Hi All, I was wondering whether it is possible to keep the Cortex M3 cores running while the OMAP processor is suspended.
My testing environment was simple: I used Pandaboard (OMAP4430) and kernel 2.6.35. I wrote an M3 program to toggle one GPIO pin (which drives a LED). As long as the M3 program is running, the LED will blink. On the kernel side, I tried to change the suspend functions in arch/arm/mach-omap2/pm44xx.c. I set the states of core_pwrdm and l4per_pwrdm to ON, right before the system suspends. However, when the system was suspended (omap4_pm_suspend() was invoked), the LED stopped to blink. I think the M3 cores were powered off then. Did I miss anything? I'll really appreciate any input. Thanks! -Felix -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
