Secured & Mass Erase Disabled Kinetis K60N512 Device

10,054 Views

Hi

I am working on TWR-K60N512 board. It was working fine some days ago but due to growing size of code,

Flash Configuration Filed (0x400 to 0x40C) of Program Flash Area has been updated accidentally.

Now I am unable to connect to the board and load the program in Program Flash.

When I try to connect using JLINK (JLink.exe), Following message is displayed.

Unsecure Command of JLINK

I have also tried to check unsecure command but JLINK Commander V4.42b does not support it for K60N512

****************************

CodeBench with JLINK

****************************

When connecting K60N512 using CodeBench & JLINK, following error message is displayed.

arm-none-eabi-sprite: J-Link error: Secured Kinetis device detected but mass erase is disabled.

No APB-AP found.

arm-none-eabi-sprite: error: Couldn't find a J-Link device

**********************

Using CodeWarrior

**********************

When trying to connect the K60N512 board using CodeWarrior and OSBDM/OSJTAG,

a pop up message is displayed (twice) saying

"Device is secure, Mass erase is

disabled. Try to unsecure

anyways?"

If I say yes, then another popup message is displayed saying

"An error occurred while connecting to the interface hardware or target specified in launch configuration dialog. ......"

I also tried by enabling the following option

"Always Mass Erase on Connect"

but no success.

*****************

Is there any solution (Hardware/Software) to

- Unsecure the device

- Mass erase should be enabled.

Hi,

Try the following:

1. drop the erase_all_pin.jlk in the “Program Files\IAR Systems\Embedded Workbench 6.0\arm\bin” directory

2. Power off the board

3. Assert the reset pin and hold it asserted for the remainder of the process.

4. Power on the board

5. go to a command window navigate to the “Program Files\IAR Systems\Embedded Workbench 6.0 Evaluation\arm\bin” directory and execute the script by typing “jlink.exe erase_all_pin.jlk” .

6. Release the reset pin

7. Try to connect with debugger

Luis

Yes, I tried

1. CodeBench with JLINK using JTAG connector

2. CodeWarrior with OSJTAG

Hello,

I have recovered some customer boards with the procedure explained. With the script I attached, JLINK and JLink commander, last time with V4.50I from segger.com . To mantain the reset in the procedure was the key.

Best Regards,

Luis

How I executed the Script?

1. Power Off the board

2. Press the Reset Button [SW3]

3. Power ON the board

4. Execute the script [jlink.exe erase_all_pin.jlk]

5. Release the Reset Button [SW3]

Now connect the board

1. using CodeBench, JLINK with the help of connector

2. using CodeWarrior, OSJTAG/OSBDM

Am I missed some settings/configurations.

Here is the output of script

Hello,

Try to power the board from TWR-ELV USB connector. Did you receive a pop up window from commander about that you device is secured and if you want a mass erase?

"Try to power the board from TWR-ELV USB connector"

Yes

"Did you receive a pop up window from commander about that you device is secured and if you want a mass erase?"

1. When I use CodeBench + JLINK, no pop up window is displayed.

2. When I use CodeWarrior + OSJTAG, Pop up window is displayed by stating a message

"Device is secure, Mass erase is disabled. Try to unsecure anyways?"

If I say yes, then another popup message is displayed saying

"An error occurred while connecting to the interface hardware or target specified in launch configuration dialog. ......"

After retrying, downloading is failed.

Hello,

Using the Segger software and the script, you should receive a pop-up screen about that Device is secured. Did you get it? Don't forget that you can block forever the device if you wrote in the config registers a bad value. With segger software and script I have recovered all the devices that were not fully locked.

Thanks for your valuable suggestions. I think the board has been locked & secured permanently and can not be programed now. It is also verified by Board Vendor.

Hello,

I solved with command "Jlink unlock Kinetis" from ...\IAR Systems\Embedded Workbench 6.5\arm\bin
