I'm using the i.MX6 DL.
When I first time test the custom board,
I can set the system time and sync with hwclock by hwclock --systohc.
But after changed some of H/W peripherals,and making a new custom board,
hwclock command is not working.
first, I set the system time by
#date "2018-08-13 13:33:11"
Then I can check the changed system time.
But for the saving to rtc, input the below message,
# hwclock --systohc
Then nothing changed and there is no reaction.
It looks there is no response so it just wait some response..
Because kernel & rootfs is not changed but only my custom board's some part was changed,
So I thinking that some part making this problem.
Do you have any idea of this??
What can making this problem?
