Porting Espruino on STM32F415RG : questions on board file options

Hi,

There is now Espruino WiFi which has more RAM and Flash available, so that could be an easy option ;)

There are also some things you can do to get your code size down so it might fit into a Pico...

But...

• 'bootloader' : 1 uses the Espruino bootloader (which lets you update firmware over USB serial). I'd set this to 0 and upload code with ST-LINK or DFU as if you set it to 1 you have to compile your own bootloader too. If setting to 0 I'd start from a board.py of a file with bootloader:0 too as some addresses change
  
• 'speed' : 84" it's the speed in MHz
  
• Yes, saved_code allocates an area of flash where the contents of RAM can get saved to.
  
  

Could you advice me on the best way to use the flash pages structure ?

If you have lots of flash, just use a single large flash page at the end of memory. Anything else gets really difficult...
