Building and flashing on separate machines

[ace.johnny]

I have access to a Linux machine for command-line Zephyr development which works perfectly, but I lack user permissions to flash my nRF5340 Audio DK and unfortunately cannot modify the environment.

I also have access to a Windows machine that has the SEGGER J-Link software pack (7.92m) installed, but no Nordic software or SDK. The Audio DK, however, conveniently enumerates as a flash drive under Windows, and SEGGER suggests that I can drag-and-drop precompiled binaries to it for programming.

Can I use this technique to flash a simple single-core Zephyr sample .HEX binary to my Audio DK? Or perhaps use one of the other Windows J-Link apps, such as J-Flash Lite, to accomplish the same without installing additional Nordic software?

I was unable to flash my Audio DK using drag-and-drop on Windows 10, however the J-Flash Lite application successfully programmed my device without issue.

I can now build Zephyr's basic samples targeting nrf5340_audio_dk_nrf5340_cpuapp on the Linux development machine, and then flash the DK on Windows using the compiled .HEX files.

I'm not sure why drag-and-drop didn't work, but J-Flash Lite is appropriately simple for evaluation purposes. Thanks for your prompt and helpful suggestions.

Ah my mistake, I just found out that we've dropped that functionality on our newest set of boards. Considering that drag-and-dropping isn't the main way we want people to program we didn't consider this to be a great loss. 

I am glad you found a way to program that works for you.

Let me know if there is anything else.
