Technical issues can be reported through multiple channels. For general questions, contact our FAE team via email or phone. For specific issues, provide detailed information including processor model, board revision, software version, and problem description. Include logs, error messages, and steps to reproduce. For hardware issues, provide schematics and scope captures if applicable. Our FAE team will acknowledge receipt within 24 hours and provide initial response within 2 business days. Complex issues may be escalated to Loongson engineering. Issue tracking is available for strategic customers.

Document your issue thoroughly and contact our technical support team for assistance.

Yes, several community resources are available for Loongson developers. The Loongson official community forum provides platform for technical discussions and knowledge sharing. GitHub repositories host open-source projects and BSP code. QQ and WeChat groups connect Chinese developers for real-time discussion. Mailing lists are available for specific topics like kernel development and toolchain. Annual Loongson developer conferences provide networking and learning opportunities. As a distributor, we also maintain customer communities for our supported projects. Contact us for community access information.

Join the appropriate community channels for your needs. Contact us for access to distributor-supported communities.

Several debugging tools are recommended for Loongson hardware development. For software debugging, use GDB with JTAG probe for low-level debugging. Serial console (USB-to-UART) is essential for boot messages and console access. Oscilloscope for power rail and signal quality verification. Logic analyzer for protocol debugging (I2C, SPI, etc.). Multimeter for basic voltage and continuity checks. For DDR debugging, some customers use specialized DDR test equipment. Loongson evaluation boards include debug headers for easy access. Our FAE team can recommend specific tools based on your debugging requirements.

Start with basic tools (serial console, multimeter) and add specialized tools as needed for your specific debugging challenges.
