11:30 <austriancoder> should it be possible to use main_rti0 or main_rti1 (as watchdog) to trigger a system reset on am642?

17:12 <NishanthMenon> austriancoder: yes - but esm needs to be programmed on all k3 devices

18:33 <austriancoder> NishanthMenon: I already thought that might needed. I have not found any Linux driver in TI's kernel repo.

18:33 <NishanthMenon> hmmm.. i know we did for upstream j721e .. need to confirm from Hari on the integration aspects for am64

18:34 <NishanthMenon> drivers/misc/k3_esm.c

18:34 <austriancoder> I got the rti_wdt driver loading on am64 with this https://lore.kernel.org/linux-arm-kernel/20220111134552.800704-1-christian.gmeiner@gmail.com/T/

18:35 <NishanthMenon> yup - that is one part.. esm needs to be setup in u-boot for it to reboot the system

18:39 <austriancoder> funny.. I did not found the esm driver when I looked in U-Boot and kernel sources.

18:39 <austriancoder> Thanks for the hint

18:39 <austriancoder> Looks like I could get the wdt working soon

18:50 <NishanthMenon> i need to look a little deeper.. Hari had gotten it to work on the follow on chip of am64 last week. but as i recollect, the esm_main needs to be routed to esm_mcu and result in resetstatz assertion. i need to talk to hari on what exactly he had programmed

19:00 <austriancoder> NishanthMenon: that would be great!
