Hmm, ok, on the command line this seems to be the difference.
Any idea what might be different doing it at (telnet) command prompt:
-- cut --
openocd -s lib/openocd/ -f interface/dummy.cfg -f target/omap3530.cfg
Open On-Chip Debugger
> targets
CmdName Type Endian AbsChainPos Name State
-- ---------- ---------- ---------- ----------- ------------- ----------
> init

omap3.cpu

-- ---------- ---------- ---------- ----------- ------------- ----------
0: omap3.cpu cortex_m3 little 0 omap3.cpu unknown

vs.
-- cut --
openocd -s lib/openocd/ -f interface/dummy.cfg -f target/omap3530.cfg

? Independent of init and target create order, both give the same
result: Failing ocd_mem2array.
