Our Verdict

The STM32Fx Microcontroller Custom Bootloader Development course on Udemy provides an extensive look into creating your own bootloader for the STM32F446 MCU. While it delves deep into flash handling implementations and code explanations, it falls short on theoretical background and broader communication protocol support. However, if you're looking for a hands-on approach to ARM Cortex Mx bootloaders, this course will serve as a solid starting point.

What We Liked

In-depth explanations of STM32Fx microcontroller bootloader development, covering essential aspects like host communication implementation, custom command packets, and different boot modes.
Comprehensive flash handling implementations, including sector erase, program, mass erase, and vector table relocation for ARM Cortex Mx processors.
Well-structured course with real-world application examples that walk you through the code and hardware-related information, enabling a clear understanding of how bits come together.

Potential Drawbacks

Limited focus on theoretical aspects such as memory organization, Main Stack Pointer (MSP), reset vector, heap, and stack operation.
Course is tightly coupled with the STM32F446 MCU; a cross-manufacturer comparison of bootloader implementations would be beneficial.
Minimal coverage of other communication protocols for flashing, such as CAN or SD card support.
