Modifying Debug Firmware on i.MX RT10xx Boards

This application note from NXP Semiconductors provides detailed instructions for modifying the debug firmware on i.MX RT10xx evaluation boards. These boards feature an LPC4322 MCU-based debug probe, offering flexibility in debugging capabilities.

Users can choose from three primary firmware options for the debug probe:

• OpenSDA DapLink: The factory default, offering drag-and-drop programming.
• LPC-Link2 CMSIS-DAP: Provides higher performance flash programming.
• SEGGER J-Link: An evaluation version offering enhanced features.

The document outlines the process of flashing these alternative firmwares (LPC-Link2 CMSIS-DAP and SEGGER J-Link) onto the debug probe using the LPCScrypt utility. It also details how to revert to the original OpenSDA DapLink firmware.

This guide is essential for developers working with NXP's i.MX RT10xx series who need to customize their debugging environment for optimal performance and functionality.
