GPIOs not working anymore after update to TorizonCore 6.1.0

[rubmay07]

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?

Apalis IMX8 GPIO mapping difference between BSP 5 and BSP 6

Hi, We are currently transitioning to the Apalis IMX8 to move away from the Apalis TK1. I’ve been checking out the latest BSP 6 reference images releases for the Apalis iMX8 and found that the GPIO mapping seems to be completely shifted in contrast to BSP 5 and also different to your own documentation (GPIO (Linux) | Toradex Developer Center) On BSP 6, the system the first 2 gpiochips that are usually mapped to the lower GPIO numbers are now mapped to the higher GPIO numbers which messes up th…

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]

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]

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]

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

Best regards,
Martin

[josep.tx]

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

Best regards,
Josep

[josep.tx]

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)
