Ubuntu 22.04 mraa
I'm having issues trying to get GPIO functionality on Ubuntu 22.04 working. I installed the pinctrl package and built & installed mraa from source, but running
mraa-gpio list gives me "no pins". The mraa examples also seem to error out not being able to find pins. Any solutions?
In the past, I believe the correct way to do this was to use the UP fork of mraa. However, I just tried this with
sudo add-apt-repository ppa:up-division/mraaand was notified that there is no Jammy release file for it. Which makes it sound like Ubuntu 22.04 isn't being supported?
I tried building the up version of mraa for 22.04 and still can't detect pins. Is there an alternative to using mraa on 22.04 for pin/spi control?
install UP HAT pinctrl-upboard driver
build and install mraa from up-rpi branch
GPIO mapping is the same in all upboards with new pinctrl-upboard driver, you can refer our wiki for GPIO number
That worked, thanks! There is one more issue though. The board will now hang on shutdown/reboot after installing the up-extra package to enable user-space GPIO access.
could you take a screenshot to see if there any information to know hang in where?
