Hi

My board is http://www.olimex.com/dev/index.html (Olimex - SAM7-EX256)

I need some help in flashing programming part in make file .


In make file with c++ programs support from winArm projects page i made
some changes in flashing part for example like this:

ifeq ($(FLASH_TOOL),OPENOCD)

# Program the device with Dominic Rath's OPENOCD in "batch-mode", needs
cfg and "reset-script".

program:

$(TARGET).$(IMGEXT)
@echo

@echo "Programming with OPENOCD"

C:\Program Files\openocd-2006re115\bin\openocd-ftd2xx.exe -f
at91sam7x256-armusbocd-flash-program.cfg

endif

Then when i say build make target it gives the following error


make -k program
The system cannot find the path specified.
ECHO is off.
"Programming with OPENOCD"
C:\Program Files\openocd-2006re115\bin\openocd-ftd2xx.exe -f
at91sam7x256-armusbocd-flash-program.cfg
Info:    openocd.c:82 main(): Open On-Chip Debugger (2006-10-12 18:00
CEST)
Error:   configuration.c:122 parse_config_file(): couldn't open config
file
make: *** [program] Error 1


I dont know how to add reset script overthere i tried but no use it
gives the same error.


I tried to change it with other flash programming part which i use in
the make file for C programs:

for example like this:

#

#                            FLASH PROGRAMMING      (using OpenOCD and
Amontec JTAGKey)
#
# Alternate make target for flash programming only
#
# You must create a special Eclipse make target (program) to run this
part of the makefile
# (Project -> Create Make Target...  then set the Target Name and Make
Target to "program")
#
# OpenOCD is run in "batch" mode with a special configuration file and a
script file containing
# the flash commands. When flash programming completes, OpenOCD
terminates.
#
# Note that the make file below creates the script file of flash
commands "on the fly"

# specify output filename here (must be *.bin file)
#TARGET = main.bin

# specify the directory where openocd executable resides
(openocd-ftd2xx.exe or openocd-pp.exe)
OPENOCD_DIR = 'C:\Program Files\openocd-2006re115\bin\'

# specify OpenOCD executable (pp is for the wiggler, ftd2xx is for the
USB debugger)
#OPENOCD = $(OPENOCD_DIR)openocd-pp.exe
OPENOCD = $(OPENOCD_DIR)openocd-ftd2xx.exe

# specify OpenOCD configuration file (pick the one for your device)
OPENOCD_CFG = $(OPENOCD_DIR)at91sam7x256-armusbocd-flash-program.cfg

# specify the name and folder of the flash programming script file
OPENOCD_SCRIPT = c:\temp\temp.ocd

# program the AT91SAM7S256 internal flash memory
program: $(TARGET).$(IMGEXT)
 @echo "Preparing OpenOCD script..."
 @cmd /c 'echo wait_halt > $(OPENOCD_SCRIPT)'
 @cmd /c 'echo armv4_5 core_state arm >> $(OPENOCD_SCRIPT)'
 @cmd /c 'echo flash write 0 $(TARGET) 0x0 >> $(OPENOCD_SCRIPT)'
 @cmd /c 'echo mww 0xfffffd08 0xa5000401 >> $(OPENOCD_SCRIPT)'
 @cmd /c 'echo reset >> $(OPENOCD_SCRIPT)'
 @cmd /c 'echo shutdown >> $(OPENOCD_SCRIPT)'
 @echo "Flash Programming with OpenOCD..."
 $(OPENOCD)  -f $(OPENOCD_CFG)
 @echo "Flash Programming Finished."


When i use this the problem here is its flashing the main.cpp program
for around 130 seconds and says flashing complete and nothing happens.
The problem with this script is its flashing the .cpp file instead of
.bin file .You can see above #TARGET = main.bin , i commented this
because in the script of makefile we already have TARGET = main command.

But here IMGEXT means bin declared i dont understand why its taking just
the main file $(TARGET).$(IMGEXT)

So there's a kind of conflict .

Here is the complete makefile:
# Hey Emacs, this is a -*- makefile -*-
#
# WinARM template makefile
# by Martin Thomas, Kaiserslautern, Germany
# <eversmith@heizung-thomas.de>
#
# based on the WinAVR makefile written by Eric B. Weddington, Jörg
Wunsch, et al.
# Released to the Public Domain
# Please read the make user manual!
#
#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make program = Download the hex file to the device
#
# (TODO: make filename.s = Just compile filename.c into the assembler
code only)
#
# To rebuild project do "make clean" then "make all".
#

Hi

I changed the above line something like this

'C:\Program Files\openocd-2006re115\bin\'openocd-ftd2xx.exe -f
'C:\Program
Files\openocd-2006re115\bin\'at91sam7x256-armusbocd-flash-program.cfg

Now flashing seems to work. There was just missing ' '.

But nothing happens with my main file. I think i need to rework on c++
programs . The same file in c works fine when i flash my board but i
tried to flash the same program converted into c++ now it doesn't work.

Anyone programming in c++ with ARM SAM7X256 Olimex Board ?

Please let me know. It will be of great help to me.

Regards
Rajitha
