TMS320VC5510A: DSP/BIOS IRQ_Clear() Function not present

Part Number: TMS320VC5510A

I am porting a project from CCS3.3(DSP/BIOSv5.31.02[but started many revisions before this]) to CCS10.2(DSP/BIOSv5.42.02.10). I am currently working on the functions related to the handling the c55xx processor interrupts. I have been able to translate most of the differences but have been unable to determine a new/equivalent function call for the old codes IRQ_Clear() function. Can you provide any assistance for this?

    Hi,

    I don't see IRQ_clear() mentioned in the the following docs packaged with C5000 DSP/BIOS 5.31:

    • API Reference Guide
    • DSP/BIOS User's Guide

    Looking through the BIOS 5.31.02 installed content, I only see one reference to this function:

    packages/ti/psl/examples/psl_timer/timer.c:113:   IRQ_clear(eventId0);

    My guess is this is a CSL function, not a DSP/BIOS function. In fact, I see a prototype for this function in the latest CSL which supports C5510A:
