DSP/BIOS to SYS/BIOS conversion

Divya6781

Hello,

What are the equivalent macros in bios6 for "SYS_OK", "SYS_EALLOC", "SYS_EFREE",..... (defined in sys.h)?

Also what is the equivalent of HOOK_id in bios6?

I have read the dsp/bios to sys/bios migration guide.  But could not find the solution to the above questions.  Is there any other document which covers the topic in greater depth?

Thanks.

Regards,

Divya

    Divya,

    There are no "global" error codes defined in SYS/BIOS 6.x, so there is not an equivalent for the SYS_E* defines in sys.h. Each module defines its own errors.

    The way hook functions are handled has been changed so that a Hook_Id is no longer needed. There are a variety of hook points during the startup sequence (see Section 3.1 of SYS/BIOS User's Guide) and there are hook points for Task, Swi, and Hwi modules (See Table 3.1 in the user's guide).

    If there is a specific kind of behavior/functionality that you are trying to port, perhaps you could give an example and I could give more specific advice.

    Thanks Mark.  I have just started porting my code and will let you know if there are any issues.
