Okay, out of the box, that image shipped with 3.14.x, so you need to downgrade to 3.8.x to use "capemgr.enable_partno=BB-UART2" cd /opt/scripts/tools/ git pull sudo ./update_kernel.sh --stable --bone-channel > I think I should add this line /boot/uboot/uEnv.txt in the eMMC, am I right?

If you look at /uEnv.txt closely, it reads /boot/uEnv.txt...
