Hi,

My system:
-------------
I've a JLink ARM version 8.0 with
I'm testing it with the JLink command line 4.25a (which is a beta but I've also tested with the 4.24b).
I've it connected to a Freescale evaluation board TWR-K60N512 which has a Freescape CPU Kinetis MK60N512VMD100
Unfortunately as everything was going well I wasn't recoding everything I was doing, but I can send you any log now.

The last working thing I was doing:
-----------------------------------------
I clicked in the JLink command line icon.
I just entered the command:
exec device = MK60N512VMD100
Then I entered the command:
loadbin image.bin 0
And everything worked properly, because the following command was able to show me the
data that was saved in the flash.
mem 0 10
Then I just tried to reset the board:
r

After the image was saved, then everything started going wrong:
-----------------------------------------------------------------------------
Executing the JLink shows this:

If I try to reset the device to start from the first instruction, everything fails in the same way:

I've seen in the forums that some related problems are solved with unlock, but unlocking and reset gives me:

During this operation a dialog appears saying that "TCK (pin 9) low, but should be high. please check target hardware".

I can do any operation any longer because it always fails with similar messages about things that I don't understand: SWD-DP, APB-AB, ROM tables...

Is it possible for me to do any operation to fix this situation. How can I mass-erase the device, or stop it after a reset?

Thank you very much in advance.

I've seen what was the problem. The Kinetis K60 has some configuration registers from 0x400 to 0x40C.
This means that it had some random values so the Kinetis was secured in a random way.

After testing a lot of methods, the only way I was able to mass-erase the device was using the CodeWarrior with
the OpenJTAG included in the board. Then I fixed my program and loaded the new program and
everything worked properly.

Definitely the "unlock Kinetis" command didn't mass-erase the device, even if no error happened in the process.
The most confusing part was the error messages were not very clear about the device being secured.
I don't know if it is technically possible to know if the device is secured and give a bit more friendly messages.

I attached the wrong image that made me impossible to mass-erase the device with JLink.
