Hi,

i have a windows 7 system with vmare and ubuntu 10.10 maverick running.
I have the j-link lite edtion connected to the Topas900 eval board from Toshiba.
I do the call "sudo openocd -f ./board/topasa900.cfg -f ./interface/jlink.cfg".
I am using local copies of the config files.
Then i get the following messages:

Any ideas why the jtag init does not work?

Thanks,

Hi,

perfect thanks a lot for the hint with an earlier firmware version.
Now i have the segger j-link lite debugger running [img]http://forum.sparkfun.com/images/smilies/icon_smile.gif[/img]

I found the older firmware versions under:

segger.com/cms/j-link-older-versions.html

I used the Version v4.10i

http://www.segger.com/cms/admin/uploads ... _V410i.zip

The problem is that i have downloaded the newest firmware version at the beginning
and so have updated to 4.22.
Using goggle i found the trick command "exec invalidateFw".
I installed v4.10i and open jlink.exe enter the above command and the older version
gets installed in the j-link lite debugger.

After that i enter vmware and opened openocd and got:
