openocd flashing memory of ATSAM7X256 failure

rain · November 27, 2006, 6:06pm

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

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.

Hi,

Have you installed the parallel port driver before you run the OpenOCD?

and set your parapllel port mode to be EPP?

Yes i installed the parallel port driver:

\ARM_TOOLCHAIN\openocd-2006re115\driver\parport>status_giveio.bat

status of giveio:
Type:           [0x01] Kernel driver.
Start Type:     [0x02] Automatic
Error Control:  [0x01] NORMAL: Display a message box.
Binary path:    \??\C:\WINDOWS\giveio.sys
Load order grp:
Dependencies:
Start Name:
ok.

I’m not sure if my paraport is working in EPP mode? How can i check this and where can i configure it to EPP?

Thank’s a lot,

Hi,

Enter CMOS setup and change the parallel port mode.

You should enter setup mode by pressing the delete key when Windows is booting up, and then select Integrated Peripherals, and then chose IO Device Configuration [Press Enter], and press enter key. Now you will find the Parallel Port Mode item and you can change its value. Do remember to save it before you quit.

By the way, my OS is windowXP.

Please also refer to Jim’s tutorial on eclipse “arm cross compiler with eclipse (version 3)” on page 124.

Regards,

Kevin

Thanks a lot.

I changed my parallel port mode to ECP (because i could’nt select EPP).

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:

Flash Programming Finished.

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)

Thank’s a lot

The best way to learn the correct commands is to run interactively in a telnet session.

After starting openocd open a telnet session

telnet localhost 4444

Now use the command reference on the openocd wiki and the help command.

Try:

flash info 0

flash protect 0 0 1 off

flash info 0

I have read the opeocd manual. I havent found any informations about the errors that are reported by openocd when i use my configfiles!!

As i described below I’m very new to openocd and the ARM controllers.

Can anybody tell me what’s wrong with my configuration files?

All kind of help is welcome.

Thank’s a lot

Thomas

Your configuration files seems OK. The error is that you have not turned off the protection bits, and the command to use is:

flash protect 0 0 1 off

This if the first two sectors 0 and 1 are protected, and the command to find out what sectors are protected is

flash info 0

I don’t know what you are exactly meaning.

flash info 0 returns the following:

Info: configuration.c:50 configuration_output_handler(): pagesize: 256, lockbits: 16 0x0007, pages in lock region: 64

Ther are 16 lockregions and the value of the lockbits field is 0x0007 so the first three lockregions are protected.

If you give the commnand

flash protect 0 0 2 off

Then the lockbits field should change to 0x0000 to indicate that no flash regions are protected. Now you can both erase and write the flash.

THANK’s a lot

now i’m able to flash the controller. Thank you guys for your patience.

But i’m not sure what all this commands are for. Maybe i should read the openocd doku once again…

Anyhow - thanks now it works.

Greetings from Vienna
