For the last few weeks I’ve been working on porting the BlueSCSI software to the “black pill” F401/F411. Getting close to something usable now (it boots), and it comes with a speed increase.
“Blue pills” will run at about 900k read, 650k write. The black pills run at about 1100k read and 800k write. So, not a huge speed increase but it’s something.
Will be getting some prototype PCBs made for testing in desktops and powerbooks to see if compatibility is different. The higher clock speed and faster response times of the black pills probably mean that timings on the bus have changed, and I don’t really know how well the software complies with standards anyway.
My next targets are probably the STM32L412 and STM32G431, as these are pretty low cost and could be integrated into the board (no more ‘pill module’ required).
