A follow up to the request by Robert for the uboot power up information from a terminal connection. It finds the cape. Should I be concerned about the
** Unable to read "/boot/uboot.env" from mmc0:1 ** Or is that just because I'm using the SD card to boot? Also I'm playing with the little TFT display: https://learn.adafruit.com/user-space-spi-tft-python-library-ili9341-2-8/wiring My SLOTs BBB OS version has in the uEnv.txt file cape_enable=bone_capemgr.enable_partno=BB-SPIDEV0 while the tutorial above has optargs=capemgr.enable_partno=BB-SPIDEV0 and then says to check /dev/ for the spi ports. "*Reboot your device and you should see the files /dev/spidev1.0 and /dev/spidev1.1 now exist."* This slotless version already has them. debian@ebb:~$ ls /dev/spi* /dev/spidev1.0 /dev/spidev1.1 /dev/spidev2.0 /dev/spidev2.1 Is anything else needed then? The Adafruit Tutorial is then also quite dated and will need to have an addendum or be rewritten. Thanks John Dammeyer Here's the boot up log: [ OK ] Reached target Shutdown.
