Thread Summary

                The user encountered a 0x80048020 error in CCES 3.0.2.0 when trying to connect to the ADSP-21569 on EV-21569-SOM REV B and EV-SOMCRR-EZKIT REV D, even after reinstallation and trying a different computer. The solution involved using DebugAgentFlashProgrammer.exe to reflash the firmware of the debug agent, which was previously showing version 0.0.0.0. The issue was resolved after reflashing the firmware.

While debugging an application for adsp-21569 on EV-21569-SOM REV B sitting on EV-SOMCRR-EZKIT REV D using cces 3.0.2.0, it crashed.
Further attempts to debug, results in this message:


Error in launch sequence
[TpsdkServer] Failed to connect to processor.


Error: 0x80048020
Error Description: Selected emulator not detected


Since the setup worked before, it is not related to hardware or power.
I have re-installed cces and tried to run the SPDIF_ASRC_DAC_AudioPassthrough_21569 example but the error is the same.
I have also tried to connect from a different computer that used to work with it, also changed the usb-cable, but again receive the same error


please advise on how to bring this up running again.


Thank you

    Hi,
    

    The 0x80048020 error indicates a problem starting up/communicating with the emulator.
    

    Can you please check again by re-installing the driver manually? The drivers are found in the "Emu_Drivers" directory:
    <installation drive>:\analog\cces\3.0.2\Setup\Emu_Drivers
    

    Please refer "Installing drivers manually" in Emulator and Evaluation Hardware Troubleshooting Guide
    www.analog.com/.../EE356.pdf
    

    Also, Could you please try to replace the attached "libusb-1.0.dll" in the below directory. Before replacing take a backup copy of the original "libusb-1.0.dll" file that is already available in the directory and drop the new one and let us know the result of emulator connectivity.
    <installation drive>:\analog\cces\3.0.2\System
    

    If you are still facing the same issue, In order to accurately determine whether your emulator is faulty or not, can you please answer the following questions -
    

    1. Please share with us the screenshot results of ICE Test utility. ICE Test utility can be used to test for faulty JTAG connections, as well as testing your hardware configuration.
    2. If possible, can you try with different emulator(ICE-1000/ICE-2000) which operates correctly with the same target board and PC.
    3. If you have access to any other SOM/carrier board, could you please replace each other.
    4. Please refer "Jumper and Switch Settings" in the below system evaluation manuals and ensure the jumper and switch settings are set correctly in the EV-21569-SOM and EV-SOMCRR-EZKIT boards:
            https://www.analog.com/media/en/evaluation-boards-kits/evaluation-board/ev-21569-som-manual.pdf
    

            https://www.analog.com/media/en/technical-documentation/user-guides/ev-somcrr-ezkit-manual.pdf
    

    5. Try connecting the debug agent session by referring the switch settings in the above linked SOM manual and see the result.
    6. Please let us know whether you have purchased the board directly from Analog Devices or from distributor.
    

    Waiting for your reply.

    Santhakumari.V
