  • Connecting J-Link to an ARM11

    I'm trying to connect the J-Link through JFlashARM to an ARM1176. At this point I'm just trying to establish initial JTAG communication, but it does not appear to work.

    The JLinkARM.log produces the following output:

    From the log it looks like the J-Link is not able to identify the ARM11, it claims that it sees a Cortex-R4 but I'm guessing that this is just the last device in the list?
    Any help would be greatly appreciated.

  • Hi Ossian,

    for checking the initial / basic communication of J-Link + device, J-Link commander should be used.
    What about J-Link commander? Is it able to detect the device correctly?


    Best regards

  • JLink commander output

    H Alex,

    The following is the output from JLink Commander:

    It does not look like J-Link Commander is able to identify the device fully?

  • More experimentation but still no luck

    Using a simple Default.JLinkScript with CPU=arm1176jfs;

    J-Link commander produces the following output:

    Although it looks like J-Link Commander accepts the provided identification, I'm still not able to halt the cpu or query the registers?

    Calling halt (h) produces the following output:

    Any ideas what might be the issue? Any advice for what types of commands I might try in the Default.JLinkScript to get things working?
