I have flashed the zephyr project sample application on my Arudino nano 33 ble sense using the instructions provided in the zephyrproject page (Arduino Nano 33 BLE (Sense) — Zephyr Project Documentation). i have flashed via /dev/ttyACM0 over usb to usb-mini cable connecting my arudino to my laptop.
Once flashing is done, CDC_ACM port is lost and cannot be found either in dmesg or arudino IDE and hence i have connected usb-ttl cable by connecting only RX/RX pins from my board to my cable and running minicom with 115200 8N1 configuration.
I tried both the options still no luck.
- powering my arduino using the USB able and connecting only RX/TX pins on ttl cable.
- connecting all 4 pins on my usb-ttl cable to my arudino so that power and data available from ttl cable.
Still i don't see any output on minicom.
So my question is,
- is my usage of usb-ttl cable is correct? if so, then any configurations that needed to be done
- how to enable CDC_ACM once my flashing is done so that i can avoid usb-ttl completely.
