Review: BlueBoard-LPC1768

in dev boards by Arup | 13 comments

Jeffrey wrote a review of the NGX technologies BlueBoard LPC1768 Cortex-M3 development board. It comes with a unique USB bootloader that appears as a USB flash drive. Just drag a firmware update into the drive.

The greatest advantage of this board is that it can be flashed using its USB port. There is no seperate flashing tool hardware or software needed. Just plug the board into the USB port and press a button sequence. The board will appear as an mass storage device(like our USB pen drives). The compiled bin just has to be pasted into the drive. Once the reset button is pressed, the new compiled software will start to work.

    1500 Ruples to USD is 30 dollars. Not bad at all.

    BTW, NGX was the first(?) out with a NXP Cortex-M4 dev board. It’s kind of (is?) the M4 LPCxpresso board for NXP, at least so far.

    I don’t have time to dig through this product’s files. Is the drag and drop bootloader open-source? If so, what’s the license.

      If you are too lazy to Google it, just email the company, they will know.

      NXP chips have a bootloader in ROM.

      • makomk says:

        I’m pretty sure the ROM bootloader on this chip only supports serial, so you need a secondary bootloader in order to do something like this.

      • magetoo says:

        You are right makomk, I was thinking about the 13xx parts, it seems that the 17xx ones do not have a USB bootloader in ROM.

    I believe there is NXP sample code to do it as well, might be what they have based it off. It’s built in to some of the LPC’s as well. LPC11U has a built in USB stack in ROM, it has a boot pin that activates a Mass storage device that lets you drop a hex file into it for flashing.

    Hello

    The drag and drop bootloader is indeed open source.
    When you install LPCXpresso it installs a lot of examples for all LPC1XXX microcontrollers and I found a USB bootloader example that leaves 448Kbyte of user space.
    Haven’t tested it so it could be that NGX edited it a bit.

    The NXP LP17xx series are FS (Full Speed, 12Mbit/s) only.
    For HS (High Speed, 480Mbit/s) you need AT LEAST the LP18xx series.

    That’s the (2500R) LC1830-Explorer: http://shop.ngxtechnologies.com/product_info.php?cPath=21_33&products_id=105
