GPIOs not working anymore after update to TorizonCore 6.1.0

rubmay07 · April 14, 2023, 5:08am

We are currently working with verdin imx8m-mini on a custom board and use some GPIOs that worked perfectly fine. We updated TorizonCore from 5.1.0+git.afc2df4893e6 to 6.1.0+git.349786b46e61 and since then some of the GPIOs are not controlable anymore and are set HIGH all the time.
These GPIOS are:

/dev/gpiochip2, line 10
/dev/gpiochip2, line 11
/dev/gpiochip2, line 12
/dev/gpiochip2, line 13
/dev/gpiochip4, line 26

The GPIOs are neighter controlable via the command line interface nor our control software (python) which was (successfully) used on TorizonCore before the update.

According to the output of gpioinfo the pins should be useable:

Can anyone help me to get the GPIOs working again?

Hello @rubmay07 ,

Your issue might be related to this thread. Can you have a look at it?

Best regards,
Josep

Hello @josep.tx,
thank you for your quick reply. I checked your linked answer but unfortunately it didn’t help.
If I use gpiofind i.e., gpioset $(gpiofind "SODIMM_168")=0 nothing happens, the pin stays in high state as it is since boot time.

jeremias.tx · April 14, 2023, 7:50pm

Were you using a custom device tree or overlay for these pins in TorizonCore 5? The device tree used in TorizonCore 5 does not have SODIMM 168 configured as a GPIO, so I’m curious how you were able to use this as a GPIO before.

Best Regards,
Jeremias

rubmay07 · April 14, 2023, 8:21pm

No, we use no special device tree or overlay, just TorizonCore installed via EasyInstaller. All used GPIOs work flawlessly on TorizonCore5 but stopped working now with Version 6.

Hello @rubmay07
Would it be possible for you to send us the schematics of your custom carrier board ( or at least the GPIO section) to support@toradex.com mentioning this topic? That would help us to better understand your problem.

Best regards,
Josep

Hello @rubmay07 ,
Were you able to sole your issue? Do you need more help on our side?

Best regards,
Josep

rubmay07 · May 10, 2023, 2:56pm

Dear @josep.tx,
I just sent you the board design via email as requested.

Best regards,
Martin

josep.tx · May 11, 2023, 7:56am

Hello @rubmay07 ,
Thanks, we confirm that we have received it.

Best regards,
Josep

josep.tx · May 24, 2023, 9:58am

Hello @rubmay07 ,
Unfortunately we are not able to reproduce your issue.
Could you please send us the boot log of the module and the gpioinfo output for both TorizonCore versions that you are using?
5.1.0+git.afc2df4893e6
6.1.0+git.349786b46e61

Best regards,
Josep

Hello @josep.tx,
here is the output of gpioinfo:

already using the next version of TorizonCore: 6.2.0+git.aa0ff7e3554e (but same problem)

How do I retrieve the bootlog?
Thank you for your help &
best regards,

Hello @rubmay07 ,
Thanks for the provided info

Yo have to connect to the module via serial console and reboot it. The output that you get is the boot log.

Best regards,
Josep

Hello @rubmay07

Do you have any updates on this topic? Were you able to get the boot log?

Best regards,
Josep

Hi @josep.tx,
I’m working on getting the boot log. Due to our custom carrier board, where UART0 is in use for RS485 some soldering is required to get the original boot log out. I am in contact with our hardware department an let you know as soon as I have more information.
Best regards,
Martin

Hello @rubmay07 ,
Do you have any updates?
Also, have you tried with a more recent version? (6.2)

Best regards,
Josep
