Hello,
I'm trying to bring up eCos on an ARM9 board, the starting point I
have is a port for Redboot but I would like to use the full feature
set of eCos. I have put together a configuration which I can program
to the board and have basic I/O over serial.
The main entry point for my code 'cyg_start' runs as expected but the
thread I create does not start. I enabled debug trace and the first
assert I get is "ASSERT FAIL: <2>mlqueue.cxx[265]void
Cyg_Scheduler_Implementation::add_thread() Idle thread vanished!!!"
Can anyone tell me why I would get the ASSERT above?
thanks,
Brendan.
========= code ===========
void cyg_start(void)
{
unsigned cyg_start_count = 0;
diag_printf("Hello from cyg_start: #%u\n", cyg_start_count++);
cyg_thread_create(1, testthd_main, (cyg_addrword_t) 0, "testthd",
(void *)stack[0], STACKSIZE, &thread[0], &thread_obj[0]);
cyg_thread_resume(thread[0]);
for(;;)
{
cyg_thread_delay (100);
}
}
static void testthd_main (CYG_ADDRESS data)
{
unsigned int Count = 0;
for (;;)
{
diag_printf ("testthd_main:: %10u\n", Count++);
cyg_thread_delay (100);
}
}
