I haven’t been following the postings to closely related to the BBG and have run into a small problem.
I’ve built a new 4.1 system using Robert C Nelson’s instructions from the eewiki.
Root file system:
wget -c https:``//rcn-ee.com/rootfs/eewiki/minfs/debian-8.2-minimal-armhf-2015-09-07.tar.xz
Current /boot/uEnv.txt contents:
uname_r=4.1.12-bone16
dtb=am335x-bonegreen.dtb
cape_enable=bone_capemgr.enable_partno=BB-UART2
uuid=d8dfc06b-1696-4918-9a58-9c781183bbea
I used the flasher script:
bbb-eMMC-flasher-eewiki-ext4.sh
To copy the working uSD card to the eMMC
I followed the capemgr instructions for v4.1.x+ on the BBG after booting, no problems encountered there.
All is working except I’m getting capemgr load failures.
Partial dmesg output:
