I have some problems with peripherals when using Debian 8 or Ubuntu 16 - both have kernels with bigger version than 4. For example my UARTs don’t get any data when checking via minicom. I had no problems with older version of the kernel (ver 3.8). This situation is present on nearly clear installation (some apt-get updates, upgrades only). Any ideas?
The same question goes to acces to peripherals when using Python. For kernel 3.8 there is awesome Adafruit_BBIO but there is question what about linux kernel 4 where some things are totally different?
Thank you for your help!
