I would have expected you to use configure interface first..


./openocd -f target/interface/jtagkey.cfg -f target/target/mx31.cfg

I have noticed that the iMX31 is *VERY* sensitive on the precise
implementation of the JTAG interface.

It didn't work w/the parport when we tried it.

On our ZY1000 reset halt works though(which uses OpenOCD):

I'm not convinced that the iMX31 will work without RCLK....
