ADuCM355 evaluation board flash locked and no longer downloading to device

Hi there, 

I have an EVAL-ADuCM355QSPZ board that I've succesfully run a number of examples, specifically the M355_Ramp example for cyclovoltammetry as per the user guide.

I then began to set up a very basic hello world program of my own setting up the project space. It builds fine but does not flsah correctly. I have since gone back to the example that was previously working and it is also no longer flashing, see errors below: 

After checking out this forum and surfing the internet I have used J-Link Commander to check that the J-TAG connection is working properly, which it is. It seems that the flash is locked. I can't unlock it with 'unlock Kinetis' and erase wont work either. 
I have also tried to debug without downloading and there is a different warning see image below: 

From what I understand this is due to locked flash.... 

Hope someone has an answer for me! 


Thanks in advance, 

David

  • HI David,

    The best approach for setting up a new project space is to copy and paste an existing project space and just change the title. Check out this link which has instructions on how to do it.

    To recover the ADuCM355 you need to enter boot mode:

    1. Hold down button S3 and then toggle S1

    2. Release S3. 

    3. In IAR go to Project->Download->Erase Memory

    You should then be able to download and run a working project.
