"cape_enable" is a variable that places the following text into the Linux
boot time parameters.

If you ...

debian@beaglebone:~$ *cat /proc/cmdline*
console=tty0 console=ttyO0,115200n8
beaglebone-capemgr.enable_partno=BB-CAN1 root=/dev/mmcblk0p1
rootfstype=ext4 rootwait fixrtc

You most likely will see that your uEnv.txt modification did not "stick.
