GDB debugging and DSP

GDB debugging and DSP [Copy link]

I would like to ask if anyone has used GDB to debug DSP bare-metal programs. I am not referring to the traditional Debug function provided on CCS, but running the GDB program on the PC and debugging the program on the DSP through a JTAG emulator with an Internet port, such as reading and writing registers, memory, setting breakpoints, single-stepping, etc.

Because I think this is not feasible. If anyone is familiar with the principles of GDB, they know that this is a program developed based on Unix and can be used to debug arm, because arm can run the Linux operating system, thereby running the corresponding gdbserver program, and then debugging the arm program through system calls.

However, since I don't know much about DSP and have little contact with it, I think that if it is a separate DSP architecture, the operating system should not be able to run on it, so gdbserver will not be able to debug the program through system calls.

But I have another idea, which is to have an arm-controlled network port emulator with a JTAG interface in front of the DSP. I run gdbserver on this emulator, complete the command conversion, and then pass it to the DSP through the JTAG interface to realize DSP debugging. I just don't know if this idea is feasible.

Because I don't know much about the DSP architecture, nor do I know how to debug DSP, so I would like to ask in the forum if there is anyone familiar with DSP who can answer my questions!

Thank you very much!

I am not familiar with this area. o(︶︿︶)o Alas, I have thrown all the useless things I learned to the teacher. I learned DSP when I was in school, but now it seems that he doesn't know me and I don't know him.

He may still know you, but you may not know him.
