GDB over a serial link (with no OS) for MIPS32

GDB over a serial link (with no OS) for MIPS32

[Srinivas Murthy]

Hi,
 We need to develop a gdb debug tool for a custom multi-processor MIPS
target running in an infinite loop (without an OS) over a serial link
with a UART. The host is an x86 machine with Linux OS.

 The single UART needs to provide connectivity to all the processors
on the target and the debug tool needs to do processor specific
commands (breakpoints, source-level debug, etc.).

 Can you guys please point me to any reference material,
implementations, etc. for me to get started with this?

Thanks much for your help.

Regards,
-Srinivas

Hi,

You'd want to write a new target in GDB. Take a look at the target
abstraction.
Look at a sample target ... lets say remote.c .

cheers

Thanks for the email.

I will need a little more hand-holding :(

Can you please give me some more pointers on how to get started?

More specifically,
 1. What are the OS-dependent and OS-independent portions of the code?
 2. Specifically using a serial port, what is transport dependent part
of the code?
 3. What is the arch. dependent part?

 Any pointers on how to get started (maybe something like a porting
guide, perhaps?).

Thanks much for your help.
