> did you try twl4030_wdt instead of omap_wdt? Hi Enrico,
Last night I went searching around for a fix on the same watchdog problem Steve was having, but this time on a BeagleBoard XM Rev. C., using the 37xx chip. Using the twl4030_wdt driver instead of omap_wdt driver succeeded in rebooting the system, but with these issues: 1. When running the watchdog from a C program (e.g. using the example code from http://embeddedfreak.wordpress.com/2010/08/23/howto-use-linux-watchdog/), the program executable itself has been changed such that its 0 bytes after the reboot. 2. It's impossible to get the cause of the last power cycle via the watchdog. i.e. The WDIOC_GETBOOTSTATUS is handled differently in twl4030_wdt vs. omap_wdt, the latter of which relies on omap_prcm_get_reset_sources(). So while the twl4030_wdt driver gets me 90% there, I still need the ability to detect a watchdog-causes reset vs. any other reset. So, is there a patch coming for the omap_wdt driver for 37xx boards?
