[SOLVED] FreeRTOS aware in Segger Embedded Studio

  • Hello,

    Well, after a bit more digger, it appears the OZone application is where Segger offers OS aware debugging. And it does a reasonable job, with FreeRTOS on the nRF52.

    NOTE: When I first got it going, it would get stuck attempting to run code under 0x0001000. It was exercised during the call to either vPortStartFirstTask or sd_softdevice_enable. Either way, after a lot of hunting I found that the solution was to replace to functions in the .jdebug file with:

    Source Code

    1. void AfterTargetReset (void)
    2. {
    3. unsigned int SP;
    4. unsigned int PC;
    6. SP = Target.ReadU32(0);
    7. Target.SetReg("SP", SP);
    8. PC = Target.ReadU32(4);
    9. Target.SetReg("PC", PC);
    10. }



    and


    Source Code

    1. void AfterTargetDownload (void)
    2. {
    3. unsigned int SP;
    4. unsigned int PC;
    6. SP = Target.ReadU32(0);
    7. Target.SetReg("SP", SP);
    9. PC = Target.ReadU32(4);
    10. Target.SetReg("PC", PC);
    11. }
    Display All
