I tried replicating your problem on a fresh Ubuntu (16.04) install, but I'm able to connect to the board just fine using JLinkExe. Is your board mounting the JLINK drag-and-drop station (/media/ubuntu/JLINK/) when you connect it to your computer? If so, can you put the board into bootloader mode (hold reset while powering the board), and try to copy the J-Link Interface MCU Firmware to the device, now mounted as BOOTLOADER?

In other machine with Ubuntu Xenial I installed JLinkExe and the first time I executed so, JLinkExe , the second time I run JLink with -device nRF52 but I get the same error:

I think that the FIRST time that you run JLinkExe, you should not use the "-device nRF52" option. JLink updates the SEGGER firmware on the board when you run it the first time, and that is when the device ID is created. Starting with the second time you run JLink, you can (and should) use "-device nRF52".

Thanks Ladasky,

I have installed JLinkExe but I cann't to connect to the board, I get this error:

javi@PC:~/Development/Nordic/nRF5x-Command-Line-Tools_9_0_0_Linux-x86_64/nrfjprog$ JLinkExe -device nRF52

JLinkExe -device nRF52

Connecting to J-Link via USB...FAILED: Can not connect to J-Link via USB.

I'm going to try add a dev rule in my Linux installationto see if it solves the problem.

PD: I have the PCA10040 connected to PC via USB and Power ON

Thanks Jørgen,

I have used nrfjprog --family nrf52 --eraseall , but I get this error:

javi@PC:~/Development/Nordic/nRF5x-Command-Line-Tools_9_0_0_Linux-x86_64/nrfjprog$ ./nrfjprog --family nrf52 --eraseall
ERROR: There is no debugger connected to the PC.

I'm going to try add a dev rule in my Linux installationto see if it solves the problem.

Javier,

I have had similar problems when I try to use the S132 SoftDevice. Sometimes it seems to be necessary to completely erase the board, other times not. I use JLinkExe on my Linux system to flash and erase the nRF52. Here are a few links where I describe my problem and the solutions that have worked for me, they may help you:

You can use nrfjprog from nRF5x-Command-Line-Tools, which is available for linux, to erase the board. Use the command: nrfjprog --family nrf52 --eraseall

Hi Jørgen,

I haven't tried erasing the board. I'm on it. But I have other problem, I haven't ARM Keil, I haven't Windows, only Ubuntu Xenial or Fedora 25 Workstation.

How I can erase de board without Keil?

Thanks and greetings

Hi, how are you flashing your board? Have you tried erasing the board before flashing? Are you able to flash the precompiled hex-files?
