Hi there! I am developing a software that is to run on a BBB, runing Debian wheezy with 3.14.2x-ti. The sofware is goind to control stepper motors, much like those CNC controllers that I have seen around here, such as machine kit et cetera. So, as I dont have need for hdmi, I am using its pins for my own aplication, since there are a lot of GPIO2 pins in the headers and using a single GPIO allows the better usage of memory access, since more pins can be set in a single memory read-modify-write operation, or even a single write do SETDATAOUT and CLEARDATAOUT registers. I have found a few outdated sources that indicates that I dont need to disable the framer, since it only acts when a display is detected. Some other more recent post point that I can disable it changing uEnv.txt, but on my image, I can't figure how to do this, since the only thing on my uEnv.txt is the kernel string. Can anyone give me a hint on which way is the way? Thanks! Paulo Sherring.
