The LPC1788 is on custom board? You should double check you're actually booting the part into the ISP.
After flashing, LPCXpresso attempts to reset your processor and run to the first breakpoint. An access at 0xE000EDF0 would suggest a wire error occurred during/after reset, and LPCXpresso failed to reestablish debug control. Chances are, the image was successfully flashed. To check if this is the case, in your Debug Configuration, set "Load image" to 'false', and start a debug session. If the reset problem persists, you should get a different error.
