My scope had firmware 4.03.SP2 installed, and I still had some time left on the feature trial licenses so I just halted the processor while the trial time remaining screen was showing and dumped the image.

Glad to hear that worked for somebody else.  Looks like the timing of the dump really is (at least part of) the issue.  Not sure what that means for people whose trials have expired.  Maybe in that case, it might be possible to open the Options>Installed menu where it lists the trial options that have expired and try taking a dump while that dialog is displayed.  psysc0rpi0n, maybe can you try that?

Still the Error with the EmbeddedICE version and I can't halt the CPU.

I have the same problem and everything i did, couldn't figure it out.

What did you?

Edinson:
In my case it was most likely a wiring problem.
As soon as I did like shown in reply #4248 it worked without any issues.
My adapter is an Olimex ARM-USB-OCD-H and I had an additional pin (#3 at both ends) connected.
Others in this forum have used an Altera as well as far as I have read, maybe one of these may share how they did it.

Edinson:
Look at reply #4013

Daruosha:
My JTAG adaptor is Altera USB blaster and I checked the wiring several times. I just left the SRST and TRSTS and ignored them, since my Altera blaster does't have those pins. Do you think that could be the issue?
