

    First, update your Codewarrior using the Patch for PPC BDM:

    This should allow your software to work on latest operating systems and latest PEmicro hardware.

    • yes i did it before

  • this board is my design and after assemble the board i could not debug it .

  • Greetings, 

    Which multilink are you using?
    Have you ever had success connecting the multilink to this board? Has this multilink worked on other projects in the past?
