RT-Thread v4.0.0 Released

The following is the change log of this version since v3.1.1 release.

Kernel

  • Add SMP support;
  • Add support for 64-bit processors;
  • When the thread is running on CPU, the state of this thread is changed to RUNNING stat instead of READY state in previous version;

Components

  • When formatting the file system, adds FM_SFD option to create a volume in SFD format for FatFs; (HubretXie)
  • Add file system handle pointer in `struct dfs_fd' structure;
  • Fix stdio fd issue when POSIX api is used; (gbcwbz)
  • Fix the fd_is_open() issue: when the sub-path is the same in different mounted filesystem.
  • Change the critical lock/unlock to dfs_lock/unlock in getcwd() function of DFS (the critical lock/unlock is different in SMP environment);
  • Rewrite list_thread/list_* implementation of finsh cmd to avoid multi-core competition case;
  • Fix the aio_result issue, which is returned by aio_read_work in AIO; (fullhan)
  • Fix the mmap issue when the addr parameter is NULL; (fullhan)
  • Modify the _sys_istty function in armlibc to correctly handle STDIN/STDOUT/STDERR; (gbcwbz)
  • Modify the _write_r function in newlib to correctly handle stdout.
  • Add lightweight processes (lwP) and corresponding system calls;
    • the lwP user application environment will be added later;
  • Fix the at_socket issue when socket is a null pointer; (thomas onegd)
  • Fix the select event issue in at_recvfrom() function in at_socket;
  • Divide SAL into sal_socket_ops/sal_proto_ops and sal_proto_ops is implemented with gethostbyname/getaddrinfo ops etc.
  • Add socket TLS layer in SAL, that is, upper application can be supported by encrypted transmission without considering lowlevel TLS at all.
  • Fix the length issue of ulog_strcpy, which should be not exceed ULOG_LINE_BUF_SIZE;
  • Add the macro definition of hexadecimal log output to ulog; (HubretXie)
  • Add uTest component. The uTest is a unit test framework on RT-Thread, and can also be used for automatic testing on board with external Python scripts.
  • Fix some compilation warnings and enumeration mismatches in drivers/audio;
  • Fix the can_rx/can_tx issue, which is not cleared to NULL when CAN device is closed in drivers/can; (xeonxu)
  • Fix drivers/hwtimer, time acquisition issue with counting down mode;
  • Add drivers/adc driver framework;
  • Fix the tick compensation issue when enable interrupt too early; (geniusgogo)
  • Add RT_SERIAL_USING_DMA option in drivers/serial;
  • Add QSPI support in drivers/spi framework;
  • Add QSPI support in SFUD (based on the QSPI peripheral of stm32); SFUD is upgraded to version 1.1.0;
  • Optimize SPI take/release function call in spi_msd;
  • Fix the blk_size issue in rt_rbb_blk_alloc();
  • Fix the FS USB issue in _get_descriptor function;
  • Fix the empty password issue in AP mode of drivers/wlan;
  • Fix the return type issue in drivers/wlan;
  • Remove the duplicate opening file check when open a file;

BSP

  • Change the name parameter to cosnt char * in rt_hw_interrupt_install function; (liruncong)
  • Rewrite the RISC-V porting layer to make as a common and standalone porting layer for RISC-V IMAC 32/64;
  • Fix $ warning issue in Kconfig files of each BSP;
  • Add the LPC54114-lite BSP, including GPIO, I2C, SDCard, SPI, SPI Flash, UART driver;
  • Add Nuvoton-M487 BSP, including UART, EMAC driver; (Bluebear 233)
  • Add Kendryte K210 BSP with RISC-V64 dual-core SMP BSP, including UART driver, also verified with micropython;
  • Add RV32M1 VEGA BSP, including GPIO, I2C, SDCard, UART and other drivers;
  • Fix the CAN driver issue in STM32F4XX-HAL BSP; (xeonxu)
  • Fix UART DMA settings issue in STM32F10x/STM32F40x BSP; (zhouchuanfu)
  • Fix the HEAP_BEGIN definition issue in STM32H743-Nucleo BSP; (nongxiaoming)
  • Fix GPIO configuration issue in stm32f10x-HAL; (Wu Han)
  • Change stm32f107 BSP as main function entry; (whj4674672)
  • Fix the serial interrupt handling issue in stm32f10x BSP;
  • Add PWM, RTC and watchdog drivers to stm32f10x-HAL BSP; (XXXXzzzz000)
  • Fix the watchdog driver issue in stm32f4xx-HAL BSP; (XXXXzzzz000)
  • Use lwIP version 2.x in stm32f40x/stm32f107 BSP.
  • Fix the link issue when enable cmBacktrace package in stm32f4xx-HAL BSP; (xeonxu)
  • Support Audio and microphones features in stm32f429-apollo BSP;
  • Enable dlmodule support in x86 BSP; (SASANO Takayoshi)
  • Addd uTest section in the link script of qemu-vexpress-a9/stm32f429-atk-apollo BSP for automatic testing;
  • Change the license to Apache License v2.0 in Godson 1C BSP; (sundm75)
  • Add the new BSP framework for STM32 serial chip, such as STM32 G0/F0/L0/F1/F4/F7/H7. In new BSP framework, the SoC drivers is reused. And in same time, lots of STM32 boards are supportted with new BSP framework:
