SoC Guide

Hint

The current system does not support automatic detection of chip models. Users need to select the correct chip model through menuconfig before compilation. If the selected model does not match the actual device being programmed, it may lead to hardware functionality issues such as pin multiplexing anomalies. After the system programming is completed, the chip model configured during compilation will be displayed during startup.
