Why am I not receiving a 60 MHz signal from CLKOUT in sync.FIFO mode on the FT2232H?
I know that https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT2232H.pdf give the impression that one either needs an EEPROM for sync FIFO or can configurate it via software. But https://www.ftdichip.com/Support/Documents/TechnicalNotes/TN_167_FIFO_Basics.pdf states that both are actually required and that the right setting has to be set e.g. vias FT_PROG. Please check if this is the case.
