What processor are you using? (So I can point you to the correct software)

DSP/BIOS Device Driver Developer's Guide: http://focus.ti.com/lit/ug/spru616/spru616.pdf

For DSP/BIOS application examples please see:

C:\CCStudio_v3.3\bios_5_33_05\packages\ti\bios\examples

It took me a while to get my head around the using/creating device drivers. I think the documentation is outdated and confusing.

In the end I did what it said in "Developing a Mini-Driver Step-by-Step" in spru616 and successfully created a SRIO IOM device driver for the C6455. I connected the device driver to a stream. I believe, but note I'm not a TI employee or expert in this, that IOM is latest and recommended type of device driver for DSP/BIOS V5.

The main cause of confusion is that spru616 talks mainly about "old style" device drivers and it took me a while to realise that I had to ignore most of spru616. Lots of other documents talk about device drivers and point in the wrong direction i.e. they are out of date.

I believe you do not need a DDK, DDK are old technology. Again note, I'm using a C6455 and it might well be different for other devices.

HTH,

Matt

Hi MattB,

All the software for the C6455 is not based on DSP/BIOS drivers (PSP/DDK), it is based on CSL (chip support library):

http://focus.ti.com/docs/toolsw/folders/print/sprc234.html

So I would suggest for you to use the software provided. If you want to use DSP/BIOS with csl, please see:

Yes I know TI haven't provided a DSP/BIOS PSP for the C6455 hence I've had to create my own IOM driver for SRIO.

Mariana said:

TI have provided a C6455 CSL but I don't think much of the functional layer. I'm using the register layer in my IOM driver.

The C6455 examples and functional layer helped me get started.

Er, what software is provided for the C6455 apart from the CSL?

Mariana said:

I am using DSP/BIOS with the CSL and I had to create my own IOM driver so that I could use DSP/BIOS streams with SRIO on C6455.

If there is an alternative to this then please explain.

I was trying to help Satheesh find the documentation on DSP/BIOS device drivers because TI don't provide them for all devices.

Regards,

Matt

Oh, I know about the MQT for SRIO Messages and we will probably use this but we are also using SRIO Direct I/O for which (as far as I can tell) there is no software.
