The BB AI does NOT SUPPORT run-time configuration of the pin-mux (it may allow for changing direction and pull-up/down state for pins currently muxed as GPIO, but does not allow changing the pin mode to some other system). You will have to, at the least, modify /boot/uEnv.txt to load different device tree (overlays) to enable SPI. You may even have to edit and compile device trees to enable some functions. Peruse https://www.element14.com/community/roadTestReviews/3225/l/beaglebone-ai-review (note: this page appears to rely upon making a copy of the original device tree and then copying the roboticscape device tree over the original; I'm pretty certain one could just edit uEnv.txt and replace the device tree file name in that for the same effect) https://www.element14.com/community/community/project14/visionthing/blog/2019/11/16/beagleboard-ai-brick-recovery-procedure -- Dennis L Bieber -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
