Devicetree Visual Editor: Peripherals (ADC, UART, SPI and SPI-Devices) are no longer displayed and cannot be edited

[Marko W]

I've recently encountered a problem where the Device Tree Visual Editor no longer displays any peripherals (ADC, UART, SPI), making them uneditable.

I have had my own board (for several weeks) and have been able to configure UART and ADC inputs, as well as SPI devices such as the ADXL362, MCP3208, and ENC424J600, using the visual editor.

Now, all of these peripherals are no longer displayed in the visual editor!

Hi Marko

I will report this to the Vscode team. Could you also generate the support information in VScode? 
I would also like if you could open the developer view from vscode --> ctrl+shift + p

Open the devicetree editor and post the log in case there are extra information there

Regards
