Hello,
This concerns both 1.0 (Limited White Edition) and 1.1 (Crystal Blue Edition).
The USB1T11A (U2) transceiver MUST be removed.
If you are not using dualboot, please put 10kOhm between 3.3V and SWITCH to avoid any problems.
DNU denotes "Do Not Use"
There are no benefits besides dualboot so far.
Notes:
For NOR:
10kOhm pullup resistor on P8
For NAND:
10kOhm pullup resistor on P2
10kOhm pullup resistor on P26
edit: added STP and PDB
