Error while flashing custom board with nrf9160 SiP using nrf5340DK

nano2

Hello,

I am trying to flash the Serial LTE modem on the nrf9160 on a custom board using the nrf5340DK and the nrf Connect Programmer. I am using the P20 port on the DK and have made the connections as shown here:

I am powering the custom board from an external source at 3.3V. The VDD_nRF´ is not connected to the custom board.

However I am getting the following error:

Recovering Application core
Failed to recovering application core core. Error: [object Object], message: Batch task recover failed, [jlink] JLINKARM_DLL_ERROR
Error: Failed with exit code 1. One or more batch tasks failed: - [jlink] JLINKARM_DLL_ERROR, code: Nrfjlink. Message: Batch task recover failed, [jlink] JLINKARM_DLL_ERROR.
Any idea on what could be the problem?

    This problem may be caused by the debug interface or nRF5340DK-custom board connection. Here are some ways to fix this:

    • Check Connections: Verify the nRF5340DK-custom board connections. Check the wiring and debug interface connection.
    • Double-check your custom board's power supply. It must be stable and provide 3.3V.
    • Check that the nRF Connect Programmer is configured for the nRF5340DK and that the P20 port is selected.
    • Hardware Debugging: Connect a hardware debugger like J-Link to your custom board's nRF9160 SiP for debugging and flashing.
    • Update Software: Use the latest nRF Connect Programmer and nRF5340DK firmware.
