I have a 32F412GDISCOVERY (the one with LDC) board and the stock demonstration firmware is nowhere to be found. I can find the firmware to other discovery boards, but not this one. How can I obtain this firmware source code package?

Just pulled Cube F4 v1.16, and built with Keil uV5.22

Doesn't have a Flash Algorithm for the SPI NOR Flash at 0x90000000, so used the ST-LINK Utilities to burn instead of Keil, but seems to run without faulting.

Now migrated the current FatFs release supporting FATX, will need to benchmark with some 64 or 128GB cards

Just been through the F412G-DISCO code and there is some awfully broken DWT->CYCCNT code in there. HAL_GetTick() doesn't wrap properly in the 32-bit number space.

Probably a wise move, better you build your apps the way you are comfortable with, and strip out the pieces you need from demo/example code as you need to, rather than try and add stuff into code built with a different mindset.
