[ECOS] info threads command from gdb

[ECOS] info threads command from gdb

[Phung Te Ha]

Hi everyone,
	I am porting eCos to a custom board and currently
looking at
debugging tools. There are 2 points I'm a bit
confused, if someone can help:
	1. Thread list: although thread list has been turned
on, it looks
like the command "info threads" from gdb gives
nothing. I fall back to the
linux simulator and it behaves the same: run the
example "twothreads" ,
ctrlc it and run "info threads", the command comes
back with nothing.
	2. ^C support: is this supported on all platforms.
The one I'm based
on is edb7xxx, is it supported on this particular one?

Thanks.

Phungte

Linux would indeed not do anything. You may be using old GDB stubs in the
edb7xxx flash that may not support thread debugging unless you enable
"Include GDB stubs" in your downloaded application. You can either enable
that option in your configuration, or perhaps consider switching to RedBoot
- see http://sources.redhat.com/ecos/ and click on Supported Hardware, and
then the "More Info" link for your board. That will point you at RedBoot
binaries to program into Flash in the same way as the GDB stubs.

Yes.
