Key Features:

  • (experimental feature) New MCP2515 CAN driver: Introduced a new CAN driver for
    the MCP2515 controller,
    enabling CAN bus communication over SPI. Introduce CONFIG_DEVICE_MCP2515
    configuration option to enable or disable the MCP2515 driver.
  • Documentation Overhaul: Improved documentation across multiple modules, including
    mutexes, semaphores, signals, FIFOs, flags, standard I/O, system time, timers,
    events, atomic operations, idle thread, and various kernel headers.
  • Kernel State Structure: Introduced the z_kernel structure to centralize all
    kernel state variables.
  • Thread Sleep Improvement: Reworked the z_pend_current() function and modified
    k_sleep() to utilize it.
  • Semaphore Enhancement: Added k_sem_cancel_wait() function to allow cancellation
    of threads waiting on a semaphore.
  • Renamed macros:
    • Configuration Options Renaming
      • Renamed several configuration macros for better consistency and clarity:
        • CONFIG_KERNEL_DEBUG to CONFIG_KERNEL_SYSCLOCK_DEBUG=0
        • CONFIG_KERNEL_TIME_SLICE_TICKS to CONFIG_KERNEL_TIME_SLICE_US
        • K_EVENTS_PERIOD_TICKS to Z_EVENTS_PERIOD_TICKS
        • K_TIMERS_PERIOD_TICKS to Z_TIMERS_PERIOD_TICKS
    • SPI Driver Update: Renamed spi_mode_t to spi_role_t and introduced a new
      spi_mode_t for better clarity in the SPI driver.

Minor changes:

  • New Sample: Introduced a hello-world sample to help new users
    get started quickly.
  • Function Relocation: Moved uptime functions to the systime.c file.
  • UART Configuration: Changed the default UART baud rate to 115200 bps for
    consistency across the platform.
  • QEMU Configuration: Defined icount auto in QEMU settings.
  • Makefile Upload Behavior: Adjusted the Makefile to flash the most recently
    built sample when uploading

Bug fixes:

  • I2C Driver Frequency Calculation Fix: Corrected the FREQ_CALC macro to ensure
    accurate frequency settings in the I2C driver.
  • Timer Driver Function Correction: Fixed ll_timer16_start() and introduced
    ll_timer16_get_tcnt().
  • Workqueue Module Macro Fix: Fixed the K_WORK_DELAYABLE_INIT macro and
    reintroduced z_delayable_work_trigger() to restore delayable workqueue functionality.
  • Kernel Synchronization:
    • Scheduler Lock Improvement: Modified the kernel to lock the scheduler only
      if it is not already locked, preventing potential deadlocks.
