 Hi Mikael,
 exactly that was exact my fault. I tried it again, uploaded
 the flash data first and then the eeprom data with the same
 result as bevore. Then I tried it viceversa uploaded the
 eeprom data first and then the flash and that led to
 success.
 I then tried the classical LED blink program:
 
 marker -blink
 $24 constant DDRB
 $25 constant PORTB
 : led-init $20 DDRB c! ;
 : led-on $20 PORTB c! ;
 : led-off $0 PORTB c! ;
 : led-blink for led-on 100 ms led-off 100 ms next ;
 
 That works fine so far but not at the first try. I first
 used DDRB=0x04 and PORTB=0x05 like it was defined in
 m328Pdef.inc. After some investigation I found that for most
 AVR devices, the IO register space is mapped into the data
 memory address space with an offset of 0x20 since the bottom
 of this space is reserved for direct access to the MCU
 registers.
 
 Do you have plans to add an assembler, like in the PIC
 implementation, for the avr flashforth ?
 
 thanks for helping
 Sven
