  • [SOLVED] J-Link Commander Renesas RX Authentication Key

    Hey Everyone,

    I have some Renesas RX micros that have their read and write access protected by an ID code. I can connect to the RX micros, but the authentication key is rejected by the CPU.

    C Source Code

    1. Device "RX" selected.
    2. Connecting to target via FINE
    3. Cannot connect to target.
    4. J-Link>power on
    5. J-Link>connect
    6. Device "RX" selected.
    7. Connecting to target via FINE
    8. FINE: Found Renesas device
    9. Found Renesas RX210 device (MCU_DR: 0xD011)
    10. Starting debugger authentication...
    11. ****** Error: Debugger authentication failed. Authentication key rejected by CPU
    12. Cannot connect to target.
    Display All


    How do I pass my authentication key to J-Link Commander? I've looked through the manual and been unable to find the solution.
