I wrote the cape eeprom based on the documentation in the "BeagleBone Black System Reference Manual", Revision A4, January 2, 2013, Table 9 on page 62 and Table 10 on page 64. The cape EEProms in /opt/scripts/device/bone/capes/ don't appear to match the above documentation. Is that documentation wrong?
