- Connecting via USB to J-Link device 0 - Target interface speed: 4000 kHz (Fixed) - VTarget = 4.962V - ERROR: Kinetis (connect): Communication error while accessing MDM-AP. - ERROR: Failed to connect. Could not establish a connection to target.
My version of the jlink directory is different and does not have an erase_all_pin.jlk . I have versions:
C:\Program Files (x86)\SEGGER\JLink_V642b
and
C:\Program Files (x86)\SEGGER\JLink_V644f
Is there some other option to accomplish this task ??

Hi
Please refer attached document about how to unlock the Kinetis chip.
Customer could follow the step 6: Using Erase_all_pin.jlk script with J-Link tool.
Wish it helps.
Have a great day,
Ma Hui
