Hi everyone, I just bought a new Arduino Nicla Vision. When I first connected it to my laptop it shows red LED for 14s. Then when I remove it and insert again, the Nicla Vision can be connected and can run the code as usual. Then I remove it when I’m done and try to connect it the next day, the red LED lights up again. Anyone know why is this happening and how to solve it?
Did you install our firmware on it ?
Yes, I installed already, but still having the issue
What I meant is, did it flash the red LED out of the box or after installing the firmware ? Does it show up in dmesg or the device manager etc… ? You need to provide some more details so we can try to help you.
I am sorry cuz I’m quite new to OpenMV. What happened to me is when the red LED shows, my laptop literally cannot detect the connection. And it shows

That’s okay, but that’s not what I’m asking. I’m trying to determine if you received the board in that state, if so it might be faulty for some reason, or if it’s started to flash the red LED after trying to flash the firmware. So asking again, did it flash the red LED when you first connected it to the PC or after trying to upload the firmware ?
Can you run the bootloader ? Just press the reset button twice quickly, it should start blinking the green LED, then if you try to connect from the IDE it should recover it.
Can you upload any Arduino sketch ?
It happens when I first connected to the PC. For the bootloader, it works. However, sometimes I can connect from the IDE but sometimes the red LED still showing. So far I have no any Arduino sketch, just try to connect from OpenMV IDE only
Try updating the bootloader:
Done this but still having the problem

Bootloader update complete. It's now safe to reboot or disconnect your board.
after disconnect and reconnect the board, same problem still exist
Hi, unfortunately this isn’t really related to our tools but what Arduino supplied us.
The issue you are seeing is that packets are being corrupted on the bus and/or some type of timeout is happening. The DFU software updater is not handling this well and crashing. What I’ve seen fix this issue is to use a different USB cable and or computer.
I have run into this issue previously before however and it’s pretty random on how you get past it. Like, for example I’ve restarted the PC and then it goes away sometimes.
… I do have a USB analyzer so the next time I encounter this happening again a lot I can trace what the exact issue is. However, I don’t have the ability to modify the source since it’s inside of the third party DFU loader program.
Alright thank you
@yeongmingg You should try to upload an Arduino sketch see if it works, if not or you still see the red LED flashing you should contact Arduino’s support, they can help you or replace the board for you if needed.
