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 Elbineser,

What board are you building for? arduino_nano_33_ble_sense? Have you tried ardunio_nano_33_ble (without "sense")? According to the zephyr documentation, that is what you should use:

https://docs.zephyrproject.org/latest/boards/arduino/nano_33_ble/doc/index.html

If so, remember to copy the boards\arduino_nano_33_ble_sense.overlay and call it arduino_nano_33_ble.overlay.

Also, did you use the application that I sent you? Where it has a while loop in the main() function? Or the default hello_world where it returns after printing once?

If you program it using an external debugger, you will probably erase the bootloader that is pre-programmed (the one that is used by the bossac tool). If you do so, you will no longer be able to program it using the arduino IDE. 

Best regards,

Edvin
