Hello,


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?
