Failed to find device after booting

Tjjl

Hello, I'd like to ask about a recent issue. I received a new FFC-4p R1M0E3 board recently and used the Flash Bootloader. After testing, I connected a camera and it was able to run a demo. However, today when I tried testing again, I encountered the following error: when I unplug the camera and run System Information, it runs successfully. But when I plug in the camera and run System Information, the same error occurs. Even when I connect an IMU separately, without the camera, I can read IMU data. However, when I insert the camera, the same error occurs. When running System Information, I haven't defined any camera nodes; I've just connected the camera to the carrier board. Could you please advise on what I should do?

Hi @Tjjl
Sounds like a power issue. Can you use a different adapter / supply to verify?

Thanks,

jakaskerl Thanks，However, I also purchased the same model of the product in January, and under the same conditions, the one I recently purchased has issues while the previous one did not.

Hi @Tjjl
Was the revision number the same? R1 is a very old device.

Thanks,

jakaskerl Yes, it's all R1M0E3

Hi @Tjjl
I think the reason the device boots without the camera is because there isn't enough power supplied when the camera is plugged in. Which camera are you using? Could you try swapping the power supply with the working unit?

Thanks,
