Anand! They did it again! The image has all the older items I was used to using! Anyway, it works. I had a very old image on my AI which was obsolete...
- git clone https://github.com/beagleboard/BeagleBoard-DeviceTrees - cd BeagleBoard-DeviceTrees && make - git clone https://github.com/derekmolloy/exploringBB - cd exploringBB/chp08/spi/spidev_test/ && nano (or your favorite editor) spidev_test.c - On line 32, change '/dev/spidev0.1' to '/dev/spidev1.1' - Then... - On your overlay that was made w/ make, C & P it in /boot/uEnv.txt - The file is in BeagleBoard-DeviceTrees/src/arm/overlays/ - It is called BBAI-SPI0_1.dtbo - That should do it but first, reboot the board w/ sudo shutdown -r now! That is what I was attempting in my gibberish earlier in my 2000 posts I made but all along, I have this outdated image and was thinking I could do it w/ the current config.
