Re: [Flashforth-devel] arduino

FlashForth needs to write to flash in order to compile new words.

Normally the bootloaders are set up so that only the bootloader can 
write to flash.
And the bootloaders do not have an interface enabling the application 
code to write to flash.

Of course one could write special bootloader that offers what is needed. 
But then you anyway need to program the bootloader first into the chip.
