Hi Chris,

I am a bit hazy with tcl, with respect to definition of functions and
exactly when they are executed and how exporting variables works
etc. And I have not had time to figure it all out.
The mechanism is definitely broken, but I think that the
embedded-artists_lpc2478-32.cfg script is the only one that uses
$_TARGETNAME to actually do anything. Of course any users board script
will be broken too, but like me they all probably figured they did
something wrong and worked around it.

My own workaround is to manually define $_TARGETNAME in my board script.

#seems to be needed since target file fails to export it
set _TARGETNAME lpc2478.cpu
# override version in lpc2478.cfg since this uses wrong clock
# frequency and causes flashing to be unreliable. This gets called
# during init
proc init_targets {} {
echo "Our init_targets: flash configured for 72MHz."
setup_lpc2478 72000 500
}
# seem to need this here now
init
# reset handler that can reset the memory map and clocking to a defined state
$_TARGETNAME configure -event reset-init {
my_init_pll
}
