OK, thanks. Followed your instructions for wget. It's amazing to me that BBB can do this sort of major update "in place" with only 4 GB of flash.
Then I edited /boot/uEnv.txt so now the first lines of that are: *#Docs: http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0 <http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0>* *uname_r=4.1.2-gitf4ce60f0b74d04db24b7b0fd8fb574ead7ceb16c* *## HDMI disabled but emmc enabled, I think/hope* *dtb=am335x-boneblack-emmc-overlay.dtb* *##BeagleBone Black dtb's for v4.1.x (BeagleBone White just works..)* *##HDMI/eMMC disabled:* *#dtb=am335x-boneblack-overlay.dtb* *##cape-universal* *#dtb=am335x-boneblack-universal.dtb* *Do I also need the dtb for this cape-universal? Is that a specific cape or something used by all capes?* Then reboot. It still boots from eMMC with the new uEnv.txt. *ubuntu@arm:~$ uname -a* *Linux arm 4.1.2-gitf4ce60f0b74d04db24b7b0fd8fb574ead7ceb16c #108 SMP PREEMPT Thu Jul 16 19:06:39 UTC 2015 armv7l armv7l armv7l GNU/Linux* so it has the new kernel. Time to plug into LCD7 and see what happens. First shutdown cleanly. *When I hold the power button for several seconds, then release, no shutdown initiates. ???* so instead sudo shutdown now hmm.. there seem to be new options in the serial monitor... which seems to prevent shutdown. When I try to enter the "temppwd" the system just boots up again, same as Control-D *The system is going down for maintenance NOW!* *ubuntu@arm:~$ wait-for-state stop/waiting* * * * * * Stopping rsync daemon rsync [ OK ] * * * Stopping DNS forwarder and DHCP server dnsmasq [ OK ] * * [ OK ]* * * Killing all remaining processes... [fail] * * * Will now switch to single-user mode* *Give root password for maintenance* *(or type Control-D to continue): * *rc-sysinit start/running, process 2809* * * Loading cpufreq kernel modules... [ OK ] * * * Starting DNS forwarder and DHCP server dnsmasq [ OK ] * * * CPUFreq Utilities: Setting ondemand CPUFreq governor... [ OK ] * CPU0... * * * Starting web server apache2 * * *Ubuntu 14.04.2 LTS arm ttyO0* So I don't know how to do a clean shutdown... Anyway on to try LCD3 Rev A.

Something else I should configure?
