Hi there!
I've got myself a Blackpill board which is based on the same STM32F4-family MCU. Given it's the same architecture, I thought it'll be easy to port hydrafw to this board. F411CE has lower speed (100Mhz) and less peripherals, so I had to adjust the code a bit to make it work. I've tested the firmware on the device and it works fine. I wasn't able to verify all modes, but UART, ADC, GPIO seem to work.
flashrom
recognizes the device as well, but I haven't yet read a flash chip over SPI, probably due to bad contact when using a test clip.debug timing
command hangs the MCU, not sure what to make of it.If you're willing to accept such addition to your project, we can work on cleaning this WIP branch and making the code open to run on other boards.
