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zephyr-sdk is outdated.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 python is outdated.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:

[02:32:20] =========== Toolchain validation report for nRF Connect SDK Toolchain v2.7.0 ===========

[02:32:21] Update available nsscprodmedia.blob.core.windows.net/.../nrf-command-line-tools-10.24.2-x64.exe

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

 zephyr-sdk is outdated. Found 0.16.5-1, 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 python is outdated.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.

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

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?

Hi Scott,

In order to deactivate the device protection, you could try nrfjprog --recover, or as mentioned in the log:

Where should I get the missing software from?

[Priyanka]

You are trying "--recover" and not "nrfjprog--recover". Please try "nrfjprog --recover". This should help.
