hello
i need your help to port ez328mon to palm105 (that is equipped with mc68ez328)
i am developing a lot with palm m105: i'm able to bootstrap it into the special
bootstrap serial mode, so i can upload a new firmware :P
i need to know about how to correctly set the memory layout, 'cause i've same
issus. Also do you know about 68ez328 mon ?
can you help me ?
let me know
regards

68EZ328 Monitor Program
Version 0.04

Feb 29, 2000
This is a monitor program that runs on the 68EZ328 CPU. It
requires a version of m68k-coff-gcc to compile, but if you
don't need to recompile you can use the supplied binary,
'monitor.srec'
_Make sure_ to look at the code in board.ld and board-init.S!
This defines the memory and peripherals connected to your CPU.
Unless your memory configuration is just like mine (2meg flash,
8meg DRAM, same timings, etc...) you WILL need to recompile!
It does:
program and erase flash memory
transfer s-records and binary files at up to 115kbps
allow you to test your hardware
use interrupt-driven buffered serial I/O
use interrupt-driver PWM sound playing
It does not:
run from flash memory
have very good applications

compiling sources, i find error with board.ld
m68k-elf-ld: section .rodata [00000000 -> 00000923] overlaps section .text

has somebody ported ez328 mon to palm m105 ?
could somebody understand how to fix the problem ?
regards
this is the board.ld (linker script)
