The /dev/gpiochip* entries are not seen on my upsquared 6000. Running the 5.4 kernel downloaded as described in the wiki

Hi @rvup,

Can you share more details about your test setup and what error you get?

rvup

Hi @camillus,

I have a new upsquare 6000 booted up on 5.4 and with libmraa installed as per wiki.
My error is identical to what @saket posted above.

Hi @rvup

You are following the standard setup for the UP Series, which is not the right one for our new products.

Please check out this link and install Ubuntu from the installer highlighted here: https://github.com/up-board/up-community/wiki/Ubuntu#ubuntu-for-up-xtreme-i11-and-up-squared-6000

If you need MRAA, then, the version included in Ubuntu 20.04 does not support our new products.

Please add our PPA and install MRAA as described here: https://github.com/up-board/up-community/wiki/MRAA#setup-for-up-xtreme-i11-and-up-squared-6000-on-ubuntu-2004

We are currently looking into some missing packages in our PPA (UPM libraries and few others) that will be added soon to our repository

Thanks for your reply @DCleri.
I have ubuntu from your github. Also libmraa from the PPA.

'mraa-gpio version' shows Version v2.1.0 on UP2_6000

Have you update the repo now and provided the missing packages?

@Dcleri : on your upsquare 6000, can you see /dev/gpiochip* ?
