Hi I have a LPC2138 soldered onto my own board. I have a USB-serial bridge IC attached to UART0. I am using a 12MHz crystal (I have also tryed 16MHz) I have no 32kHz crystal attached. Using Phillips flash utility I can read device ID: 196389, Boot loader ID: 2.0. I can successfully erase and blank check. However when I attempt to Upload Flash it fails mid way through the write. I have tryed using all the baud rates. Any ideas?
