[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
/home/bmentink/amForth/AvrAssembler2/Appnotes\m128def.inc(1140): warning:
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

The warnings can be ignored, they do no harm.

This maillinglist drops attachments. You could send them directly to
me, but I don't have access to a real atmega128, so I cannot test them.

You may double check that you really use the usart0 port. When I got
my first atmega128 style controller board, I connected the usart1 and
programmed usart0. Took a few hours to find out and another one to roll
back the changes I made... :=(
