CDC ACM UART missing dependency

Hello,

I think this is rather a device tree configuration. What board file do you use in your project (.dts or .overlay files)?

Best regards,

Hi. I solved the problem. I cant run these three CONFIG options enabled = CONFIG_DEBUG=y, CONFIG_LOG=y, CONFIG_LOG_MODE_MINIMAL=n. If I enable them, CDC ACM UART doesnt work. Do I need to set some additional CONFIG options or debug and logs doesnt work over CDC ACM UART? Thanks.

Hello,

I don't suppose I would be able to reproduce what you are seeing on an actual nRF52840 DK?

[quote user=""]

After build I am getting this error:

"CONFIG_UART_CONSOLE was assigned the value y, but got the value n. Missing dependencies: SERIAL_HAS_DRIVER",

[/quote]

It looks like something is missing in your boardfiles. Is it possible for you to zip a project that I can unzip into my unmodified SDK to replicate the issue? If so, can you please upload it, so that I can have a look at what you did with your board files?

Best regards,

Edvin

I was also trying using the nrf52840dk_nrf52840 board file as my build board. I didnt get the problem above but after flashing the board with CDC ACM UART Sample I am getting problems with USB recognition, the problem is:

A request for the USB device descriptor failed. (Code 43)

These are outputs from USB Device Events:

I also cant see any COM port. Is it possible that there is some problem with hardware? Mybe bad USB-C connector or something.... Thanks for answers.
