DSP/BIOS: SWI_post doesn't work

Hi all!!

I'm working with a C6727 in the Professional Audio Development
Kit(PADK) created by Lyrtech. I need to post a SWI to process the
data adcquired in a HWI. So I've defined the SWI in the DSP/BIOS
Graphic Tool and, along the execution, I'm using a periodic task
(PRD) to test a flag and to post the SWI. The problem is that this
doesn't work. I put a breakpoint in the SWI_post instruction and
another inside the SWI routine, and the first is achieved, but the
second isn't.

After that I tried to create the SWI using the API instructions,
creating the parameters structure and the SWI, but when I try to
execute the project, the program stops just after the main function.

Can you help me? Does anyone know why is this happening?

I did something similar before in the DSK6713 and it worked, but in
this case it doesn't.

Thanks for advance!

Pedro

Did you set the mailbox of that SWI in the configuration tool? (probably a stupid question)
