Hi All,

Does anyone have non-HAL firmware code dump for STM32F427 or STM32F4xx series controller for doing low level verification. Please share the zip file or link if anyone have it. Thanks in advance. #dfu #stm32 #firmware #linux

There's the DSP (Firmware) Library, or you can write registers directly yourself by reviewing and using the Reference Manual for the part.

I don't recall there being a self-test / validation library. Perhaps you should call you local ST rep or FAE.

No the RED DOWNLOAD button at the bottom of the page is for the original firmware library code, not HAL/CUBE

It is still an abstraction layer, if you want bare metal access to the peripherals you're going to have to learn how to code at the register level, and use the Reference Manual to help you understand them at a bit level.
