gdb on linux on M54455EVB: illegal instruction

I cannot get gdb to work on an M54455EVB unit, running the Freescale Linux BSP.  It starts ok, and it disassembles the binary ok, but any attempt to run the program results in an Illegal instruction. 
 
Has anyone had any success with gdb?

I get the same thing, even with the simplest program. Get illegal instruction from _dl_debug_state.

It would help to know what bsp/kernel you are using.

 

Assuming you're using 2.6.25 this patch might help.

Thanks for that Kurt. I'm using the BSP from this website dated 12/14/2007 and the update dated 08/08/2008. What is the status of the patch? Presumably it is not an official Freescale one? Is there some other source I should be checking for patches?

 

Could you explain how to install the patch? The only LTIB documentation I can find on patches is about how to make one, not how to install one. Tried sticking the file in various places that contained other patch files but didnt have any effect and there doesn't seem to be any LTIB commands for installing patches.

 

Thanks.

Jon.
