I am presently using Debian GNU/Linux 7.9 (wheezy) on the BBB. Everything works fine until I reboot the BBB. Before rebooting, I do the following to verify If the SPI0 is enabled.
1. root@beaglebone:/sys/devices/bone_capemgr.9# echo ADAFRUIT-SPI0 > slots *Output* : root@beaglebone:/sys/devices/bone_capemgr.9# cat slots 0: 54:PF--- 1: 55:PF--- 2: 56:PF--- 3: 57:PF--- 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI *8: ff:P-O-L Override Board Name,00A0,Override Manuf,ADAFRUIT-SPI0* The 8th slot is loaded with SPI 0. 1. root@beaglebone:~# ls -al /dev/spidev* *Output* : crw-rw---T 1 root spi 153, 0 Feb 14 05:53 /dev/spidev1.0 Its showing spidev1.0, so its fine 1. root@beaglebone:~# cat /sys/kernel/debug/pinctrl/44e10800.pinmux/pingroups *Output*: group: spi0_pins_s0 pin 84 (44e10950), pin 85 (44e10954), pin 86 (44e10958), Its showing the SPI pins. 1. root@beaglebone:~# sudo nano /boot/uEnv.txt I opened the uEnv.txt file and added this line, so that the SPI0 DT will load during system boot up optargs=capemgr.enable_partno=ADAFRUIT-SPI0 Problem: Why isn't my SPI0 DT being loaded during system boot up?, after a reboot I did steps 1,2 and 3 mentioned above to check, but noticed that the DT fails to load after rebooting. why is this happening? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
