So have you checked power? In particular note that you need to provide power to the baseboard directly, not just rely on the power from the USB debug connection to the LPCXpresso1769 board. For more details, check the documentation for the baseboard available from the Embedded Artists website.

You might also need to recover your board, depending upon what code you just programmed into it : http://www.lpcware.com/content/faq/lpcxpresso/regaining-debug-access

Also check through the other relelated FAQs, including those at:

Thanks mate, it is not a power problem
1. setup ISP boot mode
2. Press and hold SW3
3. Press and released Reset
4. Release SW3

try , if it it is not working then check the soldering and connection of SW3 and the best way
1. solder the wire on LPCexpress board P2.10(ISP) pin
2. Solder wire to VCC
3, Solder wire to Gnd

repeate the above procedure using ISP, VCC and gnd
