Hi everybody!

I have troubles while programming the flash of the ATSAM7X256 and the
use of openocd for this task.

My devBoard:
http://www.olimex.com/dev/sam7-ex256.html

I use the Yagarto Toochain:
http://www.yagarto.de

furthermore i read Lynch's Tutorial "Using Open Source Tools for
AT91SAM7S Cross Development revision 2" which describes the installation
of Yagarto and the startupCode and openocd cfg files very well.

I've done following steps:

-) Powersupply for the Board from the USB port of my PC
-) I connected the Parallel Port Wiggler from Olimex to the parallel
port of my PC (Notebook with dockingstation, if this is important)


Then i used the openocd flash script from Lynch's tutorial, but the
flashing fails. Then i used the script file from
http://www2.pt.tu-clausthal.de/~alexp/arm/index.html which is adopted
for the ATSAM7X256. (Lynch tutorial is for the ATSAM7S256)

this is Lynch's openocd config file, which i'm currently using:

-------------------------------------------------------------------
#define our ports
telnet_port 4444
gdb_port 3333

#commands specific to the Amontec JTAGKey
interface parport
parport_port 0x378
parport_cable wiggler
jtag_speed 0
jtag_nsrst_delay 200
jtag_ntrst_delay 200

#reset_config <signals> [combination] [trst_type] [srst_type]
reset_config srst_only srst_pulls_trst

#jtag_device <IR length> <IR capture> <IR mask> <IDCODE instruction>
jtag_device 4 0x1 0xf 0xe

#daemon_startup <'attach'|'reset'>
daemon_startup reset

#target <type> <endianess> <reset_mode> <jtag#> [variant]
target arm7tdmi little run_and_init 0 arm7tdmi_r4
#target arm7tdmi little run_and_init 0 arm7tdmi-r4

#run_and_halt_time <target#> <time_in_ms>
run_and_halt_time 0 30

# commands below are specific to AT91sam7 Flash Programming
# ---------------------------------------------------------

#target_script specifies the flash programming script file
target_script 0 reset c:\scriptTemp\temp.ocd

#working_area <target#> <address> <size> <'backup'|'nobackup'>
working_area 0 0x40000000 0x4000 nobackup

#flash bank at91sam7 0 0 0 0 <target#>
flash bank at91sam7 0 0 0 0 0

-------------------------------------------------------------------

And this is the script for flashing the Controller, from
http://www2.pt.tu-clausthal.de/~alexp/arm/index.html :


-------------------------------------------------------------------
halt
sleep 10
mww 0xfffffd44 0x00008000
mww 0xfffffd08 0xa5000001
mww 0xfffffc20 0x00000601
sleep 10
mww 0xfffffc2c 0x00481c0e
sleep 10
mww 0xfffffc30 0x00000007
sleep 10
mww 0xffffff60 0x003c0100
arm7_9 force_hw_bkpts enable
arm7_9 dcc_downloads enable
sleep 10
poll
flash probe 0
flash erase 0 0 15
flash write 0 main.bin 0x0
reset run
sleep 10
shutdown

-------------------------------------------------------------------

And this is the output when i call openocd-pp -d -f XXX


'C:\Programme\ARM_TOOLCHAIN\openocd-2006re115\bin\'openocd-pp.exe -d -f

I get the same errors if i do not power my dev-Bord, or if i do not
connect the wiggler to the board -> very confusing!!?

What's about the jumpers on my board? -> all JTAG jumpers are not set (
TST, JTASEL ans ERASE)

When i press the reset button on the board, the olimex application boots
and shows a image on the screen. Do I have to erase this application
first before i flash my new programm into the memory?

I'm very new to openocd and the ARM controllers. Any help is welcome.
Thanks a lot.

Tom

Hi!

I changed my parallel port mode to ECP.
Then i found out that my parallelport baseaddress is at 0x3BC instead of
0x378.

I changed the config file to
parport_port 0x3BC

and now the output of openocd is:

The Errors are about the lock bits. AFAIK these lock bits must be
cleared befor the bin data can be flashed. But i dont know if my
settings in the Openocd scripts are correct.?! (see thread origin for my
config file)

ANY help is welcome!

Thank's a lot
rain

Hi Tom, I'm beginner and I try to work with at91sam7x256 and I have too
Lynch's tutorial but I don't understand what I must to do on the page 77
"Using OpenOCD to  Program the Flash memory", I understand that we must
to change some lines, but I don't know where is the file?? You can talk
about this title.

merry chistmas.

Marcelo

to have th eflash command working, you need to have the flash section in
your config file.

flash bank at91sam7 0 0 0 0 0

if this is not in your config, you will not have the flash command
available.

Well I have the same problem. But I have no idea how to delete the
lockbits to be able to access the flash. or maybe my configuration file
is wrong, i have the config from
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/openocd_intro/index.html.

I do not own a SAM7X256 board so I can not provide tested solutions
(Someone offered to send a board for tests but I have never heard from
him again after his first mail). Nevertheless I have updated my page
(siwawi...openocd_intro) with some additional information on the SAM7
from which I think it should be correct. Please re-read the page and
send feedback if it works or does not work for you.

For the sam7x, you only need to put the ERASE jumper to Start SAM-BA.
After samba have finish to program you application and ask you to lock
region, just say no. After that don't forget to write to nvwm bit 2 to
start app from flash.

The flash command to erease lock bit it

flash protect 0 0 1 off

the 1 should be reflecting the lockbit you have. if it's only samba that
is loaded, this should work. if not you should increse the 1 to X. you
can know what bit is locked by the

flash info 0

this will tell you what is the lock bit.
