I'm connecting some external modules that require 1.8V I/O via the SMC bus and some GPIO to a bf707 ez-board.
Have anyone patched the ez-boards vdd_ext to 1.8V before?
From the schematic the patch it looks pretty straightforward by removing R106 and P10, and instead connect P12 to P10.
I suspect that there could be some issues with the on-board chips, like the soft switches for example.
No on-board functions are needed except the cpu and jtag interface.
PB_00 - PB_15 and PA_00, PA_01, PA_02, PA_08, PA_13 and PA_14 are routed to the peripheral.
I don't mind removing a few components if needed.
