Error: target 'lpc2000_v2' not defined

I had to create/modify my own configuration file for lpc2138 as one didn’t come provided for this LPC in OpenOCD . Here’s a snapshot of the errors I’m getting.

Here’s a copy of the configuration file:

# Use RCLK. If RCLK is not available fall back to 500kHz.
# Depending on cabling you might be able to eek this up to 2000kHz.
jtag_rclk 500


if { [info exists CHIPNAME] } {
   set _CHIPNAME $CHIPNAME
} else {
   set _CHIPNAME lpc2138
   #set _FLASH_SIZE 0x7d000
   #set _RAM_SIZE 0x8000
   #set _VARIANT lpc2000_v2
}

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

if { [info exists CPUTAPID ] } {
   set _CPUTAPID $CPUTAPID
} else {

flash bank lpc2000 0x0 0x7d000 0 0 0 lpc2000_v2 14765 calc_checksum

Does anyone know how I can correct the errors?

I was able to fix this problem with replacing:

flash bank lpc2000 0 0 <target#> [calc_checksum]

flash bank lpc2000 0x0 0x7d000 0 0 0 lpc2000_v2 14765 calc_checksum

with the following:

set _FLASHNAME $_CHIPNAME.flash

flash bank lpc2000 0 0 <target#> [calc_checksum]

flash bank $_FLASHNAME lpc2000 0x0 0x7d000 0 0 $_TARGETNAME lpc2000_v2 14765 calc_checksum

I’m assuming the issue was that “lpc2000_v2” was being passed in as the target and basically that whole line’s parameters were pushed over by one.
