Hello all, To get the 48 MHz necessary for the LPC214x USB, you must use a crystal of 12.0 MHz, 16.0 MHz, or 24.0 MHz. None of these frequencies are mentioned in the manual table 291 that lists the possible ISP baud rates with various crystal frequencies. Can you use serial ISP with 12/16/24 MHz, and with which baud rates? Karl Olsen
