I am a dumb software guy just about to start smoke testing PMODs with my microZed & IOCC.
I have been noting various errata for different hardware versions.
The "usual" silk screen location for the version seems to be "unfilled":
MBCC-IO-[blank rectangle]
Z7MB-7X0x0-ASY-[blank rectangle]
On the IOCC I note that there's actual copper with "MBCC-IO-PCB-D" next to the PS-PMOD connector, on the microZed, underneath near the PMOD connecter is "Z7MB-7Z0x0-PCB-F"
Are these the IOCC and microZed revisions the errata refer to (eg: there's that USB resistor errata, will you respin the PCB for that?)
