FreeRTOS Resource Management Race Condition in ESP32 | Global Variable Corruption (Demo) | M2L7P1

📘 Description In this lecture, we have explained Resource management. here we have demonstrate a real FreeRTOS race condition on ESP32. Two tasks increment a shared global variable without protection. At first glance, the code looks correct — but due to context switching, the increment operation becomes non-atomic and causes data corruption. We will cover: • What is a race condition? • Why read–modify–write is dangerous • How context switching causes lost updates • Why global variables must be protected • How to fix it using critical sections or mutex This example is part of the FreeRTOS Resource Management chapter. Code demonstrated: Shared global variable Forced context switch using vTaskDelay() Two tasks pinned to the same core Visible counter corruption This is a must-know concept for embedded engineers working with: ESP32, or any RTOS-based system. Stay tuned for the next lecture where we fix this using: • taskENTER_CRITICAL() • Mutex • Priority inheritance If you found this useful, like and subscribe for the complete FreeRTOS series.
