[Amforth-devel] Cannot get serial prompt on an Atmega128 device (STK500/501) development board

[Bernard M. <bme...@gm...>]

Hi All,

I am having lots of problems trying to get amforth running on an ATmega128
on an stk500/501 combo devel board.

My assemble looks ok, output:
----------------------------------------------------
wine ~/amForth/AvrAssembler2/avrasm2.exe -I ~/amForth/AvrAssembler2/Appnotes
-I ~/lib/avra -I ../../core -fI -v1 -W+iw  -e bf.eep.hex -l bf.lst bf.asm
fixme:ntdll:find_reg_tz_info Can't find matching timezone information in the
registry for bias -720, std (d/m/y): 6/04/2008, dlt (d/m/y): 28/09/2008

Register r31 already defined by the .DEF directive
/home/bmentink/amForth/AvrAssembler2/Appnotes\m128def.inc(1141): warning:
Register r30 already defined by the .DEF directive

Assembly complete, 0 errors. 2 warnings
--------------------------------------------------------

I have attached the makefile I used, the custom bf.asm, and the
atmega128.asm file I created.
I have set the fuses to use the internal osc at 8Mhz.

If anyone has the time, please have a look over those files to see if
anything is amis.

I can download the bf.hex file to the device fine, but on hooking up the
RS232 to PE0,PE1 (Rd,Tx) I cannot see any prompt
in minicom (set to 9600 8N1).

Any help much appreciated.

Cheers,
Bernard Mentink
