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 'C:\Programme\ARM_TOOLCHAIN\openocd-2006re115\bin\'at91sam7s256-wiggler- flash-program.cfg Info: openocd.c:82 main(): Open On-Chip Debugger (2006-10-12 18:00 CEST) Debug: jtag.c:1210 jtag_init(): Debug: parport.c:373 parport_init(): requesting privileges for parallel port 0x378...

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. lg 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: ------------------------------------------------------------------------ ------- 'C:\Programme\ARM_TOOLCHAIN\openocd-2006re115\bin\'at91sam7s256-wiggler- flash-program.cfg Info: openocd.c:82 main(): Open On-Chip Debugger (2006-10-12 18:00 CEST) Warning: arm7_9_common.c:683 arm7_9_assert_reset(): srst resets test logic, too Info: target.c:219 target_init_handler(): executing reset script 'c:\scriptTemp\temp.ocd' Info: configuration.c:50 configuration_output_handler(): requesting target halt...

------------------------------------------------------------------------ ---- 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
Problem solved: I forgot to erase the Lock Bits. now it works fine. cheers, Tom
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

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. florian
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. Martin Thomas

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. Jonathan
