This is a different matter.The page needs to be re-ordered so the concepts are introduced one by one.

It’s a form of simple service announcement. This commit was created on GitHub.com and signed with a How do we say "Tickless mode is enabled by default for bare metal profile"?You are correct. The mbed-os-5.15 documentation says this: where it specifies that nullptr is returned if in ISR context. Now scheduler schedules idle thread to run as two threads are in the wait state. SysTick is never used in bare metal.This provides the marshalling point for a system global SysTimer, which is used to provide:Bare metal uses SysTimer to implement timed sleeps. Updated tickless mode porting guide with missing information and done some cleanup.

This idle thread put the system to sleep. This comment has been minimized. I will now try to dig onwards and see what I can come up with.I have actually no idea how that evet queue is supposed to work, I must be holding it totally wrong.This works without crashes.

DEPENDS ON ARMmbed/mbed-os-examples-docs_only#115 This work is initially intended to borrow part of #1216 to Application flow control - credits to @cvasilak. When SysTick timer expires on its own or from an external event like interrupt, then it exits sleep mode and re-enables the SysTick.To enable tickless mode in Mbed OS, your target has to meet following requirements:If the target supports both low power and microsecond ticker, then low power ticker is selected with tickless mode.For instance, the system runs only with two threads thread 1 and thread 2.

For instance, the system runs only with two threads thread 1 and thread 2.During the first 2 tick interrupts thread 1 and thread 2 schedules alternatively.

You can also let the other threads run longer by increasing the sleep time of the There isn’t much memory, so keeping threads to a minimum is paramount. Target in tickless mode normally disables the SysTick, sets up wake-up timers and enters sleep mode when idle. But will soldier on. Now scheduler schedules idle thread to run as two threads are in the wait state. The periodic tick configures as 1ms for Mbed OS.Tickless mode is an optimization mechanism to suspend the SysTick timer. Running all Mbed OS tests suits, with particular focus on HAL sleep and HAL low power ticker tests, provides sufficient coverage.Tickless mode is an optimization mechanism to suspend the SysTick timer. All previous Systick wake-ups waste power.Targets supporting tickless mode override the default SysTick mechanism and use the [Targets supporting tickless mode override the default SysTick mechanism and use the [Tickless mode is enabled by default for bare metal profile without adding Tickless mode is enabled by default for bare metal profile without adding There are no dedicated tests validating tickless mode.

Some of the explanations around Ticker and Thread are taken from there. Now scheduler schedules idle thread to run as two threads are in the wait state. This comment has been minimized.

All previous Systick wake-ups waste power.But with tickless mode, it suspends the SysTick periodic wake up as no threads are ready to run for quite some time which inturn saves the power.Targets supporting tickless mode override the default SysTick mechanism and use the [Tickless mode is enabled by default for bare metal profile without adding There are no dedicated tests validating tickless mode.

Are we sure that the current HAL tests provide enough coverage?What is missing at the end is some notes on current issues/challenges with tickless. Target in tickless mode normally disables the SysTick, sets up wake-up timers and enters sleep mode when idle. This is a different matter.This paragraph might need rewriting. I would assume it to be totally impossible for a call to Thank you for the help and for following my adventures this far.
