Suspend button only works once

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin NX

• Hardware Platform (Jetson / GPU)
Orin NX
• JetPack Version
5.1.1-b56
R35 (release), REVISION: 3.1
• Carrier board
DSBOARD-ORNXS from forecr.io

Situation:
I’ve connected a button between the front panel PWR_BTN and GND.
If I short press the button, the system suspends.
If I press it again, the system wakes.
No further presses have an effect.

Troubleshooting:
I checked
sudo cat /sys/kernel/debug/wakeup_sources
At fresh bootup, the gpio-keys show 0 in both active_count and event_count.
After a suspend/wake-up cycle, both of those show the value 4.
An additional button press (which does’t suspend the system) and the values change to 6.

sudo dmesg | grep -i "gpio\|suspend\|wakeup"
Shows only a single suspend/wake-up cycle.
[ 793.883014] PM: suspend entry (deep)
[ 796.175515] PM: suspend exit

The carrier board provider recommended forcing a value change at this address.
$ sudo busybox devmem 0x0c2f1080 32 0x000000ED
They said that they had gotten that command from Nvidia developers.

In that particular case the value had changed to 0x00000001

This did not help and is not in my case (perhaps a Jetson version difference?)
In fact, the value of 0x0c2f1080 remains 0x000000ED at startup and through every subsequent step.

The carrier board provider suggested trying a software suspend
$ sudo systemctl suspend

This works.
I can then wake the system with the button.
However, I can still not use the button to go back to suspend.

Any advice?

Long pressing the button (approx. 6 seconds) will force halt the system.
It will not recover on button press.
It will not recover by means of disconnecting/connecting power.
I have to disconnect power, wait for a while, then reconnect so that the Jetson auto-starts.
This in itself is an acceptable behavior for now.

During further troubleshooting I noticed similar behavior on other occasions.
ie. the following commands followed by a short button press…

sudo systemctl restart gdm
sudo systemctl isolate multi-user.target

… both resulted in a hard system halt approx. 6 seconds later.

Which GPIO is in use for that button you are talking about?

5

The front panel connector on the carrier board has several pins.

1. PWR_BTN
2. GND
3. RESET
4. GND
5. RECOVERY
6. GND

I am using pins 1 and 2 there.

As far as I can tell, the PWR_BTN pin maps onto pin gpio-343 (PEE.04) below:

By default it is not exported for use as a GPIO.

On a side-note, I also tried disabling wake-on-lan
sudo ethtool -s eth0 wol d
That didn’t help either.

7

Ok. To clarify the situation first

After the situation happened, are you saying that if you press the power button again, the GUI won’t trigger the prompt again to ask you whether you want to suspend or power down?

8

I am using the Jetson via terminal ssh only.
The first button-press triggers the first suspend that happens immediately without any prompts/questions.
Another button-press wakes the system.
The second button-press does not suspend the system, and I do not see any prompts/questions, but then again, I am in a terminal session.

echo $XDG_SESSION_TYPE
tty

This indicates that the system is running in a non-graphical mode.
Would the system be prompting prior to a suspend in that case?

9

Let’s check if the functionality of that pin is still fine.

Please check /proc/interrupts and see if that gpio still got interrupt number increase after you press the button after the NG case happened.

10

I am not sure what I’m looking for there.
I don’t see a mention of that pin number.

cat /proc/interrupts before first suspend:

It is mentioned as “power-key” as 316 in the result you shared.

After your first wake, you can see that there are 4 interrupts on CPU0

316: 4 0 0 0 0 0 0 0 gpio 27 Edge power-key

What I want to know now is whether that GPIO still gives you more interrupt after your wake. As you said that pin seems not able to work anymore after your first wake. Please check if press power-key still trigger any new interrupts in that line.

12

Yes, more interrupts are triggered.
It increments by two (probably rising and falling edge of button) for every subseqent attempted suspension.

316: 8 0 0 0 0 0 0 0 gpio 27 Edge power-key

Looks like this is different issue from previous one shared previously to modify register 0x0c2f1080.

Is it possible to do the same test on rel-35.6?

14

To summarize, I had the suspend problem on JP5.1.1 (L4T 35.3.1).
You recommended switching to JP5.1.4 (LT 35.6.0).
That is not among the JP versions that have been tested our software on.
Instead, I chose to install JP6.0 (L4T 36.3).

Checking now…

15

It seemed to work at first.:
At bootup the address sudo busybox devmem 0x0c2f1080 contains 0x000000ED
Further suspend/wake cycles worked fine.

Later, after some more installs and reboots, the suspend button stopped working.
There are still interrupts happening, but now on pin 226, which is a different pin than before:

I disabled everything incrontab -e and sudo crontab -e
Also looked through .bashrc to see if there was anything obvious interfering there.
Tried disconnecting all I2C’s, ethernet, USB etc and reboot.
Checked that gsettings get org.gnome.settings-daemon.plugins.power power-button-action returned 'suspend'
Didn’t help.

Then suddenly suspend/wake worked for a few minutes.
After another reboot, it stopped working again.

16

Now, 10-15 minutes after boot, the suspend/wake starts working again.
At this point sudo busybox devmem 0x0c2f1080 had changed to 0x0000004D
Did another reboot.
At startup sudo busybox devmem 0x0c2f1080 was 0x000000ED
I forced the value
sudo busybox devmem 0x0c2f1080 32 0x0000004D
That seems to help sometimes, but not shortly after fresh reboot.

Which Jetpack release are you trying to use here for that latest comment?

Basically we won’t directly check on a old release version like rel-35.3.1. For example, new release might already fix that. For such case, checking old release does not help.

If there is a bug, you should check with latest version first. For rel-35, that is rel-35.6. For rel-36, that is rel-36.4.3.

Also, no one else ever reported this issue on latest version except you. Thus, we need to clarify the situation first.

18

Currently, the Jetson has JP6.0 (L4T 36.3).
What you are saying is I need to upgrade to JP6.2 (L4T 36.4.3) or downgrade to JP5.1.4 (L4T 35.6.0)?

19

Hi,

Just to clarify the situation because I don’t understand what is the exact scenario from your comment.

What is the exact release version that you are using in below comment?

Also, does writing the register value from 0xED to 0x4D help or not? If it helps, then I believe it is still same as old post mentioned and latest rel-35.6 /rel-36.4.3 both have the official fix.

If you don’t know what is the exact debug logic here for that register thing, let me explain below:

For some old jetpack release, we noticed the GPIO setting for interrupt would be disabled after doing SC7/suspend. If interrupt got disabled, you won’t see power key got interrupt toggled in /proc/interrupts. Which means pressing power key won’t trigger anything to the system.
We fix that problem in some new Jetpack release.

20

I was using JP6.0 (L4T 36.3).
In fact, so is everything I posted after this one: "...Instead, I chose to install JP6.0 (L4T 36.3)..."

Upon further testing, forcing sudo busybox devmem 0x0c2f1080 to 0x0000004D does not help with the first suspend after reboot.

To remove all misundeartanding, here are my most recent tests on the matter.

Test (basic):

  1. Reboot
  2. cat /proc/interrupts | grep 226 shows 0 interrupts on CPU0
  3. sudo busybox devmem 0x0c2f1080 shows 0x000000ED
  4. Pressed the button, but the system doesn’t suspend.
  5. cat /proc/interrupts | grep 226 shows 2 interrupts on CPU0
  6. sudo busybox devmem 0x0c2f1080 shows 0x000000ED

Test (forcing 0x0000004D):

  1. Reboot
  2. cat /proc/interrupts | grep 226 shows 0 interrupts on CPU0
  3. sudo busybox devmem 0x0c2f1080 shows 0x000000ED
  4. Change value sudo busybox devmem 0x0c2f1080 32 0x0000004D
  5. sudo busybox devmem 0x0c2f1080 shows 0x0000004D
  6. Pressed the button, but the system doesn’t suspend.
  7. cat /proc/interrupts | grep 226 shows 34 interrupts on CPU0
  8. sudo busybox devmem 0x0c2f1080 shows 0x0000004D

Test (software suspend):

  1. Reboot
  2. cat /proc/interrupts | grep 226 shows 0 interrupts on CPU0
  3. sudo busybox devmem 0x0c2f1080 shows 0x000000ED
  4. sudo systemctl suspend and the system suspends.
  5. Pressed the button and the system wakes.
  6. cat /proc/interrupts | grep 226 shows 1 interrupt on CPU1
  7. sudo busybox devmem 0x0c2f1080 shows 0x0000004D
  8. Pressed the button, and the system suspends.
  9. Pressed the button, and the system wakes.
  10. cat /proc/interrupts | grep 226 shows 33 interrupts on CPU0 and 1 interrupt on CPU1
  11. sudo busybox devmem 0x0c2f1080 shows 0x0000004D
  12. Press button, and system suspends.
  13. Press button, and system wakes.
  14. cat /proc/interrupts | grep 226 shows 80 interrupts on CPU0 and 1 interrupt on CPU1
  15. etc.

Test (searching for changed values):

  1. Reboot
  2. Checked addresses 0x0c2f1000, 0x0c2f1020, 0x0c2f1060, 0x0c2f10A0, 0x0c2f10C0, 0x0c2f10E0.
  3. None of those turned out to be of interest.
  4. sudo busybox devmem 0x0c2f1040 shows 0x00000083
  5. sudo busybox devmem 0x0c2f1080 shows 0x000000ED
  6. sudo systemctl suspend and the system suspends.
  7. Pressed the button and the system wakes.
  8. sudo busybox devmem 0x0c2f1040 shows 0x00000003
  9. sudo busybox devmem 0x0c2f1080 shows 0x0000004D
  10. etc.

Test (forcing additional value):

  1. Reboot
  2. sudo busybox devmem 0x0c2f1040 shows 0x00000083
  3. sudo busybox devmem 0x0c2f1080 shows 0x000000ED
  4. Changed value:sudo busybox devmem 0x0c2f1040 32 0x00000003
  5. Changed value: sudo busybox devmem 0x0c2f1080 32 0x0000004D
  6. Pressed the button, but the system doesn’t suspend.
  7. cat /proc/interrupts | grep 226 shows 39 interrupts on CPU0
  8. etc.

Summary of tests:
The command sudo systemctl suspend always works after fresh reboot.
After that, the button will have the desired behavior.
I noticed that an address adjacent to 0x0c2f1080 changed upon successful suspend.
Could there be other addresses that would be relevant here?

I suppose a crude workaround is to have a crontab or one-shot service that runs sudo systemctl suspend upon fresh boot, but I’d rather not have to do that.

Hi,

Some clarification.

  1. Checked addresses 0x0c2f1000, 0x0c2f1020, 0x0c2f1060, 0x0c2f10A0, 0x0c2f10C0, 0x0c2f10E0.

I don’t know what are you trying to do for above. “0x0c2f1080” is the GPIO controller address for GPIO PEE.04 as your power-key. There is no point to check other register because those stand for other GPIOs. Unless you have other GPIO connected and register to be used, otherwise there is no need to check them.

Please test on rel-36.4.3. I don’t think your issue is similar to previous post. Looks like interrupts count are still increasing after modifying value to 0x4D. But somehow suspend didn’t get triggered.
