seems there are two RTC on Jetson xavier -nx.
ls -l /dev/rtc*:
/dev/rtc -> rtc1 /dev/rtc0 /dev/rtc1
system log show that RTC0 was
max77620-rtc and RTC1 was
I connect a coin battery on Jetson xavier - NX for RTC1, after set system time and disable timesyncd service. use
hwclock -w -f /dev/rtc1, the system time can sync to RTC. but if I use
hwclock -w without
-f options, it seems hwclock did’t work.
I want to use tegra-rtc as default RTC by disable max77620-rtc by remove node like 'RTC0 ', but I didn’t found any node that named “max77686-rtc” or “max77620-rtc”,what should I do to.
BWT, if had disabled RTC0 or remove RTC0 from device tree, can I use hwclock without
-f options to set RTC time ?.
