So what happens if a cape wants to use the GPIOs that are also HDMI signals? In my case, I am toying with a cape that uses 53 GPIOs.. I had hoped that it's eeprom could indicate that I'm using P8_26 through P8_46 (among others) and I don't intend to have any HDMI going on. Is that not possible?
I mean, if it's the virtual cape manager that makes capes just "work" by reading their eeprom, and you're saying that the Virt Cape mgr needs to be disabled (to also disable HDMI).. then does that mean it's pointless to have an eeprom on my cape?
