Hi, Does any one use c compiler for MC9S12DP256 for developing small code to store at RAM and execute it. I am using DRAGON12PRO board and trying to compile. I have successfully compiled and stored the code to RAM but not able to execute. I have tried to load .abs file and s record file both not working. Any idea ? Thanks Naheed |

Hi Naheed. Did you make sure that the processor's PC is set to your code entry point before running the part? Also resetting the debugger will make the chip fetch the first PC in FFFE-FFFF. If the reset vector is not programmed, set the PC yourself via the debugger Register window. You can also set the pc by command, in a "postload" command file, for example, with: RS PC _Startup (to make the pc point to the startup code (Startup function) after loading your .abs file) Best regards, Gilles At 04:36 PM 8/11/2003, you wrote: >Hi, >Does any one use c compiler for MC9S12DP256 for developing small code >to store at RAM and execute it.

Hi Gilles, After loading .abs file I opened command window and running by command "g 0x3000". 0x3000 is the program start point it gives me Start error. even I tried to set pc using "t pc 0x3000". Still it is not. I will try with postload command.

Hi Naheed. You use a CodeWarrior C compiler, but which debugger do you use? The command here below "t pc 0x3000" does not exist in the HI-WAVE/CodeWarrior debugger. If you use HI-WAVE, make sure that your code is really loaded at 0x3000. Load "read back only" to verify that your code is in ram.

HI Gilles, Sorry I used command "tp pc 0x3000" on Dbug-12 command window under True-time simulator that coming with code warrior standard version. But it throws error. Also the sRecords generated is very lengthy and that cannot be loaded by some other tool. I have try to set the burner file still no use. postload command as per your suggestion "RS PC _Startup" is giving error too. I switched to another c IDE embeddedGNU and it works fine.
