Quick Start with nRF54L15 DK - Hello World sample verification failed

I just received a nRF54L15 DK board from Digi-Key (PCA10156 0.9.1) and I'm trying to use the Quick Start app in nRF Connect for Desktop v5.1.0.

After successfully completing the "Program" step, the "Verify" step fails:

Here's the log from nRF Connect:

I also tried to program the blinky sample app from the nRF Connect SDK Fundamentals course (lesson 1, exercise 2) and the LED does not blink.

When I first plugged the board into the USB port on my computer, the LED0 LED was flashing with whatever firmware was pre-programmed on the board, so I believe the hardware is OK. However, I'm unable to get any subsequent firmware to run on the board.

  • I have also tried running "nrfutil device recover" (which completes successfuly).

    I also was able to connect to the device in the Board Configurator. I clicked the "Load default config" and then "Write config" to make sure the default config was loaded on the board.

    After performing both of these steps, the Quick Start still fails with the same error.
