Arduino Nano 33 BLE sense rev2 serial Monitor in zephyr envirnoment

[Ebi777]

Hi, after uploading a Zephyr project (like the "Hello World" example), I couldn't see the device in the serial monitor. i add the below commend in overlay file also but still nothing is happening i read some document says the uart stack is not enabled in the arduino board after uploading the sample code but after enabling that also same issue i am getting. 

Board: Arduino Nano 33 BLE sense Rev2 (which has nRF52840 microcontroller in it)
Platform : nrF connect sdk in vs code and zephyr environment both i tried

overlay file:

&usbd {

status = "okay";

cdc_acm_uart {

compatible = "zephyr,cdc-acm-uart";

label = "CDC_ACM";

};

};

Need to see the serial monitor in zephyr environment using Arduino Nano33 BLE sense rev 2 board.

Hello Edvin,

Thank you for sending it, but unfortunately it doesn't work after uploading i can see for a sec after that it vanished, i attached the ss for your referenc:

I don't understand how this Arduino ide programs works after uploading it i can see the serial but cant debug beacuse it doesnt comes with debugger and in zephyr environment do we need to add customize board for making it wokr.. or should we need to by the external debugger or something for serial to see the serial output in zephyr environment?

Regards,
