  • I've been working for a month on a board. Hardware is nice and reliable, the board includes almost everything you need to harness the power of LPC4300 system. One this missing is ethernet phy IC.

     

    Be careful of DNP (do not populate, ie missing) components in shematics. There is no second U15 flash chip. Audio input is wired for microphone, not for line in (resistors R29 to R32 need to be reconfigured for line in to function properly).

     

    You can use DFU to upload software via USB (without debugger), but once you write valid image to internal flash, you can no longer use DFU. I added jumper to my board to be able to pull-up P2_7, which enables DFU on reset even with valid image.

     

    The documentation is horrible, best throw it all away and double-check everything yourself. Boot switches are upside-down and reversed, so that table in user manual is just plain wrong. Sample code included on this site is of lowest quality I've ever seen in published software, and parts of it are not even for this board but for Hitex dev kit! Element14 should just remove this code base, it does nothing but waste our precious time.

     

    In my opinion, the best thing to do is to download newest LPCOpen lib and port the HAL layer (board.c and board_sysinit.c) to this board. I've been able to get it up and running on linux with free tools (arm gcc toolchain, openocd, buspirate as jtag adapter, gdb).
