Hi all,
I would like to ask for your help. I have a problem. I use olimex board
with procesor LPC2919. I am not able to write to the flash.

use of EmbeddedICE dbgrq instead of breakpoint for target halt enabled
dcc downloads are enabled

When I put flash probe 0 for first time I get
Unknown LPC29xx derivative
unknown error when probing flash bank '#0' at 0x20000000
for second time :
flash 'lpc2900' found at 0x20000000
flash erase_sector 0 0 1
I get
*** [program] Segmentation fault
I am using Ubuntu 10.04 on virtual VMware PC. and openocd version is 0.4.0

I have no problem with flashing LPC2144,LPC2129,LPC2148
Thank you
