We are using MKE15Z256VLL7 microcontroller,But encounter problems.
MCU suddenly can not download the program.list is the JLink.exe`s log:
- 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.
We suspect that MCU is locked up,So we're trying to unlock it,Here is our way to unlock and screenshots.
Eager for your help, thank you!
