Omap 4430 Watchdog timer driver

Salman Khalid1

Prodigy 20 points

Hi,

I am learning device driver development and I want to write watchdog driver for my pandaboard running linux but I have no idea where to start. I have written linux kernel modules so I know how to write a basic character driver but I am not able to find any reference material for writing watchdog timer device driver. Please point me in the right direction and if possible give me links to concerned reference material.

Hi,

If you are using OMAP 4 pandaboard with OMAP4430 processor you can find the Watchdog information in the public TRM document found here

http://www.ti.com/lsds/ti/omap-applications-processors/technical-documents.page?viewType=mostuseful&rootFamilyId=601&familyId=2937&docCategoryId=6

or http://www.ti.com/product/OMAP4430

The document is OMAP4430 ES2.x Technical Reference Manual [Public] Version AN (Rev. AN)

In chapter 22.3 all features and registers of Watchdog timers are described.

Hope this helps.
