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. It was found in /boot/ But when I did this, ie reboot and look, it seems that the HDMI is still there: root@beaglebone:/var/lib/cloud9# cat /sys/devices/bone_capemgr.*/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 root@beaglebone:/var/lib/cloud9# ==== I have now tried the advice of Vinay: Another solution is also simple, just include the line "CAPE=ADAFRUIT-SP0" in /etc/default/capemgr file. Then reboot and all should work fine. ======== This did not work. I still get the same slots listing. I then followed this advice also from vinay: ============ Re: [beagleboard] Re: Issues with Enabling SPIDev on Beaglebone Black Other recipients: [email protected], [email protected] Step 1 : Go to root@beaglebone: /boot# Step 2 : Open uEnv.txt file Step 3 : Inside the file You will find these lines, so do the following: In case If you dont find these lines for your kernel, then just append the line "cape_enable=bone_capemgr.enable_partno=BB-SPIDEV0" to the end of the file. ##Example v4.1.x #cape_disable=bone_capemgr.disable_partno= cape_enable=bone_capemgr.enable_partno=BB-SPIDEV0 Step 4 : Reboot your BBB Step 5 : Go to /sys/devices/platform/bone_capemgr# cat slots or dmesg to check. Then check if your SPI device has been loaded. This works with Linux beaglebone kernel 4.1.18-ti-r53 =============== This didn't work. there is no /sys/devices/platform/bone_capemgr. I would be very grateful for any help with this.
