JLink is IAR J-Link-ARM version 6.0. At first when I run OpenOCD in terminal it gave erro messgae like:

and I use J-link commander to get the info about the jlink. What i got is :

I m totally new to OpenOCD and Jlink. Looking for help. Thanks very much.

Anyone have any info on this? I really wanted to use linux for development and it seems like there is no way with the current state of this driver.

Hi All,

I’m pretty time constrained, but will attempt to submit my fix to openOCD. My problem was that I was working on a mini2440 board which has only a 10 pin JTAG connector. Conveniently, they left off the RTCK signal (Pin 11 on the 20 pin connector) which is used for adaptive clocking. I have gone into jlink.c into the jlink_init function and wrote the code to see if adaptive clocking was working (which it won’t on a 10 pin). If it fails, then I manually set the speed to 1/2 Max. In the event that I do not get the time to check in the code to openOCD, I post the necessary code here. I modified jlink_init() and jlink_speed(), and jlink_get_speeds() is an entirely new function.
