I follow up your instructions and I get below message

Error: Invalid command argument
ETB: TAP omap4460.etb does not exist
Runtime Error: ./build/share/openocd/scripts/target/omap4460.cfg:130:
in procedure 'script'
at file "embedded:startup.tcl", line 58
at file "ti_pandaboard_es.cfg", line 3
in procedure 'etb' called at file
".//build/share/openocd/scripts/target/omap4460.cfg", line 130

should I add .chain = etb_command_handlers as well?
Meanwhile, shall we let openocd know where the base address of etm/etb is?

if so far openocd doesn't support etm/etb in cortex, do I have the pleasure
try to realize it? ^^

Appreciate your kind help,
