Since this is my thread, I though I would reach out to my fellows, both professional (ie. Beagleboard) and hobbyist (that that have ACTUALLY solved this issue and can add something to this discussion) if they can shed some light on the following issues.
I'm serious though about people that have done it before, ok, I've been programming UN*X for quite sometime and already know what a popen and a ps are, we don't need yet another elaboration on it. If you have successfully managed to properly configure the GPIO on a BB I would love to hear from you. And I will proceed with my own research on the subject, posting here. Some of the topics that elaboration would help on are currently: - how conceptually (not technically, functionally, in english) does "overlaying" work. And better if it is a mundain procedure but I do need it explained (would save me some time). - Am I correct in assuming that to commit this "overlay" to OS that I need to "compile" it? Have I got it right that its the DTC compiler at the above URL. - Does this correctly configure my board for the suite of PWM/TIMER/I2C/UART/SPI/CAN/GPIO features available on the p8/9 headers AT START UP? - Down the line: is there a nice tutorial out there or PDF that deliniates a correct procedure for using /dev/ abstraction to access especially the I2C/SPI/UART features via streams (in let's say C). - what is the accepted procedure for accessing the pins in GPIO mode? - A moderators: once we get this issue resolved is there any way we can stickey it to the top of each of the boards sections, as well as the hardware board? I apologize for my forwardness, its just a question. Thank you for your compliance jk. :D On Thursday, March 9, 2017 at 5:17:59 AM UTC-7, woody stanford wrote: > > OK, I want to get to the bottom of this whole GPIO issue on the BBB, so > I'm opening up this thread as a "documenter" whereby which I can take notes > based on my research into how you consistently, stably and SOLIDLY > programatically access the GPIO pins on a BBB.
