    • j-Link Commander fails to read system register on i.mx6

      New

      Hello,


      I have a i.mx6 controller (MCIMX6D6A), which crashes at some point. After the creash happens, I want to connect to on it and read some system regs (MPCore to get exception or other fault behavior)
      Jlink connects, i can read the CPU register and RAM address space. However when I read hardware regs, it fails

      Source Code

      1. J-Link>mem 0x02160000 4
      2. Could not read memory
      I'm using J-Link Commander V6.32g with a J-Link hardware version 8.0

      Regards,
      John

      Hello John,

      Thank you for your inquiry.
      The J-Link V8 does not support Cortex-A9 debugging. More information can be found here: wiki.segger.com/Software_and_H…J-Link_PLUS.2C_J-Link_EDU
      So if connect is working then only by chance as it is not intended.

      We suggest making use of our trade-in program to get a current J-Link model: segger.com/purchase/trade-in-program/

      Best regards,
      Nino

      Hello Nino,

      Sorry for the late reply, E-Mail notifcations wasn't set.
      I borrowed a J-Link base version 10.1 from a colleague and repeated my steps.

      I got the same result.

      Am I doing something wrong? Are the Registers mapped to a different address, do I have to run some script or do I only get the system address space when I'm in a debugging eviroment?

      Regards,
      John
