STM32 Tutorial #32 – HIDDEN Treasure CCMRAM

In this video we will find hidden treasure by exploring the CCMRAM feature of the STM32F40x MCU’s and use that RAM for the FreeRTOS heap. We will also be using the Independent Watchdog (IWDG) with FreeRTOS.

DISCLAIMER: I make one big mistake in this video. On the STM32F4, the CCMRAM can NOT be used for code!

The Core Coupled Memory (CCMRAM) is documented here: https://stm32world.com/wiki/Core_Coupled_Memory
