Problem programing Flash

So I did some more digging and now know that the GDB debug script 
doesn't automatically program flash.

The real problem is how to program the flash. Does anyone have a 
complete example showing how to do this? Something like the Yagarto 
tutorial on Ram debugging is what I'm looking for. While Jim Lynch's 
tutorial is great, it's now out of date with the latest OOCD release.

I've tried several approaches and nothing seems to work. Any help would 
be greatly appreciated.

When using the OpenOCD target-library and the defaults the flash can be 
written with gdb's load command. It has been some time since I played 
around with AT91SAM7SE, OpenOCD and Eclipse so this may be outdated too 
and not the best solution:

OpenOCD start (external tools):
openocd.exe -d1 -f interface/jtagkey.cfg -f openocd.cfg

openocd.cfg-file:
debug_level 3
fast disable
jtag_speed 200
jtag_nsrst_delay 200
jtag_ntrst_delay 200
script target/eir-sam7se512.cfg
jtag_khz 6000
fast enable
init
debug_level 1


Eclipse GDB Hardware Debugging:
C/C++ application: xxxx.elf ("Project binary")
gdb-command: arm-none-eabi-gdb (or arm-elf-gdb)
use remote, device generic, localhost, port 3333
startup: all checkboxes off,
Init-commands:
 monitor debug_level 3
 monitor soft_reset_halt
 monitor flash probe 0
 load
 monitor soft_reset_halt
 set mem inaccessible-by-default off
 monitor debug_level 1
Run-Commands:
 stepi

Thanks for the helpful suggestions, Martin.

I must admit I haven't tried them yet, however. Since they seem to be a 
very simple approach, I plan to try them.

Here's what I did do instead. While I was waiting for a reply to my 
earlier email, I discovered this site:

http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/openocd_intro/index.html#at91sam7int

(I assume that you are the same Martin Thomas, no?) Anyway, I used the 
scripts shown there and updated them to use the most recent OOCD 
commands and it all worked (after a little tweaking). There are now just 
two files - one called from Make, and one called as a script file by the 
first one.

I've left lines from the original files so you can see what's changed. 
These worked and programmed my Flash perfectly. Hopefully, these will 
help others.
