I’m not able to configure my test card (AT91SAM7-STK) with OpenOCD (0.1.0), JtagKey (Amontec) and IAR (GDB server). Here is my configuration file :

#interface
interface ft2232
ft2232_device_desc "Amontec JTAGkey A"
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0xcff8
jtag_speed 0

if { [info exists CHIPNAME] } {	
   set  _CHIPNAME $CHIPNAME    
} else {	 
   set  _CHIPNAME sam7L128
}

if { [info exists ENDIAN] } {	
   set  _ENDIAN $ENDIAN    
} else {	 
   set  _ENDIAN little
}

if { [info exists CPUTAPID ] } {
   set _CPUTAPID $CPUTAPID
} else {
  # force an error till we get a good number
#   set _CPUTAPID 0x05B1E03F
   set _CPUTAPID 0x3F0F0F0F
}

#use combined on interfaces or targets that can't set TRST/SRST separately

I connect to my card but I’m not able to write to flash either with a telnet connection (flash write_bank kill OpenOCD), or via IAR IDE. Here are message from IAR IDE :

Is there something wrong with my configuration?

Thanks a lot.

I found my errors after a lot of readings, so I will post modifications for those who can be interested. First of all there was an error in my OpenOCD configuration file in the mapping and size of flash memory. I modified it with :

$_TARGETNAME configure -work-area-virt 0 -work-area-phys 0x00100000 -work-area-size 0x20000 -work-area-backup 0

Then I discovered a problem with my configuration of IAR flash loader. I need to change the configuration of the Base flash loader to 0x100000.

With those two modifications and some other configurations with SAM-BA, I am now able to debug my program.
