GoKawiilDeveloper details hands-on tests of ST's STM32MP2 microprocessor and FPGA pairing
A hardware blogger has published a long-delayed write-up on experimenting with the STM32MP2, discussing prior work combining STM32 microcontrollers with FPGAs and the routing challenges of the STM32H7's FMC bus on low-cost boards. The post also references a silicon security bug the author discovered in an ST chip, which was disclosed only after ST issued an advisory.
GoKawiil's interpretation of the reporting above, not reported fact.
The delayed disclosure suggests the author coordinated responsibly with ST before publishing technical details, which is a common practice in hardware security research. The broader discussion of pin layout and routing difficulty highlights ongoing tradeoffs engineers face when combining MCUs and FPGAs on budget PCB fabrication processes.
- Blog post was delayed due to a silicon security bug the author found in an ST chip
- Author has long sought an MCU with simpler FPGA integration than the STM32H7's FMC
- STM32MP2 is being evaluated as a potential solution to prior routing complexity
STM32MP257 Discovery Kit — If you're experimenting with the STM32MP2 line like in this post, the official Discovery Kit is the easiest way to get hands-on with the chip's FMC interface, high-speed peripherals, and Cortex-A/M combo. It's a great platform for prototyping FPGA pairing projects and exploring the same kind of pin-mapping quirks discussed in the article.
