[ECOS] Serial device driver problem.

["Dennis Ehlin (ECS)" <Dennis dot Ehlin at ecs dot ericsson dot se>]

Hi,
 
I'm trying write a serial device to my ppc target, i'm using the generic 16x5x uart code.
I have the serial interrupts working and so on...
 
When i do a serial_read (located serial.c) everything seems to work ok, and  i get to the
cyg_drv_cond_wait(&cbuf->wait) line and it stops there to wait for the cbuf->wait signal. ok.
 
Then i generate a serial receive interrupt and the serial_rcv_char function is called,
which sends the cbuf->wait signal with the line cyg_drv_cond_signal(&cbuf->wait).
 
But nothing happends?, the cyg_drv_cond_wait(&cbuf->wait) never continues, as if it never gets the
signal.
 
I suppose there's alot of things that can go wrong, but I dont have a clue of what is happening there.
Does anyone know of something that could cause this ?
 
(I use the serial_echo test to test this)
