Hi,
I am using the PPK2 to evaluate the nRF5340. Neither of these devices is currently working properly, I think the underlying cause has something to do with USB that's why I created only one issue.
- PPK2
It works the first time after restarting my computer. If I then close Power Profiler and select the device again it hangs at 'Opening device with s/n EAA9B4F32C15'. After that it will not be usable. I have tried unplugging/replugging the USB, using with a powered USB hub, without a USB hub, nothing works except restarting my PC. It's identical to this issue but it never got a solution unfortunately: https://devzone.nordicsemi.com/f/nordic-q-a/76900/cant-open-power-profiler-kit-2-on-windows-pc
- nRF5340 DK
It can connect fine. When I press the 'read' button to read the memory I get:
15:04:19.393 Failed to get device memory map: async task failure for id: 1865463227 msg: JLINKARM_DLL_TIME_OUT_ERROR (Origin: "Error when running fw program.") 15:04:19.393 Error when reading device
- Using a personal laptop. Both devices work fine on this machine, no issues whatsoever. This makes me sure that it's something with my installation.
- Reinstalling. I just did a clean install of all software involved, including windows drivers. Unfortunately it made no difference.
