Re: [Flashforth-devel] FlashForth on the ATmega2560

[Mikael N. <mik...@fl...>]

That is surprising.
On my Arduino Mega2560 board everything works just fine.

I am using exactly the same avrdude command except for stk500 instead of 
usbasp.

Try executing 'empty' as first command. That may help.

Altough the -e chip erase directive should have the same effect as 
executing 'empty' as the first command.
