Hello,

thanks for great peace of software!

Earlier this year I successfully used OpenOCD for programing external

flash on my LPC2292 board. Flash is TE28F320C3 from INTEL.

Now, I am back to ARM again, and when I install last (SVN88RC2)

version of OpenOCD, and try to program my board I constantly getting

this message (OpenOCD window):

```auto
C:\Program Files\openocd-2006re82\bin>openocd-pp -f arm7_wig.cfg
Info: openocd.c:82 main(): Open On-Chip Debugger (2006-08-01 12:00 CEST)
Warning: arm7_9_common.c:675 arm7_9_assert_reset(): srst resets test logic, too
Info: server.c:67 add_connection(): accepted 'telnet' connection from 0

Error: arm7_9_common.c:1910 arm7_9_write_memory(): memory write caused data abort

```

and commands that I sends are:

```auto
Open On-Chip Debugger
> flash probe 0
flash 'lpc2000' found at 0x00000000
> flash probe 1
flash 'cfi' found at 0x80000000
> flash protect 1 0 40 off
> flash erase 1 0 40
> flash write 1 linux.bin 0x8000
flash program error
wrote file linux.bin to flash bank 1 at offset 0x00008000 in 29s 218750us
>

```

I tried on windows and on linux, I get same error on both platform,

with two diferent LPC2292 based boards.

Sometimes, some of location at 0x80008000 and above a successfully

written, sometimes there are no data in flash… everything is

still erased.

please can you help me to resolve this:

this is my config file:

```auto
#daemon configuration
telnet_port 4444
gdb_port 3333

#interface
interface parport
parport_port 0x9800
parport_cable wiggler
jtag_speed 7
#use combined on interfaces or targets that can't set TRST/SRST separately
reset_config trst_and_srst srst_pulls_trst

#jtag scan chain
#format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 4 0x1 0xf 0xe

#target configuration

```

and this dump from OpenOCD window when I start it with -d

switch.
