Systemctl: error starting reform-hw-setup.service

invictvs · May 21, 2024, 6:17am

Hi there,
I just updated my debian installation and I see an error starting the service reform-hw-setup.service.: “Failed to start reform-hw-setup service - MNT Reform Hardware Defaults Setup”.

The issue detected is that “shutdown suspend” never more wakeup. When I push the circle and then wake (space) my laptop does nothing; I have to Power off and then Power on. I dont see any other impact of this issue.

Before the update all was ok.

Output of uname -a is: Linux reform 6.8.9.

Journalctl say that cannot create the wakeup file.

Nothing is pending to be updated/upgraded

Any suggestion?

Thank you

Hi! Which CPU module does your Reform have, and can you paste the output of cat /proc/device-tree/model and the output of sudo systemctl status reform-hw-setup?

invictvs · May 21, 2024, 8:34am

Here you have,

CPU is NXP i.MX8M Quad.
device-tree/model

MNT Reform 2 HDMI

Hi Lukas,
After some digging I did the next change to the reform-hw-setup script:

< echo enabled > /sys/devices/platform/soc@0/30800000.bus/30860000.serial/30860000.serial:0/30860000.serial:0.0/tty/ttymxc0/power/wakeup
< echo enabled > /sys/devices/platform/soc@0/30800000.bus/30890000.serial/30890000.serial:0/30890000.serial:0.0/tty/ttymxc1/power/wakeup
< echo enabled > /sys/devices/platform/soc@0/30800000.bus/30880000.serial/30880000.serial:0/30880000.serial:0.0/tty/ttymxc2/power/wakeup

echo enabled > /sys/devices/platform/soc@0/30800000.bus/30860000.serial/tty/ttymxc0/power/wakeup
echo enabled > /sys/devices/platform/soc@0/30800000.bus/30890000.serial/tty/ttymxc1/power/wakeup
echo enabled > /sys/devices/platform/soc@0/30800000.bus/30880000.serial/tty/ttymxc2/power/wakeup

Now systemctl has no errors and systemctl standby is working as usual

Regards,

Vinicio

You can surround code blocks in triple backticks or indent it by four spaces to not mess up the formatting. This looked better when I read your message in my (text based) email client.

@minute if you can confirm that this is the correct fix, I’ll cook up a patch including a fallback for older kernels and submit a MR.

invictvs · May 22, 2024, 3:16pm

For clarity (apologies) this is are the lines that I modified. Lines 66,67 and 68 in the reform-hw-setup script,

    echo enabled > /sys/devices/platform/soc@0/30800000.bus/30890000.serial/30890000.serial\:0/30890000.serial\:0.0/tty/ttymxc1/power/wakeup
    echo enabled > /sys/devices/platform/soc@0/30800000.bus/30880000.serial/30880000.serial\:0/30880000.serial\:0.0/tty/ttymxc2/power/wakeup

josch · May 23, 2024, 5:17am

Thank you! In the search of a solution that works for new kernels and for old kernels I came up with this invocation of find. Could you please run it and report what its output on your system with kernel 6.8 is?

find /sys/devices/platform/soc/ -wholename '*/tty/ttymxc*/power/wakeup'

invictvs · May 23, 2024, 6:11am

/soc doesnt exist, I changed the path by /soc@0
The execution of
find /sys/devices/platform/soc@0/ -wholename '*/tty/ttymxc*/power/wakeup' gives the output

/sys/devices/platform/soc@0/30800000.bus/30860000.serial/30860000.serial:0/30860000.serial:0.0/tty/ttymxc0/power/wakeup
/sys/devices/platform/soc@0/30800000.bus/30890000.serial/30890000.serial:0/30890000.serial:0.0/tty/ttymxc1/power/wakeup
/sys/devices/platform/soc@0/30800000.bus/30880000.serial/30880000.serial:0/30880000.serial:0.0/tty/ttymxc2/power/wakeup

josch · May 23, 2024, 7:16am

Aha, thank you! Indeed you found a bug in my find command. The fixed version is this and should give the exact same output:

find /sys/devices/platform/soc*/ -wholename '*/tty/ttymxc*/power/wakeup'

If anybody with an imx8mq reform before kernel 6.8 could run this and paste the output, that would be great!

invictvs · May 23, 2024, 7:58am

A final apostrophe (') is missed, I added and executed. The output is the same that I send before

humberto · May 24, 2024, 11:02pm

Output on my i.mx8mq reform2 is:

Thank you all for your help! The problem should be fixed with reform-tools 1.43 in this commit:

mtm · June 6, 2024, 2:35am

Just wanted to let you know that 1.43 fixed the issue for me; my Reform can suspend again. Thanks for all the work.

josch · June 6, 2024, 6:20am

Thank you for reporting it! I cannot fix issues without them getting reported first.

mtm · June 6, 2024, 3:48pm

Ah, wasn’t me but @invictvs that reported it. Regardless, thanks again! Can’t wait for my Pocket and RK3588.
