OMAP35xx DSP Device Driver for GPMC bus

Other Parts Discussed in Thread: OMAP3530, OMAP-L137

Hello,

Can you please help my customer?

 I am trying to come up to speed very quickly on OMAP35xx DSP development. Specifically, I need to develop a device driver on the DSP to pass data to and from our custom hardware via the GPMC bus. I have a Linux driver up and running that does this task on the ARM processor. I’m trying to come up to speed on the TI DSP architecture for device drivers and port that driver.

 I’ve downloaded the DSP/BIOS Driver Developer’s Guide which talks about the IOM interface and the Mini-Drivers. I know that the DDK is somewhat dated and now there is the concept of the PSP driver. I downloaded the PSP for the OMAP-L137/8 but I don’t know if that is completely applicable. I’d really like an example for the OMAP3530.

 I’d be grateful for any help you could provide.

Regards,

Andrea Ramos
