Can't set pin USB_H_DATA on i.MX6 SoloX

Hello everyone,

we are trying to set pin USB_H_DATA (GPIO7 IO 10) but are unable to do so.

We tried it with 'gpioset /dev/gpiochip6 10=1' but reading back the pin always gives zero.

Also, the pin stays at 0 V.

Additionally, we tried it both via device-tree and from within u-boot.

Other GPIOs on the same bank seem to work, except for USB_H_STROBE.

Do you have a suggestion on what is going wrong here?

Thank you very much,

Maik

Hi Maik

this may be hardware error, connections with other signals, one can

check board layout and perform x-ray screening. May be useful to attach jtag

and toggle gpio, run bare metal test below:

rt-thread/bsp/imx6sx/iMX6_Platform_SDK/sdk/drivers/gpio at master · RT-Thread/rt-thread · GitHub 

Regarding "USB_H_DATA (GPIO7 IO 10)" one can recheck:
