If R14 has printed "100" on it, that means 10 ohms, 100 ohms would be "101" or "1000".

Anyway, I don't know if this would help in this case, may be that some CIII Starter Boards have general problems with external JTAG connection. JTAG confifuration has always priority, there are only a few pins that could disturb JTAG programming, nCE is among them, but it has only a connection to GND through a pulldown resistor with the Starter Board. Of cause J8 must be placed to disable onboard JTAG. Users reported, that USB power would be needed in addition, but I don't see why.
