URGENT: Device not found after nrf connect for desktop upgrade

Frikkie Badenhorst

Hi there,

This morning I updated to the latest version of the nrf connect for desktop, along with all the extensions (LTE Link Monitor, Programmer, Toolchain Manager).

However I cannot seem to detect my nrf9160 DK anymore. It does not pop up in the "Select device" on any of the apps. This is extremely frustrating. When we toggle the switch to the nrf52 however, the dk gets detected, but when toggling the switch to the nrf9160 position, we can not detect the DK, and only the J-link pops up within Programmer app:

Unfortunately I do not remember the previous versions of any of the app I had. Please advise a workaround for this ASAP!

    Hi Frikkie,

    Thanks for the information. It seems this chip is partly dead on the programming interface. I have no clue on the cause by far either.

    How do you know the chip is still running when it is powered on? Do you have programmed some firmware before?

    Do you test with some other external connection?

    VDD_IO is set to 3V now?

    Best regards,

    Charlie

    Yes I have programmed it previously with the Serial LTE Modem application and latest modem firmware and everything was working fine. 

    I know it is still working as we are able to still send and receive AT commands via the usb cable VCOM port, which is connected to the 9160. We are also able to do this via the external pins connected to the 9160 uart.

    Have tried both 3V and 1.8V
