Hi, communty,

I have a question about i.MX6 Andrid BSP (jb4.2.2_1.1.0).

I want to know how to power off Android on MCIMX6Q-SDP.

I know the 2 methods, but I'm looking for other method because method "1" spends a lot of times to test rebooting many times and method "2" occurs a problem now on a custom board.

1. Push power button some seconds -> tap "Power off" -> tap "OK"

2. Use "reboot" command.

For your information, the following commands are not included in android.

poweroff, halt, shutdown

And the following commands a not works well.

busybox halt, busybox poweroff

Do you know other method to reboot i.MX6?

Best Regards,

Satoshi Shimoda

Hi Satoshi Shimoda,

     I also have the same problem. I can't use "reboot" command to reboot the machine.

The console will hang on "Restarting system" and nothing happened. I tried to take away the "watch dog" init function in board-XXX.c

Now, I can use "reboot" command to reboot occasionally ..... but didn't work every time.......

Could you reply to me?

And if you can, could you let me know a power off method which can finish I2C communication correctly.

Because the "a problem" I mentioned above seems be occurred uncorrect finishing of I2C communitcation.

Hi Yixing Kong,

I'm using "reboot" command because I have not found other command.

If there is no alternate command to reboot, please tell me it?

I checked with internal Android team, the reboot command is the right one to do system reset and there is no issue tested on i.mx6x SABRESD board.

Hi Qingrong Jiang,

Thank you for your reply.

> there is no issue tested on i.mx6x SABRESD board.

Yes, it is not wrong.

Actually, the issue seems depends on variability of individual chip characteristic whether the issue occurs or not occur.

Maybe, this issue occurs on a part of SABRESD, but does not occur on other SABRESD theoretically.

So it is difficult to reproduce the issue on i.MX6 SABRESD.

Hi YiFei WANG,


Thank you for your reply.

But sorry, "reboot" command I mentioned above includes any options, also "reboot -p".
