In order to recompile the espruino code for the STM32F4 board, as Gordon suggests, you need to :
1) change the python definition file.
2) add the define USE_FILESYSTEM=1 in the Makefile
3) modify the spi_diskio.c file and include the management of the SPI peripheral in order to manage the slightly different instructions for the STM32 processors, such alternate function. or OType and PuPd records in the GPIO init port structure.
I succeded in doing the update, but at present time my code has bugs possibly in the C code, do I have to verify using gdb debugger why the code hangs up, as can be seen in the following screenshot. May be that the SPI clock is wrongly set.
