Hi all,
Sometimes, after boot-up, the system will be hang by splash and can't into android successfully. In that time, we got kernel messages and list below. By tracing omap_rproc_watchdog_isr(), it will set timer status to OMAP_TIMER_INT_OVERFLOW and rproc crash dump. We have no idea about this issue and what situation will trigger this ISR?
So far, we had tried http://review.omapzoom.org/#/c/21006/ and can't fix.
Could you give some suggestions how to fix this issue? Or some patches?
Thanks!
