This article describes the common debugging and adaptation methods for adapting I2C sensors based on the .

This article explores how PowerLeader Computer System Co., Ltd. successfully implemented an in-house developed Human-Machine Interface (HMI) solution leveraging the openUBMC framework. You will know the technical architecture, design principles, and implementation strategies behind PowerLeader's smart UART HMI. As a critical component within the openUBMC ecosystem, this solution demonstrates advanced engineering practices and serves as a practical guide for developers.

This tutorial provides a hands-on guide based on EJBCA, designed to compliance the CA/RA workflow in a demo environment. It walks through key operational steps including certificate profile creation, end entity profile configuration, approval process activation, and RA certificate issuance and download. This tutorial focuses on practical execution, making it ideal for experiments, proof-of-concept (PoC) setups, or internal demonstrations. Please note that this tutorial does not cover production-level security hardening or compliance requirements.

As digital transformation surges forward, system complexities escalate continuously. The efficient monitoring and management of distributed systems have become a key challenge. As a bridge between hardware and software, the baseboard management controller (BMC) is responsible for device management, monitoring, and maintenance. openUBMC 25.06 introduces the Observability component to provide complete observability capabilities based on openTelemetry, enabling developers to clearly understand system status, quickly locate issues, and optimize system performance.

NCSIis a critical protocol enabling communications between the baseboard management controller (BMC) and the network controller. During the development of the openUBMC 25.06 version, I encountered several bottlenecks:

In software development, the build phase is critical because it directly impacts development efficiency and software quality. To support local deployment of openUBMC and improve development efficiency within the enterprise, Yangtze Computing has introduced a developer build solution and a pipeline build solution. The offline deployment–based solutions cover infrastructure configuration and build system design, helping gain a deep understanding of how to construct and optimize the openUBMC build system.

openUBMC 开源社区按照不同的SIG（Special Interest Group）来组织开发及版本相关工作。

openUBMC supports QEMU simulation and debugging. However, there is no efficient debugging method for hardware debugging. After trying many development boards, I summarized some openUBMC startup experience based on the MYC-LHi3093 development board for your reference.

In today's complex and evolving network security landscape, firmware has become a prime target for attackers, with security threats on the rise. As the foundational layer of a computing system, firmware plays a critical role in the overall security and resilience of the system. Given its position at the lowest layer and its high-level privileges, a compromised firmware can render upper-layer protections ineffective. Therefore, enhancing the security and resilience of firmware is of paramount importance in the current threat environment.
