Worked on the flipperdevices/u-boot repository to enhance UART reliability by standardizing the default baud rate to 115200 across all configuration files and device tree sources. This change addressed baud-rate mismatch issues that can occur during boot and debugging, improving both data throughput and consistency across device builds. The approach involved careful configuration management and device tree programming using C, ensuring that all relevant files reflected the new standard. By focusing on embedded systems best practices and leveraging Git for traceability, the work streamlined development, validation, and device provisioning processes, resulting in more reliable and efficient embedded device operation.
