How to debug existing code in CCS without flashing a new code.

TMS320F28379D: Putting device in debug without flashing (Projectless debug)

Tool/software:

Hello Experts,

Is there a way to put MCU in debug and access the memory and registers and possibly disassembly without reflashing any new code? I am using TMS320F28379D and XDS110 JTAG.

Regards

    Yes, you can start a debug session by opening the corresponding .ccxml file (under C2000 Ware, device_support/f2837xd/common/targetConfigs), then run -> debug and after you've connected to the target, you can Run -> Load -> Load Symbols ... and pick your linker output. Last step is optional, but would give you access to the symbols, if you have the linker output.

    Hi,

    Torsten, I tried this. I can access the disassembly and the memory map. With the .out file, I can see expressions as well. But it doesn't tell memory allocation. 

    So If I understand this correctly, We have a built-in disassembler that reads binary from Flash and converts it to Assembly.

    Similarly, Do we have a decompiler that can convert this assembly to High-level C code? 

    Regards

    Hi Vishal,

    We do not have a de compiler that I am aware of to convert assembly to high level c code.

    Memory allocation should be given from the .map file and linker command file (.cmd file). 

    Best,

    In general, it's never possible to generate High-Level C code from assembly, that comes close to the original code, as there is a lot of information that gets lost during compilation.
