ASUS Tinker Board Reboot


TonyMac32

Recommended Posts

*Updated 7-23*

 

~~All kernels should be fixed at this point, Legacy, Next, and Dev.~~

 

The ASUS Tinker Board has a big problem with rebooting properly, centered around the SD card power supplies.  Upon issuing a shutdown request, the kernel is turning everything off , including the vmmc regulator.  To make matters worse, vqmmc is set to 1.8 Volts if you use a UHS SD card, and the kernel is not switching it back to 3.3 volts before rebooting, which is required if the Rockchip boot ROM is to communicate with the device.  The result is a hung board in MaskROM mode.

 

For the Default kernel (4.4), a patch was carried over from the vendor software (quite literally tagged as "HACK" which added a shutdown routine to the rk mmc driver.  It powers vmmc back up, switches vqmmc back to 3.3 volts, then delays for 20 uS or so.  It works on default.

  • 7-22:  Need to add fix for " echo b > /proc/sysrq-trigger "  ETA:  7-22 or 7-23
  • 7-22:  Adding device check to make certain there are no complications with the MiQi.  Concurrent with sysrq fiq.  Complete and uploaded.

 

For Next/Dev kernels, however, it does not work.  I don't know the full system that well, so I can't comment as to why just yet.  It is also important to note that testing the patch on kernel 4.11/4.12 resulted in a MiQi crash on reboot, wheras I've had confirmed this doesn't appear to be an issue on 4.4.

  • 7-22: It was determined a day or so ago that the issue was the mmc not being powered down before the hack happened.  Now that is commanded. 
  • 7-22: Initial patch broke MiQi, myself and @Myy worked today on figuring it out, trading kernels and patches.  We thought it a good idea to use the device tree platform to discriminate.  Fix is now known, adapting patches and moving them from Dev to Next.  Implemented
  • 7-23:  Rockchip-DEV is now kernel 4.13, reboot patch tested and works.

 

Any expertise in this area would be welcome, I'll update this post as things go on.

When looking for 'reboot' hooks on the platform_driver structure, I stumbled into this :

 

https://groups.google.com/forum/?_escaped_fragment_=topic/linux.kernel/QFt8UL8WgxQ#!topic/linux.kernel/QFt8UL8WgxQ

 

I don't know if that could be related to this issue. It talks about setting up special registers on reboot, to tell the Rockchip boot system which mode should be used for the next cycle.

Hi @Myy,

I would like to test, but compiling and such is new to me.

I saw this in another forum:

Quote

The kernel 4.12.0, with Mali r17p0 drivers and various RK3288 patches
https://github.com/Miouyouyou/MyyQi/releases

This so called release is not an image but all you need to create a Kernel, right ?

 

I saw your posting with:

Quote

If you use the Tinkering branch, here:  https://github.com/Miouyouyou/MyyQi/tree/Tinkering
Add the following boot option to your boot loader : rockchip_tinkerrebootfix=on
Then try to get a serial output, shutdown the machine and paste the serial output here, directly or through a pastebin/ghostbin link.
This will help me understand what's happening during the shutdown phase, and maybe resolve the issue altogether.


For someone like me who knows quite a bit but not as much as you do :)
Can or must I compile this on my x86 PC and burn it on the SDcard or  ..which is the correct way to proceed?

Hmm, or is this just the Kernel and DeviceTree that need to be compiled and copied into an armbian 4.12 as example?

It's both actually !

 

In the boot, lib and usr directories for the release, you'll have the appropriate files you need to copy in your system's /boot, /usr and /lib directories.

That said, I haven't generate any release for the Tinkering branch, so you'll have to clone it through Git. Basically, you could do something like this to generate a kernel archive that you can unpack elsewhere :

git clone -b Tinkering --depth 1 https://github.com/Miouyouyou/MyyQi
cd MyyQi
tar cJpvf kernel.tar.xz boot lib usr

 

Then you can copy the kernel.tar.xz in the MyyQi folder on your RK3288 board, unpack it in tmp, mount your /boot partition if it's on a specific partition, and copy the each folder like this :

tar xJpvf kernel.tar.xz
cp -r usr/* /usr/
cp -r lib/* /lib/

Then copy the zImage in boot/ in your boot partition, along with the rk3288-tinker.dtb or rk3288-miniarm.dtb. On Armbian, DTB files should be placed in /boot/dtb .

You might also have to play with your bootloader, in order to boot this specific image.

 

If you know what you're doing, you could just copy the kernel.tar.xz in / and unpack it directly, though.

 

I'll try to make this clearer for the next release.

 

Now, concerning the kernel compilation, you just need to copy the compilation script somewhere, edit the

export CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi-

So that it matches your cross-compiler prefix. If you don't know what is a cross-compiler prefix, it's basically what's prefixed to cross-compiling binaries names. In my case, the cross-compiling gcc is actually : armv7a-hardfloat-linux-gnueabi-gcc and the cross-compiling ld is actually : armv7a-hardfloat-linux-gnueabi-ld , etc...

Well, I guess it already fits as it is - so there is no need for me to compile the Kernel?

Burned the SDcard with armbian 4.12 nightly (unfortunately desktop image, quite large).

What I did:

git clone -b Tinkering --depth 1 https://github.com/Miouyouyou/MyyQi
cd MyyQi
tar cJpvf kernel.tar.xz boot lib usr

Followed by:
sudo dolphin
create a folder on the SDcard (home directory)
copy the kernel.tar.xz into that.

Connect the UART cable.
Insert the SDcard in tinker board, Power.

Boot the tinker board (reboot doesn't work so while extending the SDcard it 'dies').
Power off - Power on - login as root.

cd /home/tido/
Unpack all the files: tar xJpvf kernel.tar.xz

open a second SSH look into the folder:

cd /usr/
ls -la

copy the files

cp -r usr/* /usr/
cp -r lib/* /lib/
in the second SSH 
cd /boot
ls -la
cd /home/tido/boot/
ls -la
cp -r zImage /boot/
cp -r rk3288-tinker.dtb /boot/dtb/

Armbian uses currently not the dtb called: tinker. Instead rk3288-miniarm.dtb rk3288-miqi.dtb.
cp -r rk3288-miniarm.dtb /boot/dtb/
cp -r rk3288-miqi.dtb

It is actually an easy instruction for everyone :)

reboot - now I can login

Is this already in the file ? 

Add the following boot option to your boot loader : rockchip_tinkerrebootfix=on

Glad you made it !

 

The option is not automatically enabled though. You'll have to edit the right bootloader configuration file. It should be /boot/extlinux.conf if I'm not mistaken (I've kinda butchered my ARMbian installation, so I'm not totally sure).

 

So edit the right bootloader configuration file in order to add

rockchip_tinkerrebootfix=on

to the command line.

 

If you're using an extlinux.conf file, add it to the end of the the 'append' line.

 

Now, the thing is, the first dmesg included in the armhwinfo.log give me some idea of what's going on, but I really need the messages output by the kernel, during the shutdown phase. The same ones displayed by dmesg.  If you can configure journald somehow to be more verbose and show kernel messages, this might do the trick.

 

The information I need to get is whether the shutdown fix gets executed or not, and whether the suspend system is disabling the power sent to the MMC hardware before letting the drivers execute the .shutdown phase.

I guess armbian doing the boot in a different way ?  Shall I edit the file according to this?

 

So I have just changed from 1 to 7

verbosity=7
fdt_file=rk3288-miniarm.dtb
rootdev=UUID=e8d35e52-8539-441f-be02-6161addf3bd3
rootfstype=ext4

armbianEnv.txt (END)

================================

# This is /boot/boot.cmd
#

setenv rootdev "/dev/mmcblk0p1"
setenv fdt_file "rk3288-miqi.dtb"
setenv ramdisk_addr_r "0x21000000"
setenv console "ttyS2,115200n8"
setenv verbosity "1"

itest.b ${devnum} == 0 && echo "U-boot loaded from SD"
itest.b ${devnum} == 1 && echo "U-boot loaded from eMMC"

if load ${devtype} ${devnum}:1 ${ramdisk_addr_r} /boot/armbianEnv.txt || load ${devtype} ${devnum}:1 ${ramdisk_addr_r} armbianEnv.txt; then
        env import -t ${ramdisk_addr_r} ${filesize}
fi

setenv bootargs "consoleblank=0 scandelay root=${rootdev} rw console=${console} rootfstype=ext4 loglevel=${verbosity} rootwait ${extraargs}"

# mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
boot.cmd (END)

as it refers above to: rk3288-miniarm I will copy that one over as well from your source.

cp -r rk3288-miniarm.dtb /boot/dtb/

/var/log/armhwinfo.log has been uploaded to http://sprunge.us/CPIV

Edited by Tido
added hw log, added boot.cmd

You might have to append it to at the end of the setenv bootargs command of the boot.cmd command, and then run

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

again.

 

Note that whether you use rk3288-miniarm.dtb or rk3288-tinker.dtb, be sure to adapt the fdt_file variable in consequence. Currently it seems to refer to the MiQi dtb. I don't know which one has priority though. the armbianEnv one or the boot.cmd one.

23 hours ago, Myy said:

I really need the messages output by the kernel, during the shutdown phase. The same ones displayed by dmesg.  If you can configure journald somehow to be more verbose and show kernel messages, this might do the trick.

I searched and came across this

1.  How to get kernel boot log with journalctl?

I guess this is what we already have I have done:  journalctl -k > dmesg.log

and this

2.  Diagnosing Shutdown Problems

done this but there is no file after shutdown, maybe I have to change the folder?

#!/bin/sh
mount -o remount,rw /
dmesg > /shutdown-log.txt
mount -o remount,ro /

 

Any suggestion is welcome

If you have an UART cable, it might easier to connect it to the Tinkerboard, open a serial console on the host and, then, power on the Tinkerboard by plugging the micro-USB cable on.

The serial console will get all the messages in real time.

The issue with writing on the SD card is that, the reboot issue is related to the MMC driver lowering the voltage of the SD/MMC hardware during the shutdown phase, to a point that it does not get up again (for reasons I don't understand, since I guess that it gets up automatically during a cold boot...). So, that might be the reason why you're getting issues with writing the shutdown messages to the filesystem.

That said, I wonder if that reboot issue also occurs with official Android images and what happen if you tell the system to reboot in recovery mode.

This is easy

[  616.164534] reboot: Restarting system

 

 

 

and in one of the posts above (unfortunately they have no numbers) you find the shutdown from UART without your patch.

That said, I wonder if that reboot issue also occurs with official Android images and what happen if you tell the system to reboot in recovery mode.

I downloaded it a while ago, but never installed it.

Beside that it might be also interesting how they solved it on Chromebooks?

Well, it is a Tinkerboard specific issue, so I'm unsure whether Chromebooks had the same exact issue. I have a RK3288 MiQi board which does not present such issues.

 

Anyway, concerning the logs, it looks like the system is not outputting the kernel messages directly on the console, except when journald dies I guess. The only kernel message visible being :

[  616.164534] reboot: Restarting system

IIRC Armbian is already configured to output kernel messages to the console displayed with ALT+F12, so I'll try to look around, see if I can find how to configure systemd to output the kernel messages on the serial console.

Meanwhile, you can try to change ttyS2 to ttyS1 in boot.cmd, rerun the commands shown in boot.cmd comments and give it a try.

what happend sounds like this -> squelches the Kernel so I turned it back to ttyS2.

The red LED is on when I do init 6, if I do init 0 the LED is off.

from 1 to 7

setenv verbosity "7"

 

If specified, overrides both the kernel command line setting systemd.show_status= (see below) and the configuration

How to get systemd boot messages on serial console and screen?

I am just connected headless, is this helpful if a screen is connected?  I guess it would fly by way too fast anyway.

No, a screen won't be of any use, unless you try to record the screen with a 60fps+ video camera. That's insane.

 

Instead, could you paste the content of :

cat /proc/cmdline

In order to know if the bootloader gets configured correctly or not.

Thank you @Myy, I compiled the fix into a Dev kernel, but haven't had opportunity to test yet, I'll be doing that in around 6-8 hours after work.  This is where I complain about wishing I knew more so we could simply not shut off the vmmc and set vqmmc to the proper level without it being an amazingly sketchy hack.

 

As for the commercial RK3288 devices on the market:. They boot from SPI and/or eMMC, not from SD.  The SD is handled as a peripheral drive, not as a boot drive by the kernel.

Indeed. No virtual platform representing this device really makes things difficult. The schematics won't lead us far in knowing what's going on exactly. And systemd seems to love shunting kernel messages logging on the serial console, making things harder to analyze. And contrary to what the StackOverflow guys said, not putting any loglevel on the command line makes no difference when it comes to not displaying kernel messages, beside the emergency ones, on the serial console.

Maybe the journald developers thought that people would like to use serial consoles every day, because, you know, DVI and HDMI are so overrated.

 

Well, the last issue can be alleviated by just spouting log messages with printk using the "emergency" log level. It's ugly but everything is ugly on test kernels anyway. I really need to investigate this issue however.

 

If I have some time this week, I'll see if I can force the Rockchip system to reboot in various modes, and test if one of this mode just resolve the issue automagically.

 

Anyway, I'm not in a hurry. Take your time. :)

AFAIK it's not related to systemd. Some loglevel overrides come from Debian/ubuntu default, i.e. on Xenial it's caused by /etc/sysctl.d/10-console-messages.conf (added by the "procps" package), and lack of kernel messages on any console can be caused by multiple console= defines on the kernel command line, since without explicit forwarding (i.e. by journald) kernel will print its boot log only on one console.

I missed the target then, I guess. My cmdline is

earlyprintk console=ttyS2,115200n8 rw root=/dev/mmcblk1p5 rootfstype=ext4 init=/sbin/init

Which is the same I used on my Gentoo system, however I got the kernel messages on Gentoo.

 

So, yeah, that might be 10-console-messages.conf

 

# the following stops low-level messages on console
kernel.printk = 4 4 1 7

 

I guess that setting this to 7 4 1 7 will allow kernel messages on... the console ? Like every console ?

 

I'll give it a try.

Yeah, that seems to do the trick, thanks for the information.

 

So, in order to display all the kernel messages on the serial console :

  • open up /etc/sysctl/10-console-messages.conf
  • replace kernel.printk values with 7 4 1 7
  • Save the file, reboot and enjoy a serial console acting like a serial console !

To see even the debug messages, you might need to set it up to 8 4 1 7.

 

The meaning of the values are defined in syslog(2)

I used

echo b > /proc/sysrq-trigger

to trigger reboot on 4.12.2 with the ugly hack installed, and it worked.  Without the hack it does not.  Let me see if I can apply it to the normal reboot process.

Emergency reboot.  I haven't applied those to the other shutdown path yet.  I was researching the shutdown process to see if a cleaner method could be conceived of...  I need to save up my pocket change and get an oscilloscope so I can do some better hardware debugging.  So I'll get back to you in 5 years or so... :-P

By that time, ASUS will already be using 4.9 kernels !

 

That said, if

echo b > /proc/sysrq-trigger

 

works, one workaround will be to put this as the last action before rebooting. :lol:

*EDIT*  I'm holding "Dev" back at 4.12 until we get this reboot tested.  @Igor, if you can try it out on your MiQi and make sure there weren't any unexpected collateral damages.  I don't know who else besides @Myy has one.

 

"DEV" is now 4.13 and is having build errors.  I'm going to strip some patches and see if that takes care of it.  Meanwhile, the patch will work on "Rockchip Next" for anyone able to test it's effect on MiQi.  Once we verify MiQi is OK, I can stuff it in there and let it go free.

 

I added the "mmc_power_off()" call to the platform shutdown hack, to make certain the card was "dead" before restarting the supply and resetting 3.3Volts and, well...

 

It works!  So I will put the patch into Dev, if MiQi owners can test if it breaks then we'll have to do something else, decided by the build system wizards.  ;-)

In armbian it is: cd /etc/sysctl.d/ && ls -la

nano 10-console-messages.conf

# the following stops low-level messages on console
#kernel.printk = 4 4 1 7
kernel.printk = 7 4 1 7

 

I have added this to all the steps I have done above, but there is not more text, while rebooting even less:

root@tinkerboard:~# init 6
[   33.846618] reboot: Restarting system
