[linuxsh-dev] Question : GBD Stub to boot a machine.

[Fabio G. <fg...@ti...>]

Hi, every body,
I'm woking on porting linux-sh on a my own sh-3 based board.
To debug the software regarding the machvect description, I boot my card 
using sh-ilp+g and everything works good.
Now I'd like to put on the flash of another my development sh-2 based card 
the gdbstub I found on sourceforge to achieve the following target:
1) power up my card;
2) load on ram my program;
3) execute from ram my  program;
4) debug it.

Some doubts:
1) How do I have to link my application program I like to debug using gdbstub?
2) Is it possible to use gdbstub to debug a loaded program (using (gdb) load 
/root/myrog command); or gdbstub has to be a part of my application program?
3) Can I try to compile sh-ipl+g for may sh-7044 based card, or it has too 
much specific part sh-3 and sh-4 related?

Thanks for your answer.

Fabio Goiovagnini.
