  • [SOLVED] j-link do not erase or program device STM32F103 in long JTAG chain

    Greetings!

    I have a device with long JTAG chain (one STM32f103, then two different PLD`s, then other STM32F103).
    I need to program a last one STM32. I used a ULINK2 for this and are trying to move forward to J-Link (Base version).
    You can have a look at the chain in attachments.

    I`m trying to program the controller with KEIL mVision 5.24 + J-Link HW 10.10 and dll 6.30b.

    mVision prints Build Output like this:

    Target info:
    ------------
    Device: STM32F103VE
    VTarget = 3.349V
    State of Pins:
    TCK: 1, TDI: 0, TDO: 1, TMS: 0, TRES: 1, TRST: 1
    Hardware-Breakpoints: 6
    Software-Breakpoints: 8192
    Watchpoints: 4
    JTAG speed: 1000 kHz

    Erase Done.
    Programming Failed!
    Error: Flash Download failed - "Cortex-M3"

    But actually it didn`t erase flash. Algorithm inside still working properly.

    A few more information about JTAG chain - yes, i have pull-ups and pull-downs connected. This device previously worked fine with ULINK2. Yes, RESET pin is connected to RESET chain of the device.

    Do you have any advice for me? Could it be connected with "JLink Warning: CPU could not be halted"?

  • Hello Vsevolod,

    Thank you for your inquiry.
    Such an issue is not known to us.
    The J-Link Commander screen shot you provided shows only the connection to the first STM32 device.
    Could you make a screen shot of the connection to the second STM32 device?
    For this you need to specify the Device position in the JTAG chain.
    In this case IRPre would be 25 and DRPre would be 4.

    When using uVision to flash the second STM32 device could you provide a J-Link log file of that session?

    Best regards,
    Nino

  • Hello,

    Thank you for providing the information.
    A general connect to the device works with J-Link Commander.
    If you are looking into only programming your devices you can keep using J-Link Commander and use command loadfile and your build output from uVision.
    More information can be found in the J-Link user manual.

    uVision itself does not know exactly which device you want to connect to and randomly selects one of the available JTAG devices which leads to the reported error.
    To counter this you need to tell J-Link exactly which JTAG device you want to connect to.
    First you need to specify a JlinkScript: wiki.segger.com/Manual_setup_of_JTAG_chain
    To use the script with uVision follow the following guide: wiki.segger.com/Keil_MDK#Using_J-Link_Script_Files

    After that you should be able to flash the other STM32 device as well.

    Best regards,
    Nino

  • Ok, i`ve done all you wrote.
    Let`s have a little check, my JLinkSettings script is in attachments.
    But there is still a mistake (actually another one). I attached a log file with my programming.

    UPDATE

    Sorry, seems to be a mistake in previous JLinkSettings. The actual one is here:

    JLINK_SYS_Report("J-Link script file: Manually configuring JTAG chain");
    JLINK_JTAG_SetDeviceId(0, 0x3BA00477); // IRLen: 4
    JLINK_JTAG_SetDeviceId(1, 0x16410041); // IRLen: 5
    JLINK_JTAG_SetDeviceId(2, 0x1E9041CF); // IRLen: 8
    JLINK_JTAG_SetDeviceId(3, 0x1BA541CF); // IRLen: 8
    JLINK_JTAG_SetDeviceId(4, 0x3BA00477); // IRLen: 4 => CoreSight DAP (This is the one we want to communicate with)
    JLINK_JTAG_SetDeviceId(5, 0x06414041); // IRLen: 5
    //
    // Pre-select CoreSight DAP to be the one J-Link shall communicate with, for this session
    //
    JLINK_JTAG_IRPre = 25; // Sum of IRLen of all JTAG TAPs preceding the one we want to communicate with
    JLINK_JTAG_DRPre = 1; // Number of JTAG TAPs preceding the one we want to communicate with
    JLINK_JTAG_IRPost = 5; // Sum of IRLen of all JTAG TAPs following the one we want to communicate with
    JLINK_JTAG_DRPost = 5; // Number of JTAG TAPs following the one we want to communicate with
    JLINK_JTAG_IRLen = 4; // IRLen of device we want to communicate with

    But it changed nothing, i have a error in uVision:
    ***JLink Error: STM32: Connecting to CPU via connect under reset failed.via connect under reset failed

  • Hello,

    Your initial JLinkScript had JLINK_CPU = CORTEX_A5;. That is incorrect, make sure to remove that line.

    If you want to connect to the second STM32 then the attached script should be correct except the Cortex-A5 part:

    JLINK_JTAG_IRPre = 25; // Sum of IRLen of all JTAG TAPs preceding the one we want to communicate with
    JLINK_JTAG_DRPre = 4; // Number of JTAG TAPs preceding the one we want to communicate with
    JLINK_JTAG_IRPost = 5; // Sum of IRLen of all JTAG TAPs following the one we want to communicate with
    JLINK_JTAG_DRPost = 1; // Number of JTAG TAPs following the one we want to communicate with
    JLINK_JTAG_IRLen = 4; // IRLen of device we want to communicate with

    In your post update you seem to mix up information from the first STM32 and second one. That will not work.

    Please understand that we can't put more time into this as the J-Link communication is generally working with J-Link Commander and only uVision is trying to connect to the wrong device.
    For simple programming of devices J-Link Commander or J-Flash can be used as well.
