5. Conclusion

1. Overview

• Frequent program downloads are required during development, and the “Online Debug” takes much longer than the “Standalone Download”, which can improve work efficiency.
• Keil, IAR, STM32CubeIDE, and RT-Thread Studio all come with both “Online Debug” and “Standalone Download” buttons.
• How to let e2studio add a standalone download button —> Call J-Link from external tools.

2. References

• Refer to the “Standalone Download” feature of RT-Thread Studio to implement adding a “Standalone Download” button in e2studio.

Working Directory:

${project_loc}

Arguments:

-device R7FA6M4AF -ExitOnError -CommanderScript download_init.jlink

4.2 Add .jlink Script

download_init.jlink should be placed in the root directory of the project.

5. Conclusion

• By calling jlink.exe from external tools in e2studio (Eclipse), the download is performed via jlink commands.
• e2studio does not display related tools by default; you need to show the toolbar and set shortcut keys.
