Re: [Flashforth-devel] Warnings from assembler

[Helge K. <Hel...@gm...>]

Hi Mikael,

I have pulled the latest commit 73aba62 from November 11th. This
includes HEX files for the AVR targets. I expected that the same
sequence of avrdude commands should prepare my Arduino with a running
system.

avrdude -cusbasp -pm2560 -Ulock:w:0x3F:m -Uefuse:w:0xFD:m
-Uhfuse:w:0xD8:m -Ulfuese:w:0xFF:m
avrdude -cusbasp -pm2560 -Uflash:w:2560-16MHz-38400.hex:i -Uhfuse:w:0xD8:m

With the version from commit c947663 (2022-04-26) I get the output in
the terminal:

E FlashForth 5 ATmega2560  18.11.2020

Is my expectation invalid to get a similar output with the latest HEX
file? I don't see any output with the latest files.

Can you recommend how to bring the current version to the Arduino 256
target?

Best regards,
Helge

This sequence works with the files f
