SYS/BIOS + CSL

Angelo Bonifacio64136

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

in the TI SYS/BIOS Real-time Operating System v6.x User’s Guide is written:

Hwis must not use the Chip Support Library (CSL) for the target. Instead, see
Chapter 6 for a description of Hardware Abstraction Layer APIs.

This means that inside HWI interrupt service routine I cannot use CSL function like ???

CSL_aif2GetHwStatus(gAif2,CSL_AIF2_QUERY_AT_RAD_SYMBOL_COUNT,&symb);

Best Regards,

Angelo

Hello Angelo,

I don't have familiarity with CSL, but the Hardware Abstraction Layer section in the User's Guide elaborates on this subject a little more:

The most recent releases of CSL (3.0 or above) are designed for use in applications that do not use SYS/BIOS. Some of their services are not compatible with SYS/BIOS. Usage of CSL interrupt, cache, and timer functions and SYS/BIOS in the same application should be avoided since this combination is known to result in complex interrupt-related debugging problems.

So I would definitely advise against any CSL functions that involve interrupt, cache, and timers, but I would have to check with a more knowledgeable source to see if this applies to all CSL functions.

Hi Whitney,
thank you for your answer; if you have more detailed info about CSL+SYS/BIOS please update this topic.

I spoke to someone else on the subject, and it sounds like functions that don't affect interrupts, timers, and cache should be safe. However, in general, it isn't recommended to use CSL APIs with BIOS, so use them at your own risk.

If CSL cannot be used with Sys/BIOS then what is the recommended way to configure peripherals like McBSP, DMAC and EMIF?

I'm not sure which hardware platform you're on, but the BIOSPSP drivers product may be what you're looking for.

You can have a look at that here:

There are 2 platforms I am working on: TMS320DM816x and TMS320F28335. Can I use the same BIOSPSP or do I need something else?

Hi Eruan Abdul Razak,

For the 28335, there is no PSP driver package. But, there is a product called ControlSuite that should be helpful to you:

For DM816x, I'll ask for someone else to help, as I'm not familiar with that.
