描述
Flash memory reprogramming software for RL78/L23 has been released.
The code flash library is free-of-charge software that reprograms the contents of the code flash memory by user programs.
"Renesas Flash Driver for RL78" is free-of-charge software that reprograms the contents of code flash memory and data flash memory by user programs.
特性
- Flash Self Programming Libraries provide the interface for operations on the code areas of flash memories that MCUs have. (Functions are supported varies with the MCU. Please check the available functions in the user's manual for the target flash reprogramming software.) ：
- Erasing
- Programming
- Internal verification
- Blank checking
- Security settings, etc.
- An EEPROM emulation library for code flash memory is also included.

This video demonstrates how to reprogram the RL78/G2x extra area using the Renesas Flash Driver RL78 Type 01 Smart Configurator version. It covers how to obtain and register the necessary components through Smart Configurator in e² studio, as well as the project setup and debugging steps to reprogram the Flash Shield Window (FSW) control information in the extra area on the RL78/G2x.

- In the User's Manual (Hardware) for some RL78 MCUs or the User's Manual for some Flash Libraries for the RL78 family, the self RAM areas used in common for all flash libraries may be shown. However, for the latest information, please refer to the RL78 Family Self RAM list of Flash Self Programming Library Rev.3.05 (PDF | English, 日本語).
- As the self RAM areas are used as the work area for the library, using these areas for the user program is prohibited. For the latest information, please refer to the RL78 Family Self RAM list of Flash Self Programming Library Rev.3.05 (PDF | English, 日本語).
