K60 locked

Hi!

Unfortunately I locked my K60-Tower because I forgot to choose the K60X_Flash.icf file in the linker options (IAR workbench).

Then I tried to unlock it with the J-Link Commander ("unlock kinetis"), but without success:

What can I do to make the tower work again? The reset LED and the red LED of the J-Link-lite-Interface light.

Thanks for your answer.

As I see, it is unpossible to revive the tower.

The J-Link Commander has commands to write to memory (e.g. w4). Maybe that could help?

I have a possible "solution" for you guys.

I had the same problem with the K60 Tower board. I called Freescale and told them the problem, 2 days later I got a new Tower. Now I am only using the RAM, not writing the flash any more. The new CodeWarrior seems to display a warning when trying to burn the flash with a file that will lock the processor. Googling this message brings up a post in this forum saying this bug will be fixed in the next revision of CodeWarrior.

Hope that helps.
