Jul 1, 2025July 2025 monthly performance summary for levizh/rt-thread. Focused on stabilizing the build and distribution processes across multiple toolchains while expanding hardware support. Key actions: - Implemented WCH UART v2 driver support (drv_usart_v2.c) with conditional inclusion via RT_USING_SERIAL_V2 and Kconfig adjustments to configure DMA and buffer sizes, enabling usage of the newer WCH RISC-V UART in supported builds. - Fixed environment propagation of CPPDEFINES to MDK projects, ensuring correct CPPDEFINES handling across MDK45Project, MDK4Project, MDK5Project, and MDK2Project to prevent missing definitions during builds. - Added a guard in WCH BSP distribution to avoid errors during scons --dist by validating library type is not None before copying, ensuring proper distribution of WCH BSP libraries. - Corrected GD32 driver library Kconfig path to ensure proper sourcing of driver configurations during distribution, reducing packaging-time failures. Overall, these changes improve build reliability, distribution stability, and hardware compatibility, contributing to faster iteration cycles and reduced post-merge defects.
