Ok, I got it...
SRST is RESET I guess...
Anyway I issued the following command
sudo openocd -d1 -f interface/jlink.cfg -c "transport select jtag" -c "adapter_khz 6000" -f board/imx28evk.cfg -l ~/openocd_log
and the first time I got this:

I mistyped -dl instead of -d1... Then I did the telnet connection and it worked!
Then I trid again the connection but added a new option, to save the output log of openOCD like this:
sudo openocd -d1 -f interface/jlink.cfg -c "transport select jtag" -c "adapter_khz 6000" -f board/imx28evk.cfg -l ~/openocd_log
and I got this:

I hope this is OK...
Now I'm going foe the telnet connection again...
But before I want to ask another question:
What I'm doing is just a memory dump, right? Is this anyway dangerous to the scope? Can I brick the scope?
