Arduino IDE 2.x: GD32 boards do not appear in Boards Manager

[Saandeeparduino]

Environment
Arduino IDE: 2.3.2
OS: Windows 10 64-bit

Board Manager URL:

https://raw.githubusercontent.com/CommunityGD32Cores/GD32Core-New/main/package_gd32_index.json

Description

I added the official GD32 Boards Manager URL in Arduino IDE and restarted the IDE. The package index downloads successfully, and package_gd32_index.json is created in the Arduino15 directory.

However, no GD32 boards appear in the Boards Manager when searching for GD32, GigaDevice, or GD32Community.

What I checked
The JSON URL is accessible.
package_gd32_index.json is downloaded successfully.
Arduino IDE version is 2.3.2.
Restarted Arduino IDE multiple times.
Cleared the package cache and tried again.
Additional observations

The current package_gd32_index.json references platform version 0.0.1. It appears the package may be incomplete or incompatible with Arduino IDE 2.x.

There is also a related issue (#135) reporting installation failure due to a missing platform archive checksum. It is possible this issue is related to the package index or metadata.

Expected behavior

The GigaDevice GD32 platform should appear in Boards Manager and be installable.

Actual behavior

No GD32 platform is displayed in Boards Manager, so installation cannot be started.

Could the maintainers please verify whether the current package_gd32_index.json is compatible with Arduino IDE 2.x and whether any required metadata is missing?

Problem Solved 🎉

The issue has been resolved. The current package works with Arduino IDE 1.8.19.

However, it would be great if the project could be updated to provide full support for Arduino IDE 2.x, as it is now the recommended IDE and is widely used by students and educators.

@maxgerhardt, I understand that updating and maintaining this project requires a lot of time and effort. I truly appreciate the hard work you and the other contributors have put into making the GD32 Arduino core available.

I believe that improving Arduino IDE 2.x compatibility and making the installation process smoother will help the GD32 MCU become much more popular within the Arduino community. We know the capabilities of these MCUs—they are excellent devices with great value.

From an educational perspective, we are planning to use GD32 MCUs in our university's undergraduate (UG) embedded systems laboratory curriculum. Having an easy installation process and a beginner-friendly experience would make it much easier for students to start learning without facing setup issues.

If there is anything the community can do to help with testing, documentation, or feedback, we would be happy to contribute.

Thank you again for your dedication and for supporting the open-source community.
