J-link OB cannot find nRF52811 on custom board

bardia3000

Hello, I'm working on a custom board, and I use JLink OB as programmer. Whenever I try to connect to nRF52811 on the board, this happens:

I check the connections, everything looks fine, Could It be because of the firmware of my Jlink OB?

    Hi,

    Whenever I try to connect to nRF52811 on the board

    Looking at the screenshot attached, you seem to be using a project that is configured to be used for the nRF52840.

    Please try the pca10056e project instead. For the ble_app_blinky project, see the project in the folder SDK_folder\examples\ble_peripheral\ble_app_blinky\pca10056e\s112\ses

    You might find the Developing for nRF52811 user guide useful. See this link: infocenter.nordicsemi.com/.../nrf52811_user_guide.html

    Unfortunately it is the same as before.

     Are you able to recover the device using nrfjprog ?

    nrfjprog --recover

    What voltage are you powering the nRF52811 with?

    No I can't recover the device.

    nRF52811 is powering with 1v8, by the way I checked the programmer, It can program a nrf52832 (powered with 1v8) on another board correctly!

    I also tried Segger J-Flash (and I change the programmer device): Here is the result of Log:

    Connecting ...
    - Connecting via USB to probe/ programmer device 0
    - Probe/ Programmer firmware: J-Link V9 compiled Jun 2 2222 22:22:22
    - Device "NRF52811_XXAA" selected.
    - Target interface speed: 4000 kHz (Fixed)
    - VTarget = 1.790V
    - InitTarget() start
    - InitTarget() end
    - InitTarget() start
    - InitTarget() end
    - ERROR: Failed to connect.
    Could not establish a connection to target.

    and after I changed the speed to auto mode:

    I also run "it as administrator" with J-link OB:

     

    and this is the log file:

    By the way, I checked voltage on all pins, It is a bit strange that P0.21/nRST is Low( while I used pull up resistor on it) and also I've never program it, So this GPIO shouldn't be configured as an active-low Reset!

    Is it normal for the P0.21/nRST to be Low in this situation?
