[Taron]

Hello,

Im trying to flash RAYTAC AN54L15Q-DB board but im keep getting following error:

Error: One or more batch tasks failed:
* 1050050051: [Probe] Emulator error: Failed to open connection (Generic)

FATAL ERROR: command exited with status 1: nrfutil --json device x-execute-batch --batch-path 'D:\Taron\nRFvscode\peripheral_uart_v2.8.0\build\generated_nrfutil_batch.json' --serial-number 1050050051

Thanks for help.

Hello,

I see from the screen shots which versions of "nrfutil" and "nrfutil device" you are using. Are you using nrfutil directly in power shell or terminal?

If you run "nrfutil device device-info" are you able to read from the board you are trying to program? What response do you get then?

Standard thing to check is voltage, is the board powered up as intended? Are you able to measure voltage?

Best regards

Asbjørn
