Dear Renesas Support Team,
I am currently working with the Renesas RA6M1 microcontroller and have encountered an issue related to the ID code authentication. Unfortunately,
I am unable to establish a connection with the device using my J-Link debugger due to an incorrect or unknown ID code. Attempts to use the default ID code (FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF) have also failed, and I am unable to proceed with programming or erasing the chip.
Below are the details of the issue:
Microcontroller: RA6M1Toolchain: J-Link debugger (J-Flash V7.22)Error Message: "SC32 (connect): Failed to authenticate debugger via IDCODE. Incorrect IDCODE? Failed to connect. Could not establish a connection to target."Actions Taken:Attempted to connect using the default ID code (FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF).I would appreciate your guidance on the following:
Is there an alternative method to reset or erase the chip if the ID code is unknown?Could you confirm if entering boot mode on the RA6M1 would allow me to bypass the ID code and perform a full chip erase?Are there additional recovery steps or tools available for this situation?Thank you for your time and support. Please let me know if you require further details or logs regarding the issue.
Looking forward to your assistance.
