Whats crack'n Vinay!! Looks to me like Wheezy. Hey Will, 5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI 6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN The L in P-O-L means loaded, so in the case above it's telling you that the HDMI hasn't been loaded. So you've successfully disabled it.
When you do this "Another solution is also simple, just include the line "CAPE=ADAFRUIT-SP0" in /etc/default/capemgr file. Then reboot and all should work fine" You'll have to do both, disable the HDMI like you've done (if you want to use SPI1) and load the SPI dtbo like in the step above. You should then see it loaded when you cat the slots. Below is what mine looks like (I have a few different things loaded, but you can see that the HDMI has been disabled and both SPI's loaded) root@beaglebone:/sys/devices# cd /sys/devices/bone_capemgr.* 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-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI 6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN 7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-SPI0-01 8: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-SPI1-01 9: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART1 10: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART4 11: ff:P-O-L Override Board Name,00A0,Override Manuf,AEI-UART5 12: ff:P-O-L Override Board Name,00A0,Override Manuf,bspm_P8_32_f 13: ff:P-O-L Override Board Name,00A0,Override Manuf,am33xx_pwm 14: ff:P-O-L Override Board Name,00A0,Override Manuf,bone_pwm_P9_16 root@beaglebone:/sys/devices/bone_capemgr.9# check for 'spidev1.x' in /dev e.g root@beaglebone:~# cd /dev root@beaglebone:/dev# ls If spidev is in there, you successfully loaded the SPI This is the version of linux I'm running on my BBB root@beaglebone:~# uname -a Linux beaglebone 3.8.13-bone79 #1 SMP Tue Oct 13 20:44:55 UTC 2015 armv7l GNU/Linux On Tue, Jul 19, 2016 at 11:11 AM, Vinay Divakar <[email protected]> wrote: > Can you provide info about the kernel your using? > > On 18 July 2016 at 13:02, <[email protected]> wrote: > >> Hello all, I am new to BBB and using it to flash the ROM on my Lenovo >> Thinkpad T400 with Libreboot, using these >> <http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0> instructions on >> eLinux. >> >> I disabled HDMI on the Beaglebone by opening vi and removing the comment >> from the line that says it disables HDMI. >> >> I couldn't locate the uEnv.txt file at first, because there isn't a /lib/ >> directory.
