API Changes

---

Deprecated in this release

• Settings

  • SETTINGS_USE_BASE64, encoding values in base64 is marked for removal.

Stable API changes in this release

• GPIO

  • GPIO API has been reworked to support flags known from Linux DTS GPIO bindings. They will typically be defined in the board DTS file

    • GPIO_ACTIVE_LOW, GPIO_ACTIVE_HIGH used to set pin active level
    • GPIO_OPEN_DRAIN, GPIO_OPEN_SOURCE used to configure pin as open drain or open source
    • GPIO_PULL_UP, GPIO_PULL_DOWN used to configure pin bias

  • Reading / writing of pin logical level is supported by gpio_pin_get, gpio_pin_set functions.

  • Reading / writing of pin physical level is supported by gpio_pin_get_raw, gpio_pin_set_raw functions.

  • New set of port functions that operate simultaneously on multiple pins that belong to the same controller.

  • Interrupts should be configured by a dedicated gpio_pin_interrupt_configure() function. Configuring interrupts via gpio_pin_configure() is still supported but this feature will be removed in future releases.

  • New set of flags allows to set arbitrary interrupt configuration (if supported by the driver) based on pin physical or logical levels.

  • New set of flags to configure pin as input, output or in/out as well as set output initial state.

  • Majority of the old GPIO API has been deprecated. While the care was taken to preserve backward compatibility due to the scope of the work it was not possible to fully achieve this goal. We recommend to switch to the new GPIO API as soon as possible.

  • Areas where the deprecated API may behave differently to the original old implementation are:

    • Configuration of pin interrupts, especially involving GPIO_INT_ACTIVE_LOW and GPIO_POL_INV flags.
    • Behavior of gpio_pin_configure() when invoked without interrupt related flags. In the new implementation of this deprecated functionality the interrupts remain unmodified. In the original implementation some of the GPIO drivers would disable the interrupts.

  • Several drivers that rely on the functionality provided by the GPIO API were reworked to honor pin active level. Any external users of these drivers will have to update their DTS board files.

    • bluetooth/hci/spi.c
    • display/display_ili9340.c
    • display/ssd1306.c
    • ieee802154/ieee802154_mcr20a.c
    • ieee802154/ieee802154_rf2xx.c
    • lora/sx1276.c
    • wifi/eswifi/eswifi_core.c
    • majority of the sensor drivers

• PWM

  • The pwm_pin_set_cycles(), pwm_pin_set_usec(), and pwm_pin_set_nsec() functions now take a flags parameter. The newly introduced flags are PWM_POLARITY_NORMAL and PWM_POLARITY_INVERTED for specifying the polarity of the PWM signal. The flags parameter can be set to 0 if no flags are required (the default is PWM_POLARITY_NORMAL).
  • Similarly, the pwm_pin_set_t PWM driver API function function now takes a flags parameter. The PWM controller driver must check the value of the flags parameter and return -ENOTSUP if any unsupported flag is set.

• USB

  • The usb_enable() function, which was previously invoked automatically by the USB stack, now needs to be explicitly called by the application in order to enable the USB subsystem.
  • The usb_enable() function now takes a parameter, usb_dc_status_callback which can be set by the application to a callback to receive status events from the USB stack. The parameter can also be set to NULL if no callback is required.

• nRF flash driver

  • The nRF Flash driver has changed its default write block size to 32-bit aligned. Previous emulation of 8-bit write block size can be selected using the CONFIG_SOC_FLASH_NRF_EMULATE_ONE_BYTE_WRITE_ACCESS Kconfig option. Usage of 8-bit write block size emulation is only recommended for compatibility with older storage contents.

• Clock control

  • The callback prototype (clock_control_cb_t) has now additional argument (clock_control_subsys_t) indicating which clock subsystem got started.

Removed APIs in this release

• Shell

  • SHELL_CREATE_STATIC_SUBCMD_SET (deprecated), replaced by SHELL_STATIC_SUBCMD_SET_CREATE
  • SHELL_CREATE_DYNAMIC_CMD (deprecated), replaced by SHELL_DYNAMIC_CMD_CREATE

• Newtron Flash File System (NFFS) was removed. NFFS was removed since it has serious issues, not fixed since a long time. Where it was possible NFFS usage was replaced by LittleFS usage as the better substitute.

Kernel

---

• Addressed some race conditions observed on SMP-enabled systems
• Propagate a distinct error code if a workqueue item is submitted that has already been completed
• Disable preemption when handing fatal errors
• Fix an issue with the system call stack frame if the system call is preempted and then later tries to Z_OOPS()
• add k_thread_stack_space_get() system call for analyzing thread stack space. Older methods which had problems in some cases or on some architectures like STACK_ANALYZE() are now deprecated.
• Many kernel object APIs now optionally return runtime error values instead of relying on assertions. Whether these return values, fail assertions, or do no checking at all is controlled by the new Kconfig options ASSERT_ON_ERRORS, NO_RUNTIME_CHECKS, RUNTIME_ERROR_CHECKS.
• Cleanups to the arch_cpu_start() API
• Spinlock validation now dumps the address of the incorrectly used spinlock
• Various improvements to the assertion mechanism
• k_poll() may be passed 0 events, in which case it just puts the caller to sleep
• Add k_thread_foreach_unlocked() API
• Add an assertion if k_sleep() is called from an ISR
• Numerous 64-bit fixes, mostly related to data type sizes
• k_mutex_unlock() is now correctly a rescheduling point
• Calling k_thread_suspend() on the current thread now correctly invokes the scheduler
• Calling k_thread_suspend() on any thread cancels any pending timeouts for that thread
• Fix edge case in meta-IRQ preemption of co-operative threads
