Re: DSP/BIOS TSK restart

I would put a
while (1) {
SEM_pend(&some_hwi_sem);
code
}
loop in the task, then

SEM_post(&some_hwi_sem);

from within the HWI.

Subject: [c6x] DSP/BIOS TSK restart

Dear all,
I want to restart my task (run from the very begining of my task) after rcv some
HWI when my task is running.

Which API should I use? Or I have to delete in my HWI ISR and creat the same
task again?
I am new to DSP/BIOS , and I use DM3730 with BIOS V5 under CCS V4.2.

Best regards! Start a New Thread

Dear Andrew,
If INTR comes when task is processing(in "code" part), it will premmpt the task, after HWI finish, the task will continue processing.
But I want it run from the very beginning of the task(may be "while(1)" or "SEM_pend(&some_hwi_sem)").
Is it possible?
Best regards!

It sounds like you have an irregular (non-periodic) interrupt, and when you get one you want to restart your
processing, even if you were already in the middle of it. If that's the case then I might suggest finding a way to
use TSK_create() and TSK_delete(). Here is a thread where they seemed to be doing something similar:

I would guess your include path(s) are not set up correctly.

Krishnan-

> errors on the project of audio codec may help me.

First, can you make an original post and subject-line? Your question has nothing to do with BIOS and task restart.

Second, it seems like your project implodes at line 24 of audiocodec.c, but for some reason you didn't think it was
important to show that line.

Suggest to make your own post, and show lines 22-25 of audiocodec.c.

rani,

did you remember to include the audiocodec.h file?

can you post the audiocodec.c file, lines 20 through 32?

Are the header, library, and source code files all for the same version of the DSP?

The error messages read like the compiler is thinking the macros are actually
function calls.
The inclusion of the appropriate .h file(s) should correct those compile problems.
