"jtag init" is just bogus, it's done automatically.
"init" means switch from configuration phase to runtime phase.
"halt" means halt the target
"reset halt" means reset and try to halt the target before it executes
first instruction.

Please see the user manual for clarifications.

If you want to just flash use this:

openocd -f yourconfig.cfg -c "program your.elf verify reset exit"
