Title:
[Mediatek] mt8195-demo: Fix hardware watchdog reset at boot time
around 10 sec.
Status in linux package in Ubuntu:
Incomplete
Status in lunar package in Ubuntu:
New
Bug description:
[Impact]
hardware reset during boot time.
[Fix]
Compare to generic kernel config for arm64
file: arch/arm64/configs/defconfig
The CONFIG_MEDIATEK_WATCHDOG should be enabled "built-in" in generic kernel
settings.
CONFIG_MEDIATEK_WATCHDOG=y
I've discovered that the module mtk_wdt.ko (CONFIG_MEDIATEK_WATCHDOG)
must be set as built-in to prevent the system from encountering a
hardware reset during the boot process. I've tried building it as a
module and installing it into initrd, and I've also attempted to set
softdep for it. However, I still can't find it being probed in the
initcall debug dump. The system also reboots around 10 seconds into
the boot time. After setting CONFIG_MEDIATEK_WATCHDOG=y, the hardware
reset issue was resolved and the system was able to boot into the
console.
[Other info]
effected kernel (5.19~latest)
ubuntu kernel for lunar, Kinetic, and Mantic.
