hello everyone, I have designed a PCB board, there are some problems.

1. when I download the official firmware,the board can show usb3.0, and bulkloop and streamer work ok.

2. when download our firmware, it just work 3 seconds, but when download the same firmware to another board, it works ok.

I can't find which I can do to solve this problem.

     thanks!@

Hello,

Since you have mentioned that all PCBs show the failure symptom, please ensure that the board is designed in accordance with the guidelines mentioned in the AN70707.

Best regards,

Hello,

- Please let me know if your custom firmware is failing on only one board.

- Share the firmware source code if possible. Else, share the IMG file.

- When using the Control Center, does the device disconnect and re-connect again or is it not re-connected? Please check the device manager for the presence of the device.

Best regards,

Hello,

- After re-connect, does the device with the new firmware show up in the device manager?

- Share the firmware source files or the IMG file for testing at my end.

- Also, share the board schematics corresponding to FX3 connections.

Best regards,
