Request for nRF54L15 JTAG Lock/Unlock Procedure

Hi Team,

We require the detailed procedure for locking and unlocking JTAG access on the nRF54L15 device. Specifically, we are looking for:

  • Steps to enable JTAG protection (lock/debug disable)
  • Procedure to recover or unlock JTAG access
  • Any prerequisites or considerations (power cycle, erase behavior, firmware impact, etc.)
  • Impact of locking on firmware updates and debugging
  • Recommended best practices for secure production configuration

This information is needed to correctly implement and validate JTAG security handling in our product.

Thanks

Haritha
