Hi Martí, I ran some tests here and found that removing the EEPROM indeed caused the ADCPro Plugin to not connect. The interesting thing was the two EVMs I tested had blank EEPROMs. We think that the ADCPro software is simply looking for an ACK from the I2C EEPROM, therefore, a blank EEPROM would seem to be a requirement on any testboard that intendes to utilize the MMB0 and ADCPro . For compatibility, I would also recommend keeping the U7 GPIO expander on your testboard. I'm not sure why this was implemented in this way, but this seems to be a quirk with this particular EVM that was later fixed with other ADCPro-based EVMs. I think the idea of reusing the EVM motherboard and software to test out the analog performance on a custom prototype board is a great idea, and it is something I will keep in mind when working on future EVMs!
