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

Hi Edvin,

Yes i tried the application you sent in the zip file. and i built by choosing the board Arduino nano 33 BLE , previously i tried that arduino_nano_33_ble sense in the board target.


when building the application i am getting this warning does it cause any issue?:


Do we need to configure the device pid and device vid? if yes i tried that also but same result ..

for better understanding i sent you the screen record:

is there anything i should try apart from this?:

What version of NCS are you using?

Remember that you have the <board_name>.overlay, where board_name is either arduino_nano_33_ble_sense or arduino_nano_33_ble, depending on what board you are building for.

If you are using NCS 1.9.1, can you please try a later version? 2.6.3 should be a good choice.

BR,
Edvin

Hi 

I am using the latest version Edvin.



i renamed it to arduino_nano_33_ble and I don't know why i am getting this kind of warnings after few minutes of successfully built my application:


And i notice that after uploading when i check the port it show /dev/ttyACM0 for while, if i check it again it gone..

Don't worry about the warnings/errors in the "problems" tab. Does it say anything in the terminal tab when you build the sample?

I have never touched this board before, so I don't know how to use it. Are you able to open a terminal on the USB port before it disappears?

Best regards,

Edvin
