Hi!
I am trying to configure openocd to run it fom my Makefile.
Running it manually works:
===== begin openocd session =====
% nc localhost 4444
��������Open On-Chip Debugger
> halt
halt
target state: halted
target halted in ARM state due to debug-request, current mode:

I used the configs from:
scripts/interface/olimex-arm-usb-ocd.cfg
scripts/target/sam7se512.cfg (modified for se256)
and a board-config that basically contains "reset_config srst_only
srst_pulls_trst"
Now I am trying to write a script to run from a Makefile.
===== begin openocd script =====
proc mt_flash_bin {IMGFILE} {
# disable watchdog
mww 0xfffffd44 0x00008000
# enable user reset
mww 0xfffffd08 0xa5000001
# CKGR_MOR : enable the main oscillator
mww 0xfffffc20 0x00000601
sleep 10
# CKGR_PLLR: 96.1097 MHz
mww 0xfffffc2c 0x00481c0e
sleep 10
# PMC_MCKR : MCK = PLL / 2 ~= 48 MHz
mww 0xfffffc30 0x00000007
sleep 10
# MC_FMR: flash mode (FWS=1,FMCN=60)
mww 0xffffff60 0x003c0100
sleep 100
arm7_9 dcc_downloads enable
sleep 10
flash write_image erase $IMGFILE
reset run
sleep 10
}
====== end openocd script ======
Running this with
openocd -f openocd/openocd.cfg -f openocd/olimex-arm-usb-ocd.cfg -f
openocd/openocd-sam7s256.cfg -c "mt_flash_bin glow_flash.bin"
I get:
===== begin openocd output =====
Warn : use 'sam7se256.cpu' as target identifier, not '0'
Unknown command: mww 0xfffffd44 0x00008000
====== end openocd output ======
What am I missing there?
Everything was tested with openocd-svn2790.
Is there any documentation or any examples on this?
http://openfacts.berlios.de/index-en.phtml?title=OpenOCD_scripts seems
to be for the old config-format, and
http://openocd.berlios.de/doc/pdf/openocd.pdf seems to contain only a
tcl language tutorial, but no usable examples (same for the source).
