📘 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
