cannot flash hello_world, this time on Windows 11

[Brian Fuller]

My computer is running Windows 11. The board is an nRF9160-DK.  I'm working through VSCode environment. All nRF libraries are up to date according to RF Connect for Desktop v4.1.2.

I created a new application and used the hello_world template. Here is the code for hello_world.

#include <zephyr/kernel.h>

int main(void)

{

    printk("Hello World! %s\n", CONFIG_BOARD);

    return 0;

}

The code compiles successfully by using the Build button in the Actions section of the UI.

Then I push the Flash button in the Actions section of the UI with the following output to the terminal window.

 *  Executing task: nRF Connect: Build: hello_world/build (active)

What is the target/board in your build configuration on gui in the VS code extension?

If you're trying to flash the nRF52 on the board, there's a build target for that. (And you need to flip the PROG/DEBUG white switch SW10)

If you're trying to flash the nRF9160, then there is a different target for that. (As well as a secure and nonsecure target)

Based on your error, I could replicate this if I tried to flash the nRF52, and the nRF52 was the build target, but the switch was flipped to nRF91 for programming.

EDIT: I see here that you were able to resolve, and build target was indeed the issue.

Best wishes.
