hello, I tested the HID example on the eval board (with lpc2148) and it works fine. Then I made my own pcb using lpc2146 (not a lpc2148). I can download my firmware using JTAG to the lpc2146. When i start it, then it crashs at startup file. There is any difference between lpc2148 and lpc2146? (axcept flash size) thanks, Joseph
