Other Parts Discussed in Thread: CONTROLSUITE, UNIFLASH

Hi All

I compiled and linked sci_echo back sample code to f28021 controller using ccs5. i havent seen any errors while compiling. when I tried to see the result on tera term window, I found that controller still have the previous program and I am getting the same over the terminal. I understood that the code is not loaded to controller. then how to cross verify this issue. could I get any sample code for sci driver on f28061. I feel that my sci driver has been corrupted or some files missing.

    Hi PN,

    You can find SCI sample codes here: C:\ti\controlSUITE\device_support\f2802x\v220\f2802x_examples_drivers

    Always choose the option of "Copy Project to Current workspace" while importing sample projects. If you modify the ones present in controlSuite then there will be no more sample codes :)

    If this is the case then you've no other option than re-installing the software again.

    Now, about not able to code to controller. I would like you to dump the .out file from the latest compiled project in your workspace using CCS Uniflash tool. Let me know what you observe now.

    Also, please post C2000 based questions here: http://e2e.ti.com/support/microcontrollers/c2000/f/171.aspx

    Regards,

    Gautam

    Thank u iyer,

    May I know how to erase previous program form my microcontroller?

    " No source available for "_args_main() at 0x2ca"  is the error what I get from the debug menu.

    _args_main() 0x0002CA  (_args_main has only skeletal debug info) . what could be the problem of this. Does it affect

    in my sci communication.? if so how to resolve this. currently I am using ccs5 with target configuration as usb emulator

    v2. is there any problem with this version.

    Use CCS Uniflash tool to erase the micro-controller.

    Also, even after the error you might be able to debug, right?
