  • [SOLVED] J-LINK COM Port on Nordic PCA10040 Eval board - Connection Error

    I have a Nordic PCA10040 (dev kit for the NRF53832) which has an integrated J-LINK. When I connect to the PC there is also a JLINK CDC UART Port. It appears that the device has enumerated correctly.

    When I try to connect to the port via putty I get an error that I cannot connect (picture attached).

    I was able to connect to this board via Segger Embedded Studio, load code, debug, etc.

    I have also tried to connect to the com port via a Python Script provide by nordic which give as "permission denied" error when I attempt to connect.

    I tried:

    Testarting the machine
    Cycling the USB cable
    Reinstalling the CDC driver.

    Any ideas of how to fix the problem?

  • Hello,

    Thank you for your inquiry.
    We are not aware of any issues with the J-Link OB and VCOM on this particular eval board.
    Our recommendation is to contact Nordic Semi Support in that regard as they implemented the eval board hardware.

    Best regards,
    Nino
