Some of the pins are mis-labeled.
Pin 9 "GPIO65_ETH1_TRQ1" should be "GPIO65_ETH1_IRQ1"
Pin 65 "EM_NBF0" should be "EM_NBE0"
Pin 69 "EM_NBF1" should be "EM_NBE1"
Pin 30 "GPIO21_MMC3_DAT4" should be "GPIO21_MMC3_DAT7"
Pin 31 "GPIO17_MMC3_D" should be "GPIO17_MMC3_D3"
This page is no longer valid. The 70-pin connectors on each Overo COM are J1 and J4. Pinouts for these connectors are defined here:

The signals defined for J4 are correctly labeled:
