Most of this work was developed on a SAMA5D4-MB Rev C. board. Here is a
pin-for-pin comparison between the Rev C and Rev E boards. This is a
comparison of signal naming only; some differences are simply due to
differences in naming and any functional differences with no signal name
change would no be noted.
