Hello, I have a Nexys A7 and work for the Mega65 project where I need to check timing of the UART protocol with my oscilloscope. Unfortunately, the schematics of the Nexys are omitting the USB/UART part ("intentionally left blank"), thus I had to inspect the Board: Tracing the Ch B lines of FT2232H I see there is another IC in-between, which I failed to identify. Marking is hard to read, but looks like ON LC126, but I don't see a datasheet for it. Can you advise me where I can best probe RX/TX signals coming from FPGA and also tell me which IC is in-between FPGA and FT2232H ? Thanks & Best, B. Toschi
