How to Reprogram RL78/G2x Data Flash Memory Using Flash Driver SC Version in IAR EW
May 27, 2026

About This Video

A tutorial for reprogramming RL78/G23 data flash memory using the Flash Driver RL78 Type 01 SC version in IAR Embedded Workbench for RL78. We walk through how to register the Smart Configurator-generated Flash Driver source code in your project, configure build settings, and debug the application. We demonstrate how to perform data flash reprogramming on RL78/G2x devices to support reliable in-system updates.
