Startup Troubles on Dev Kit

[SteveHx]

I was able one time to power up the nRF9160 dev kit and see it connect to the cellular network and to nRF Cloud. Since then, it will only blink LED3, which indicates that it can't connect. I would like to re-flash the firmware, but I'm totally lost in all the circular links in the documentation. I have used the nRF52832 dev kit extensively so I'm quite familiar with the process, but it appears the nRF9160 dev kti adds several more layers of complexity. I would like to be able to load a simple "hello world" application, and then build on that with my application source code. Please guide me to some concise documentation.

I understand what it's asking for. What I need to know is where to get the GNU ARM toolchain - I don't think I have that installed. In any case, I always allow published installers to install to their default directories, because I've found way too many whose developers didn't bother to check what happens if the user uses a different directory - it often breaks the product. Where should I get the GNU ARM toolchain, in a version compatible with this toolchain?

[Didrik Rokhaug]

Sorry, I misunderstood what you were asking for. In the Getting Started Assistant there are two links at the bottom of step 1 "Install the toolchain":

Windows 32-bit Installer (Signed for Windows 7 and later)

Windows 32-bit Installer (Unsigned)

We recommend to install the toolchain into the c:\gnuarmemb folder

It still looks like the "GNU ARM Embedded Toolchain Directory" option is wrong. Can you confirm that the content of the folder you have provided in that option contains the same as:

Also, when building an application which uses the modem on the nRF91, you must build the application as non-secure. The board name should be "nrf9160_pca10090ns", notice the "ns" at the end.

I cannot find any directory that looks like your picture. I presume we're talking about where I unzipped EmbeddedStudio_ARM_Nordic_v420a_win_x64.zip. Per your suggestion, I unzipped it directly to C:\ (which seems to me like a bad idea to begin with, but you're the expert). I have tried setting the path in SES to both C:\ and c:\arm_segger_embedded_studio_v420a_win_x64_nordic, same result.

[Didrik Rokhaug]

I am not talking about the unzipped SES folder, but the ARM Embedded toolchain (arm-none-eabi-*). You should have installed it as the last step on page 1 of the Getting Started Assistant ("Install the toolchain"). If you did not, here are the links:

• Windows 32-bit Installer (Signed for Windows 7 and later)

• Windows 32-bit Installer (Unsigned)

The default install folder from the installer is: C:\Program Files (x86)\GNU Tools Arm Embedded\7 2018-q2-update.

The install folder for the ARM Embedded toolchain should have the same contents the picture from my last comment.

[SteveHx]

The ....2018-q2-update directory was already there, and looks as you showed except for the uninstaller. I have reinstalled that and now it looks just like yours.

When I open emStudio, I always get the dialog box shown below. I've tried answering both yes and no different times, and I still always get this. I suspect it indicates I'm still missing some critical step in this absurdly over-complicated setup process:

I have stopped at its first ocurrance this time, pending your answer as to the next step.

[Didrik Rokhaug]

That path is not in c:\arm_segger_embedded_studio_v420a_win_x64_nordic, and I cannot find the mentioned package in my folder.

Do you have another SES version installed?

If so, make sure that you are using the correct version (run the executable emStudio in the c:\arm_segger_embedded_studio_v420a_win_x64_nordic\bin folder).

If that does not help, you might be able to solve the issue by running the other SES version and fixing the problem there, or by uninstalling the other SES version.

[SteveHx]

We are going in circles. I am right back where I was two weeks ago.

I have confirmed only one emStudio installed, via Windows Control Panel Programs and Features. I am running exactly that emStudio, in the recommended installation directory. Every time I open it, I get that same dialog box shown two messages above. Whether I answer yes or no, I then get the request to activate. I activate tho Nordic license (corrupting my legal company name because the box won't accept a comma in the company name), and the next time I open emStudio, I'm right back at the beginning of this paragraph.

My client is getting impatient to see some results. So am I.

[Didrik Rokhaug]

I am still working on a solution to the outdated package problem. In the meantime, if you press "yes to all", are you then able to open and build a sample project?

That should make the license "stick", and there does not seem to be anything wrong with the hex files produced by SES after pressing "yes to all", so you would at least be able to start development while you are waiting for a permanent solution on the outdated package.

[SteveHx]

Still doesn't work. I'm working with David Martin, and we're still getting this:

[SteveHx]

Another possible clue: I get this error box:

If I navigate to that specific file and dblclick, another instance of SES opens, and immediately gives me the same box again.

[Didrik Rokhaug]

It still looks like the "GNU ARM Embedded Toolchain Directory" is wrong. I recreated your issue on a Windows 10 VM, by setting it to the path of SES, instead of the path of the ARM embedded toolchain. See pictures:

If you change the "GNU ARM Embedded Toolchain Directory" option to the folder where you installed the ARM Embedded toolchain, then the error goes away, and you should be able to load and build the project. If you did not change the install directory in the ARM Embedded toolchain installer, the correct path should be C:\Program Files (x86)\GNU Tools Arm Embedded\7 2018-q2-update. I have attached pictures of the correct setup (on my VM), along with the content of the folder you should point to (when setting the path, only folders will be displayed, so you will not see the uninstaller):

If you still cannot get it to work, please send pictures of the SES options window, and the folder pointed to by the "GNU ARM Embedded Toolchain Directory" option.

Edit: Also, when opening a project, make sure that the "Clean Build Directory" checkbox is checked, to avoid risking using old settings.
