blinky isn't

[tylerca310]

How do I resolve/update:

zephyr-sdk is outdated. Found 0.16.5, but 0.16.8 is required by the SDK.

 python is outdated. Found 3.9.13, but 3.12.4 is required by the SDK.

Blinky isn't blinking

Hi Scott,

Could you provide details of the board that you are using and the SDK that you are working with ?

Regards,

Hello Priyanka and thank you.

I am using a nRF52840 Development Kit Board.

The SDK I am using is:

 Using the nRF Connect SDK v3.6.99 at c:\ncs\v2.7.99-cs2

I am following DevAcadamy nRF Connect SDK Fundamentals Lesson 1 Exercise 2

When I plug my USB cord in the board does not show up in the connected devices view:

No devices found

The "code view" shows:

{

  "board": "nrf52840dk/nrf52840",

  "boardRevision": "",

  "boardDir": "c:/ncs/v2.7.99-cs2/zephyr/boards/nordic/nrf52840dk",

  "shouldBuild": true,

  "optimizations": "none",

  "cmakeArgs": [],

  "confFiles": [

    "prj.conf"

  ],

  "buildDirectory": "build",

  "kconfigFragments": [],

  "snippets": [],

  "dtcOverlays": [],

  "extraDtcOverlays": []

}

not sure the board statement is correct or does the board have a "off/on" switch?

Output "view" is:

️️ nrfjprog couldn't be executed. Please ensure that SEGGER J-Link Software and Documentation Pack and nRF Command Line Tools are both installed.

Hi,

Let us go through the issues sequentially. First, I would suggest you to uninstall everything and then start again the installation as I mention below:

1. Install nRF Command Line Tools (latest version)

2.Install the latest version of SEGGER J-Link. 

3. Install nRF Connect for Desktop application.

4. Within the application, install the Toolchain Manager.

5. Within Toolchain Manager, install the nRF Connect SDK v2.7.0

6. Now open the VSCode via the Toolchain Manager:

7. Make sure you have installed the nRF Connect for VSCode extension pack. and now you should be able to build and run your applications.

Next we can look into the DK detection issue:

Could you try with different USB cables just to cross out whether it's a USB issue. Please make sure that you are inserting the cord into the right USB port on the DK.

What is your DK revision? (details on the white sticker on the DK)

Regards,

Priyanka

Please check the previous comment in the ticket and follow the steps. Do let me know if you still face the issue after trying those. You could also try to update python, in addition to those.

Thanks to your valuable help the prior issues are resolved

Now it looks like it is compiling but fatal-ing on the flash:

It seems to me like my nRF Connect needs some issue fixes - can you advise

How do I deactivate device protection?
