[ECOS] GDB / Realview Micro Edition ARM7

[Moussa Ba <mba at embedded-zone dot com>]

Good Day,

I am using ARM's RDV for oki which uses a RealView Debugger with an 
ICE.  I produce an elf from gcc and them convert it to binary which I 
burn with RealView.  I also use RealView to step though some of the code 
(any program that I write and link it with the library).  Unfortunately, 
it has been difficult to diagnose ecos code in the library.  RealView 
has difficulty locating sources from the based on the symbols it loads 
from the elf output.  I think it is a combination of cygwin tools with 
its path hierachy and RV expecting regular pathnames. 

This has made my debugging of device drivers difficult as I can only 
look at and step though assembly language code.

Does anyone have experience debugging ecos code with RealView?

I am looking now for an alternative to debugging the code.  I was 
thinking that one possibility is to use GDB and compile in gdb stubs for 
ARM for my ecos image.  I am not using RedBoot, I would like to just be 
able to flash the ARM with RealView, then debug the code with GDB via 
the serial port.

Is this possible?
The ARM has about 16K or RAM, is this is within GDB stub requirements?


Any other suggestions for dealing with this issue?

Moussa
