I see several examples on the web on how to use the Grove-UART port for GPIO. They talk about modifying a line in /boot/uEnv.txt:
For example, this page http://www.seeedstudio.com/recipe/index.php?controller=recipe&action=show&recipe_id=362&ref=product ...states in somewhat broken English: Then blocking “cape_enable=capemgr.enable_partno=BB-UART2” just as the > picture below shows. > #cape_enable=capemgr.enable_partno=BB-UART2 But looking in /boot/uEnv.txt, I'm not seeing this exact line to comment out. I'm running Robert Nelson's Ubuntu 16.04 image. There are hints that a better method exists to do what I want. References like this one from 10 months ago: "Using cape-universal is a better way to enable UART2 these days, rather > than forcing it in uEnv.txt. Most of the Python libraries know how to load > the required cape overlay to enable UART2 and this should be checked." Can someone point me to the right place for me to understand what I need to do? In the end, I want to do is connect a Grove GPIO twig (such as Seeed's chainable RGB LED) to the right-hand-side Grove port.
