      Hi everyone! I was working on my Spresense dev board, it has a camera attached to it with a SD Card, main board mounted on top of the extension board. Everything was completely fine until few hours back when I started working back on the board, it is not being detected. I tried this command

      $ ls /dev/tty*

      The usual output was ttyUSB0 if the board was successfully connected. I have tried changing the cables, all the cables are fine, also the blue LED is lit up on the board as usual and the 4 green LEDs blink as well as usual. What could go wrong? We're in middle of something really important and can't figure out where did we mess up.

      Thanks

        Hi @kr4tr1m,

        Do you connect the cable to the main board or to the extension board micro USB port?

        Best Regards,
        Kamil Tomaszewski
