EDIT/UPDATE: This issue is now resolved
- DO NOT run rpi-update
- DO NOT install the development version
Both of these things may leave your Pi doing unexpected things – they represent the ‘bleeding edge’ of development and they’re just not suitable for the vast majority of users.
It is likely that the issue will be fixed in the next week or two. I will report as soon as I receive word on a proper fix and how to install it.
Pimoroni have issued rather good advice concerning their products and agree with me on the state of things and the need to be patient for the proper fix.
Please bear in mind that this bug will affect everything using RPi.GPIO, including the very-popular Pibrella board and also the CamJam EduKits that we sell through The Pi Hut.
