1、Kernel
The kernel part adjusts the following settings according to the usage requirements:
- Adjust the default stack size space for 64-bit CPUs
- Tick clock adjustment, set the default Tick frequency to 1000Hz
- Add secure STDLIB functions and replace the implementation of STDLIB in the C library by default
- Optimize for scheduling scenarios for multiple threads according to priority and time slice
2、Components
The component section continues to be optimized according to the existing main line, including:
- SFUD updates to accommodate more FLASH
- Continuous updates to the POSIX interface
- Device driver content updates, updates related to serialundefined sdioundefined wlan, and so on
- The AT command is supported as the SERVER side of the network and has been sampled using the ESP8266 module
- Testcase adds C++, a test case for a commonly used interface for POSIX
3、CPU&BSP
Support for BSP:
- Add support for an Infineon development board, the cypress board CY8CKIT-062S2–43012
- Improve qemu emulator and simulator emulator, simulator emulator has been added and adapted to sal functions on Windows and can be used for network programming work
- Maintenance and upgrade of existing BSPs, including ST, WCH, Nuvoton, Nations Technologies, Geehy Semiconductor, ChipOn, and many other development boards
- Compared to the RT-Thread V4.1.0, this version has more support for the Arduino software compatibility layer, several development boards are now supporting the Arduino software
New Added BSP:
- at32f413, at32f415-start, at32f435-start, at32f437-start
