I am using Ubuntu 15.04 and the BB Debian image on my BBB is 2014-04-23. I have been trying for some days now to disable my HDMI and HDMIN overlays so that I can access my BB-SPIDEV1 with limited success. One command in particular (i.e. optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN) does indeed disable HDMI yet with that said it will not allow me to enable SPIDEV1. I have boldface highlighted the commands that were used as well as the o/p for presentation purposes. Any insight into resolving this problem would be helpful and much appreciated. Further note: I also tried optargs=capemgr.disable_partno=BB-BONELT-HDMI and all to no avail. *uEnv.txt* ##Disable HDMI #optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN #cape_disable=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN #optargs=capemgr.disable_partno=BB-BONELT-HDMI *optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN* *optargs=capemgr.enable_partno=BB-SPIDEV1* #optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN dean@beaglebone:~$ 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* *6: ff:P-O-L Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN* *7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-SPIDEV1* -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
