Clean shutdown of RT5350F?

[shish]

Hi!

I recently bought the RT5350F-OLinuXino-EVB and just started testing it. I came with OpenWrt Linux-3.18.19 pre-installed. (I have not altered it in any way.)

However, when I try to shut it off cleanly via the serial terminal using 'halt' or 'poweroff', it always reboots. No matter what arguments I use.

Anybody who knows how to do this? There is a little pause between the "System halted" message and the reboot, but to pull the power at that point seems a little "dangerous".

Log from using the 'halt' command:

At the least you can maybe interrupt U-Boot (hit a char such as space) and then power off.

Thanks John! Unfortunately, it seems that pressing space (or any other character) does nothing to stop the (re)boot?

[JohnS]

That's very odd - I've never been unable to interrupt uboot (it's why it has the menu).

Problem with your lead/etc?

As to why it doesn't halt... read (*) the code?  It's why source is useful

(*) and I suppose fix

It seems like this is a "feature" of OpenWRT:

https://forum.lede-project.org/t/poweroff-and-halt-commands-do-reboot-the-device-instead-of-halting/8971

https://bugs.openwrt.org/index.php?do=details&task_id=1400

And I believe it is the Watchdog that causes the reboot.

I'll solve this for the moment by hitting '4' during boot and enter "Boot Command Line Interface" and then power off:

Horrors - they ought to fix it (and it's a bug that can be fixed despite their pathetic response).

Oh well, 4 it is

You can power it off then.
