JLink error "Failed to power up DAP" after loading the soft device

John

Hello,

I am working on a custom development board that is using the nRF52840. After programming the nRF52840 on the board with Soft Device s140_nrf52_7.0.1_softdevice.hex from the NRF5x SDK 16.0.0, I can no longer connect to the chip using a JLink Ultra or a PCA10056 dev board as a pass through debugger. When I attempt to get back to square one using "nrfjprog --recover --log", it errors out with a "Failed to power up DAP" error. I will attach the full log to this question. I had the HW guys replace the nRF52, and the same thing happened. Which leads me to think something outside the chip may be contributing to this problem, but I do not know what it could be. I have 4 other instances of the same custom development board and they work fine. I can program the soft device with nRFConnect, and then our application with IAR and all is well.

Any ideas on further debugging or cause of the problem? These boards are in rather short supply for us right now so if we could get this one working it would be a great help.

Thanks in advance,

John

    I get the same problem today on my NRF52832xxAA. After programming  the board,  which I have used for a month, I can not connect the chip anymore. I try J-Flash, nrfGo, and nrfjpro, none of them work. I think I will replace the chip. I do not use soft device, and just use the chip as an RFMCU. I have programmed it many time when i am coding and debugging. But it can not be connected today.

    When I use J-Flash to connect, the following message will appear:

    Connecting ...
    - Connecting via USB to probe/ programmer device 0
    - Probe/ Programmer firmware: J-Link V11 compiled Aug 14 2019 16:21:09
    - Device "NRF52832_XXAA" selected.
    - Target interface speed: 1000 kHz (Fixed)
    - VTarget = 3.309V
    - InitTarget() start
    - InitTarget() end
    - Found SW-DP with ID 0x2BA01477
    - Failed to power up DAP
    - InitTarget() start
    - InitTarget() end
    - Found SW-DP with ID 0x2BA01477
    - Failed to power up DAP
    - ERROR: Failed to connect.
    Could not establish a connection to target.

    When Using J-link command line, I get:

    Connecting to target via SWD
    InitTarget() start
    InitTarget() end
    Found SW-DP with ID 0x2BA01477
    Failed to power up DAP
    InitTarget() start
    InitTarget() end
    Found SW-DP with ID 0x2BA01477
    Failed to power up DAP
    InitTarget() start
    InitTarget() end
    Found SW-DP with ID 0x2BA01477
    Failed to power up DAP
    InitTarget() start
    InitTarget() end
    Found SW-DP with ID 0x2BA01477
    Failed to power up DAP
    Cannot connect to target.

    I think is the same bug of the chip.

    Can any body save my brick NRF52832 ??

    Thanks.
