Hi,

I have my application running(with LPC1768) that has received the new binary code (to update itself) and placed it at 0x40000.

How update this code to 0x0 address.

Thanks

Hi crp1957,
You will have to use IAP functions. Please looks into page 640 of 849 of LPC175x_6X UM (http://www.nxp.com/documents/user_manual/UM10360.pdf).
Also below application note may be helpful.
