trouble with mapping P8.40

[jonturner53]

Have been using config-pin for sometime with no problem, but for
some reason am having trouble with P8.40. When I type

config-pin P8.40 in-

I get

P8_40 pinmux file not found!
cape-universala overlay not found
run "config-pin overlay cape-universala" to load the cape

When I type cat /sys/devices/platform/bone_capemgr/slots, I get

0: PF---- -1
1: PF---- -1
2: PF---- -1
3: PF---- -1
4: P-O-L- 0 Override Board Name,00A0,Override Manuf,cape-universaln
5: P-O-L- 1 Override Board Name,00A0,Override Manuf,BB-ADC

If I run config-pin overlay cape-universala, I get

config-pin overlay cape-universala
Loading cape-universala overlay
bash: line 0: echo: write error: File exists
Error loading device tree overlay file: cape-universala

Please let me know what I am doing wrong.

Thanks,

Jon Turner
