[ECOS] Should GBD recognize ECOS Threads ?

[ECOS] Should GBD recognize ECOS Threads ?

[Raymund Hofmann]

Should GDB be aware of the threads in ECOS ?
In my experiments so far, for example running the example : "twothreads",
GDB seems not to list the created threads.
In the configuration by default "CYGACC_CALL_IF_DBG_SYSCALL_SET" is checked,
but the entry
CYGNUM_CALL_IF_DBG_SYSCALL in the virtual vector table points to :
"nop_service" int the rom Monitor, before and after downloading and starting
a ram application.
Am i guessing right that this is currently not implemented ?

Yes GDB should be aware of eCos threads, but without basic information we
can't help you work out why not. What is your ROM monitor (if not RedBoot,
what age is it as well)? And what is your platform?

My Redboot ROM monitor is a build from last weeks cvs.
Platform is Triscend A7 eval Board, i adapted a 1.3.1 Board-Package from
Triscend to the actual ecos CVS.

In that case, there is probably some initialization of the virtual vector
interface that you missed, I would guess. Perhaps compare against another
HAL that supports virtual vectors (note that not all do, but most do and
all new ones do).

The virtual vector table was not fully initialized, because there are two
configuration flags:

CYGDBG_HAL_DEBUG_GDB_THREAD_SUPPORT
CYGDBG_KERNEL_DEBUG_GDB_THREAD_SUPPORT

and both have to be checked, but only the first was as I tried.

It takes some time for me to figure out the different configuration options
and how they are used...
