Hi all, my SPI0 is configured and it works (the device which is connected to SPI0 functions properly) Unfortunately, I do not understand how it is configured and I cannot ask the author.
Can you please give me a hint where I can find the configuration ? root@beaglebone:~# uname -a Linux beaglebone 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015 armv7l GNU/Linux 1) The overlay looks good: root@beaglebone:~# cat /sys/devices/bone_capemgr.9/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 7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-SPIDEV0 2) dmesg does not not say why BB-SPIDEV0 is loaded: [ 177.147378] bone-capemgr bone_capemgr.9: part_number 'BB-SPIDEV0', version 'N/A' [ 177.150423] bone-capemgr bone_capemgr.9: slot #7: generic override [ 177.150483] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 7 [ 177.150533] bone-capemgr bone_capemgr.9: slot #7: 'Override Board Name,00A0,Override Manuf,BB-SPIDEV0' [ 177.150781] bone-capemgr bone_capemgr.9: slot #7: Requesting part number/version based 'BB-SPIDEV0-00A0.dtbo [ 177.150828] bone-capemgr bone_capemgr.9: slot #7: Requesting firmware 'BB-SPIDEV0-00A0.dtbo' for board-name 'Override Board Name', version '00A0' [ 177.150898] bone-capemgr bone_capemgr.9: slot #7: dtbo 'BB-SPIDEV0-00A0.dtbo' loaded; converting to live tree [ 177.154033] bone-capemgr bone_capemgr.9: slot #7: #2 overlays 3) /boot/uEnv.txt does NOT have any changes (everything is commented out) 4) /etc/default/capemgr does not contain SPI: # Default settings for capemgr.
