    Hi support,

    I have installed Analyzer2Go for evaluation purpose with a ST Nucleo-L476.
    It works great for my use case SPI and I2C with decoding working great but only when I use the “Pause” button.

    However, each time I try to capture (using the record button), the Application kinda freeze with the left panel indicating
    Capturing data / Connecting to the device…

    I have tried changing Input IO and disabling protocol analyzers with no success so far.

    Do you have any idea of what I’m doing wrong ?

    Thanks for your help

    Hi,

    This should not be related to the protocol analyzers or specific I/O. It looks like the board never responds to the asynchronous I/O request. It could happen if the board had a pre-release version of the chip that would behave differently from the final one, or if the power/wiring was unreliable.

    Does that specific board behave unreliably when trying any other firmware (e.g. STM32 samples)? Does Analyzer2Go also hang when trying to use the record mode with no input signals at all?

    Hi support,

    Thanks for your Answer.

    I had to install Analyser2go to another computer as the trial expired
    Same problem with the other computer.

    I have managed to run some sotftware on the board as it was a proto board for another project.
    In order to use it, I had installed segger jlink instead of stlink for debugging the project.
    Before using analyser2Go, I used segger tool to restore default STlink firmware.

    In order to check whether this was a problem with this version on STlink, I have plugged this board to STM32 CubeMx, upgraded to the latest version of STlink and debugged a demo software whithout trouble.

    However, trying to use it with Analyser2Go and trying to record, still failled. Also, it is not possible to try to record whithout selecting at least one input (errror message from analyser2go).

    Hereafter are the marking line by line

    Hi,

    Thanks, the board should be normally supported. Most likely, some previous firmware changes have affected some of the functions used by Analyzer2Go.

    Unfortunately, it’s hard to suggest anything more specific without being able to reproduce the problem on our side, so our best advice would be to try another board.

    Hi,

    Thanks for your answer

    Perhaps you could tell me which version of STlink firmware you are using whith this board as I try to restore it to the original state ?
    Even better if you can dump Firmware from the STLink and Firmware from the STM32L476 (of your working board) as I have other debugger in order to reflash both ?

    Thanks

    Hi,

    We have retested the STM32Nucleo-L476RG board with the latest ST-Link firmware (V2.J34.M25) and unfortunately still could not reproduce the problem. We would advise trying another board instead.
