Error : Failed to program hex file and jlinkARM.dll writeU32 returned error -1

[Banu179917]

Our Target device is NRF52805.

Our target voltage is 1.8v.

I tried to program hex file through the command line. NRF52 tried to erase a device but it failed to erase a device and gave a jlinkARM.dll writeU32 returned error -1. I've got failed to program hex file(error:33) error through the command line.

How to resolve this issue.

Hello,

You can try to use the recover command before running the program?

nrfjprog -r

You are trying to program your external board (which is custom board with nRf52805 SoC) by nRf52DK. It is recommended to power the external board separately from the DK. The voltage on the external board must match that of the DK. When the DK is powered through the USB connector, the voltage is 3V. Is this possible to show your connection set up?
