Let me start with saying I am a complete newb, don't work with linux every day.
I have a BBB, revision C. It is freshly flashed with bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.img.xz and has been updated to Debian version is 8.9 Kernel version is 4.4.54-ti-r93. It has the Adafruit_BBIO installed. After struggling to get some UARTs working, I found some online threads which stated: https://stackoverflow.com/questions/35881761/enabling-uart-on-beaglebone-black > > Apparently the powers that be like to change files to keep us on our toes. > > TamusJRoyce left a comment here: > http://www.thing-printer.com/cape-manager-is-back-baby/ that helped me: > > /media/BEAGLEBONE/env.txt and /boot/uBoot/uEnv.txt has moved to > /etc/default/capemgr (file which may not exist). It also has a new syntax. > Add "CAPE=BB-SPI-01,BB-UART1,BB-UART2,BB-UART4" to get main ports working. > Then reboot. > I added CAPE=BB-UART1,BB-UART2,BB-UART4 and that finally got the UARTS working. I was able to open them from python, stream serial data from one to another, and get serial data to-from a separate microcontroller. Now I am trying to get some simple GPIO pins working from Python. The Adafruit example doesn't seem to work (or perhaps it no longer applies with newer debian BBB). At any rate, can someone tell me what to do to get P9.23 (GPIO_49) working? Do I have to add some more entries in the file "/etc/default/capemgr" ?
