When I try to burn flash on a ADuC7021 using the ADuC702x.cfg I get a a
crash. (traceback attached)
in aduc7021.cfg if I comment out the following line it works
$_TARGETNAME configure -work-area-phys 0x10000 -work-area-size 0x2000
it just takes a LONG time - of course)
The lines below the HALT can be commented out with no effect.
I included them here because they were active during this traceback

I then erase flash and issue:
