pic24 board always compiles to flash

[ronny suy]

Hi Mikael,
I played with ff5 on the curiousity board. It works well ! But I dicovered that new defenitions are seemingly always compiled to flash. (the prompt shows ok, ram)
Because after a reset or even a powercycle , the defenitions are still in memory.
I assume this isn't normal behaviour.
What could cause this ?

Regards,

That is the normal behaviour. On the PIC24 the code can only be executed from flash, so it is always compiled to flash. The prompt tells you where data is located.

So

ram variable ramvar

compiles a variable named ramvar to flash which stores its data in ram.

eeprom variable eepromvar
flash variable flashvar

These store the data in eeprom and flash. Remember that flash and eeprom have limited write endurance.

I recommend reading flashforth.com
