hi
I have a MPC860T board with a MBX based
eCos/RedBoot self made port.
With the snapshot of today (04-Sep-2001)
my twothreads example does not work any longer.
it hangs somewhere in the second call of cyg_thread_create:

After you did a cvs up did you go all the way through the ecosconfig
new, import , check, tree etc. My guess is you have an mix of old and
new header files which is causing a problem. Try building eCos from
clean in an empty directory.

I start with a clean build dir. But i am making some changes after
getting the new eCos version (adding my HAL, diagnostic serial driver
and flash support).
But i dont change something in the kernel/ tree.
still searching for a solution
thanks, christoph

Well, the synthetic version compiles and runs OK.
The assertion is saying that the C struct cyg_thread, as defined in
kapidata.h is a different size to the C++ clase Cyg_Thread as defined
in thread.hxx. These two should be identical, member for member.
Maybe something is happening with the HAL specific entries in these
structures. Things like the register set? You will have to compare
then and see whats different. That should give a clue as to whats
causing the problem.

I have a snapshot from 30-Jul-2001(it works)
and from 04-Sep-2001 (doesn't work).
(MPC860T based platform, MBX based port, gcc 2.95.2)
Fact is that both versions of thread.hxx
(where Cyg_Thread is defined) files are identical.
In the working twothreads application (i get no asserts)
sizeof( cyg_thread ) is 176 and sizeof( Cyg_Thread ) must
be the same.
In the not-working application (version 04-Sep)
sizeof( cyg_thread ) is 186.
Since thread.hxx didn't change beetween the two versions its
clear that i get the an assert on
CYG_ASSERT_SIZES( cyg_thread, Cyg_Thread ); (186 != 176).
maybe there is problem in how the compiler packs the struct
cyg_thread.
30-Jul: install/include/cyg/kernel/kapidata.h
struct cyg_thread
{
cyg_hardwarethread hwthread;
:
.
}
here we have the struct cyg_hardwarethread as first member
of cyg_thread.
vs. 04-Sep: install/include/cyg/kernel/kapidata.h
struct cyg_thread
{
CYG_ADDRESS stack_base; /* pointer to base of stack area */ \
cyg_uint32 stack_size; /* size of stack area in bytes */ \
CYG_HARDWARETHREAD_STACK_LIMIT_MEMBER \
CYG_ADDRESS stack_ptr; /* pointer to saved state on stack */ \
CYG_ADDRWORD entry_point; /* main entry point (code pointer!) */ \
CYG_ADDRWORD entry_data; /* entry point argument */ \
CYG_HARDWARETHREAD_SAVED_CONTEXT_MEMBER
:
.
}
Am i the only one experiencing such problems?
Thanks for any suggestions.
regards, christoph
