Cape-universal will not load

[maxmike]

I have to revert to bone84 to get these boards out to production and just found a problem with cape-universal.
I'd like to know how to install it at boot time.

uEnv.txt:

#Docs: http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0

uname_r=3.8.13-bone84
#uuid=
#dtb=

cmdline=coherent_pool=1M quiet

##enable Generic eMMC Flasher:
##make sure, these tools are installed: dosfstools rsync
#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh
uuid=1d7c583c-79d0-4a50-9814-5db45bd28f69

I tried modifying the cmdline:
cmdline=coherent_pool=1M quiet cape_universal=enable

I tried loading at runtime :

root@niihau:~# config-pin -q p9.11
cape-universal overlay not found
run "config-pin overlay cape-universal" to load the cape
root@niihau:~# config-pin overlay cape-universal
Loading cape-universal overlay
bash: line 0: echo: write error: File exists
Error loading device tree overlay file: cape-universal

Checked dmesg:

First in /boot/uEnv.txt

enable what you want to disable:

##Disable HDMI/eMMC
#cape_disable=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G

##Disable HDMI
#cape_disable=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN

##Disable HDMI Audio
#cape_disable=capemgr.disable_partno=BB-BONELT-HDMI

##Disable eMMC
#cape_disable=capemgr.disable_partno=BB-BONE-EMMC-2G

Then if you want to enable:

cape_enable=capemgr.enable_partno=cape-universaln
