Using VERBOSE=1 to show the commands make is running, I see that the top level include directory is not present in the compiler arguments for amazon-freertos objects. WebMay 1, 2024 · The timer setup and interrupt is what allows the FreeRTOS kernel to select a different task (“context switching”) and execute other stuff, regardless of what’s being currently executed, since the timer interrupt interrupts everything. You can see that clearly in e.g. github.com

WebJan 1, 2024 · However, after looking into FreeRTOS source, in cases like this (unblocking higher priority task from ISR), they also set an internal flag xYieldPending, which gets periodically checked inside xTaskIncrementTick, called from your timer interrupt. This way however probably means the context switch will happen slightly delayed. WebThe new code ensures xTickCount reaches xNextTaskUnblockTime inside xTaskIncrementTick () instead of inside vTaskStepTick (). This fixes the typical case where a task wakes up one tick late and a rare case assertion failure when xTickCount\ rolls over.
