Dear customer
Please ensure that you have connected the camera as outlined in section ’ 2.4.1 Connect the camera cable’ of the user manual. Kindly take a photo and upload it.
Please run the following commands to collect log and upload it:

The connection is correct. I burned the 1.1.1 firmware you released and the camera work ok, but I burn the Yocto image I compiled myself is not work.

Dear customer,
Please move the com.qti.tuned.imx477.bin file from the /usr/lib/camera directory to another location, and ensure that this bin file is not present in the /usr/lib/camera directory.
Please try it according to the documentation(Yocto 工程编译指南 | RUBIK Pi Documentation). I have no additional operations.
think you.
Dear customer
Let me confirm with you, you haven’t made any changes to the source code, is that correct?
yes，I just cloned the code and compiled it, packaged it and burned it to the board. I want you to help confirm whether other operations are required or the original repository cannot run with this operation.
