I have recently took my Beagleboard-xM (Rev B) and put on it the Ubuntu 14.04 LTS (3.14.2-armv7-x5), then I tried to mux Pin3 (GPIO_139), after reading thoroughly the pages from both the "System Reference Manual"(Page 110) and the "Technical Reference Manual" of the processor (Pages 2444-2453). So I wrote the dts file and compiled it via dtc.
but now I got stuck . how do I apply the changes on runtime?
I saw on the beaglebone there is a slots file (/sys/devices/.../slots) which was triggering the change, after we echoed to it the dtbo file. but in my case we are talking about beagleboard-xM which there is no such kind of file. can someone elaborate what should I do?
Any suggestion would be great! thank you all.
