Page 6: Getting Started
3.1 Initial setup and pre-programmed demo program The LPCXpresso804 board is pre-programmed with a diagnostic demo program, which tests various features of the board. This program utilizes the UART LPC804 output, which is connected to the debug probe, which acts a serial to USB bridge to a host computer (as well as providing the CMSIS-DAP debug interface.) To ensure a correct operation, a... -

7. Ensuring the LPCXpresso804 is connected to the host computer, click Debug in the Quickstart panel. The IDE will search for available debug probes. Select the debug probe that appears for your board, then click OK. -
Page 8: Debugger Firmware Update (Optional)
An external debug probe that supports ARM’s SWD interface, such as a SEGGER J-Link or PE Micro probe, can be used with the LPCXpresso804 board. The external probe must be connected to header CN1. When an external debug probe is used, the on-board probe must be held in reset by placing a jumper on JP1. -
