Device Specific Handling
Connect
- During target connection, the security protection level is verified. If the device is configured with protection level low (NVMC_OBSTAT0_EFT.SPC), the user is prompted to unsecure the device before proceeding.
- A successful connection is only possible to an unsecured device.
Reset
- The device uses normal Cortex-M reset, no special handling necessary, like described here.
Attach
Attach is a debugging feature which exclusively applies to J-Link and J-Trace and does not apply to Flasher.
- Attach is supported / desired
