OK I'm still somewhat new to using the I/O interfaces on the BeagleboneBlack. I'm currently interested in utilizing the 3.13 Kernel. I realize that there is no capemgr for the newer kernel.
- Is there a capmgr in the works for 3.13 ? - I've taken a brief look at Roberts really simple cape manager https://github.com/RobertCNelson/rscm and it looks very promising. It seems to currently be usable with I2C/SPI/UARTs. Is this something that is being actively worked on. Will there be a sample patches for GPIO (perhaps only one or two example pins) , PWM and ADC added in the future? - Also I've looked at the solution of including device tree overlays in the uEnv.txt file. Is it possible to include more than one .dtbo file in the uEnv.txt file? If so I'd appreciate it if someone can show me an example of the syntax. - If I have a GPIO configured with its receiver enabled (bit 5 set to 1) can the pin still be used as an output (output/input) pin or just an input pin ? In some cases, say when interfacing to a HD44780 LCD you need to have a bidirectional data bus...trying to do this from the user space will be impossible if pinmux can't be accessed from user space. I tried looking at the TRM for the AM335x but couldn't quite zone in on this info. - Finally if I reserve say two GPIO pins for use with a UART in the device tree. Can I still access these pins as gpio via sysfs if the UART is not being used (i.e. open () system call has not been called on (/dev/tty???)). Or is it simply not usable as GPIO whatsoever ? Thanks!
