My nRF Connect for VSCode can not detect my nrf5340

[Minh0712]

I'm using nRF Connect for VSCode to program my nrf5340dk but the SDK can't detect my nrf5340 on the boards (You can see in the image). Can anybody help me to fix this problem?

I'm Minh. I am a software engineer from Bamboo Electronics JSC. I am testing on the Development Kits of Nordic (nRF5340DK). I am using nRF Connect for VSCode, I have installed all the necessary environment to program the kits. But as you can see in image, the nrf5340 chip does not show up on nRF Connect for VSCode. Please help me to check this issue and recommend for me solution to fix it

Hi

The serial number under "Connected Devices" in your app corresponds with the serial number on your DK, so this is the DK you're seeing. You can't expect the VS Code extension to know which exact DK it is communicating with, since it's communicating with the debugger MCU, and not the nRF5340 SoC itself. 

If you want to see logging from the NRF5340, you can press the VCOM0 and VCOM1 to get a logging terminal up and running which should be the NET and APP core logging forwarded to the COM ports on the DK.

Best regards,

Simon

Hi

Thanks for your reply. But normally when i plug the board in, the chip name will be displayed under the serial number, but this time it doesn't. Therefore, I can not flash my code to the kits. Can you help me to fix this issue.

Best regards,

Minh

Hmm, okay. What happens if you try to flash the board with the Erase & flash action in the VS Code extension's ACTIONS menu? Do you see any errors indicating what might be wrong with the DK?

Alternatively, you can open a terminal program and run the command nrfutil device recover to try and recover the board and see if that helps.

Best regards,
