IMHO you don't need to set "jtag newtap..." here, but you'r better add 
something like "reset_config trst_and_srst" (it both are present in your 
board and adapter). For me that works always (;

openocd -f interface/... -f target/... -c "reset_config trst_and_srst; 
adapter_khz 250;"

I guess you wanted to add them to the -c "..." above - these are 
"runtime" commands, as opposed to "config/init" commands. To use 
"runtime" commands you need to issue "init" command before them, or you 
can use them via telnet, GDB or whatever without this requirement, as 
OpenOCD does "init" automatically when it finishes with all options from 
the command line.

For example this will work:
openocd ... -c "reset_config trst_and_srst; adapter_khz 250; init; reset 
init;"

This will not work:
openocd ... -c "reset_config trst_and_srst; adapter_khz 250; reset init;"

This will work too:
openocd ... -c "reset_config trst_and_srst; adapter_khz 250;"
telnet localhost 4444
[issue "reset init" via telnet]

4\/3!!
