Error in main.c for banked flash tutorial (19.ogg)

[cejay]

hello Navid.
could I ask for a little help? I followed your tutorial for banked
flash very leniently. However I get an error saying the following.

make all
m68hc11-gcc -m68hc12 -mshort -mlong-calls -g -Os -Wall -Wmissing-
prototypes -Wno-char-subscripts -fomit-frame-pointer -msoft-reg-
count=0 -mauto-incdec -I. -I./includes -c -o main.o main.c

addresses 0xffff0000 main.elf main.s19 ; cp main.s19 000.s19 ; cp
main.s19 .000.s19 ;

I think the error lies on the linking part. I already checked the
files. please help.

Hi Jonathan,

Quick solution:

Dwnload my pre-compiled version and unzip:
http://gcc-hcs12.com/downloads/GNU%20Development%20Tool%20Chain/LINUX/DEB/GNU%20Development%20Tool%20Chain%20-%20Extracted%20DEB.zip

Open a shell run bash and run: export PATH="$HOME/Desktop/GNU
Development Tool Chain - Extracted DEB/usr/bin:$PATH"

and while remaining in the same bash shell go to
HCS12_16_FLASH_BANCKED and run "make clean; make"

====================

Details:

I've downloaded Ubuntu 8.10 CD Live and used 'sudo apt-get install
binutils-m68hc1x gcc-m68hc1x gdb-m68hc1x newlib-m68hc1x' ...

I have got the same warnings:

There should be something wrong with the linker ...


When I use Ubuntu 7.04 or our CENTOS and patch the gcc and compile
from scratch using x86-GCC 3.4.6 everything is fine (below), but as
soon as I come to Ubuntu 8.04 and its x86-GCC 4.2.4 I get the above
problems ...

sudo apt-get install build-essential
sudo apt-get purge binutils-m68hc1x gcc-m68hc1x gdb-m68hc1x newlib-
m68hc1x

# now run the attached commands (use bash)

# after everything is done, download http://gcc-hcs12.com/downloads/HCS12_16_FLASH_BANCKED.zip
and make sure to change the followings in the MAKEFILE
CC=/tmp/navid/gnu-hcs12/usr/bin/m6812-elf-gcc
AS=/tmp/navid/gnu-hcs12/usr/bin/m6812-elf-as

OC=/tmp/navid/gnu-hcs12/usr/bin/m6812-elf-objcopy
OD=/tmp/navid/gnu-hcs12/usr/bin/m6812-elf-objdump

then try "make clean; make" everything should work fine ...
