  • [REOPENED] Can't connect to a CC2650 using a J-Trace

    Hi, I'm trying to use a J-Trace to load code and debug a TI CC2650. I am getting a similar error message to the one listed in this thread:

    [SOLVED] CC2650 JLinkExe connection issue

    That issue was fixed with the Sep 8, 2015 release. However, the J-Trace I'm using, after updating the firmware, has firmware dated Sep 4:

    Source Code

    1. Firmware: J-Trace Cortex-M Rev.3 compiled Sep 4 2015 18:16:12
    2. Hardware version: V3.10


    Is having that firmware date expected? I have tried both using IAR and using J-Link Commander without success. Here's the error with J-Link Commander:

    Source Code

    1. Device "CC2650F128" selected.
    3. ****** Error: CC2538 (connect):Can not find ICE-Pick (IDCODE mismatch). Expected 0x0B00002F, found: 0xFFFFFFFF
    5. ****** Error: CC2538 (connect):Can not find ICE-Pick (IDCODE mismatch). Expected 0x0B00002F, found: 0xFFFFFFFF
    7. ****** Error: CC2538 (connect):Can not find ICE-Pick (IDCODE mismatch). Expected 0x0B00002F, found: 0xFFFFFFFF
    9. ****** Error: CC2538 (connect):Can not find ICE-Pick (IDCODE mismatch). Expected 0x0B00002F, found: 0xFFFFFFFF
    10. Can not connect to target.


    I tried using a coworker's I-jet in IAR, and it worked fine. Any suggestions?

  • Hi,

    Is having that firmware date expected

    Correct, Firmware: J-Trace Cortex-M Rev.3 compiled Sep 4 2015 18:16:12 is the most recent firmware for J-Trace Cortex-M Rev 3.
    The issue was located in the J-Link PC Software, not the firmware.

    Could you provide us with a J-Link logfile?
    Log output can be enabled like as follows:
    • Open a connection to J-Link, e.g start J-Link Commander
    • In J-Link Control Panel: (Click the J-Link symbol located in the notification / tray area in order to open J-Link Control panel)
    • Open the tab "Settings"
    • Next to the field "Log file" check "Override" and click "..." in order to choose a log file path.

    This is also described in UM8001 Chapter 5 "Working with J-Link and J-Trace", Section 5.7 "J-Link control panel" .

    Best regards,
    Niklas

    That's what I was wondering. Thanks.

    I tried to connect using JTAG instead of SWD in J-Link Commander, and now it worked (I think I tried before and it didn't). However, the first time after I plug the J-Trace in, it still fails to connect using IAR. After the first try, I can download code and debug. Previously, I tried over and over, and I know it wouldn't work in IAR. I don't know why it will work except for the first time now. I am fine if it doesn't work the first try, but I've attached a log in case you want to see it.

    I still have another problem. When I click "Break" in IAR, I get an error that the "CPU could not be halted" and then debugging ends. I have attached a log of when I tried.

  • Hi,


    sorry for the delay in response.
    Could you please download & install the latest version of the J-Link software & documentation pack (V5.10q) and use the integrated DLL Updater in order to update the DLL used by IAR EWARM?

    You can check the version IAR EWARM is using by taking a look at the Debug Log:

  • A coworker was doing most of the work on our project using the CC2650, so it wasn't as important that I get the J-Trace working great. However, he is no longer working on it, so I'm back to using the J-Trace and still having problems (although J-Trace works great with the ST processors I usually use it with).

    Today I have been trying, but I have not managed download code onto the chip once. I updated to the newest J-Link software pack and updated the firmware on the J-Trace, and I still can't download code. I can use an I-jet fine, so I'm reasonably sure the connection is good. A dialog asks 4 times whether it should unlock/unsecure the device, and I've tried both ways without success. Here's the IAR log:

    It also fails to connect when I try J-Link Commander. Here is a log from it:

    FailureToConnect.txt

    Any help is appreciated.

  • Hi,

    according to the Log file, SWD is selected as interface in IAR:

    C Source Code

    1. T1AA4 023:017 JLINK_TIF_Select(JLINKARM_TIF_SWD) returns 0x00 (0003ms, 0021ms total)

    Could you please select JTAG and give it a try?

    Best regards,
    Niklas

  • Unfortunately, as you can see below, that option is disabled in the settings, and I don't know why. I have tried changing a couple other settings to see if the option would get enabled, but without success. I'm using IAR 7.60.1.



    EDIT: In case you want me to try JTAG in J-Link Commander, here's a log (I tried both SWD and JTAG earlier, but only posted the SWD log):
