X4 gpioinfo/gipiodetect can't find GPIO

#1

The documentation for the X4 mentions that the RP2040 can be reset by pulling one of the x86 GPIOs high for one second

But, after installing gpiod on Ubuntu 24.04, gipiodetect and gpioinfo do not show any information.

Attempts to read the GPIO with gpioget and setting with gpioset just fail.

Did some googling and it sounds like I might not have a GPIO controller driver installed. Is this the case?

Thanks

You need to update a new bios according to this guide.

Thanks, I’ll get it updated. Probably worth mentioning the lowest BIOS version needed in the section of the docs I linked above

#4

The BIOS is placed in the X4/bios directory, the latest update version will be put there as well.

Hi @makerbymistake, BIOS has been updated today, you can try it.

#6

Yep, it’s working with the latest BIOS. Thanks!!

There’s room for improvement naming the GPIO lines so gpioinfo doesn’t just display “unnamed” for all of them
