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:

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