D456 Invalid SKU after Firmware update

Follow
Tobias Bolze

Hello,

we purchased a D456 camera and flashed a new software over windows sdk on it. Afterwards it is not reachable anymore. Propaply the firmware was not legal to the hardware. After connecting to Ubuntu it says:

usb 4-1: Product: Intel(R) RealSense(TM) Invalid SKU
usb 4-1: Manufacturer: Intel(R) RealSense(TM) Invalid SKU

The USB Cable is the original one and it is working with a d435 without a problem.

I see other posts like it suggesting opening the camera, but this will destroy the warranty. Is there any other solution out of sending it back?

    Hi Tobias Bolze  The minimum firmware supported by the D456 camera model is 5.15.0.2.  If an older firmware than the minimum supported version is installed then it can result in the Invalid SKU error. 

     

    The only alternative to voiding the warranty through disassembly is to contact the retailer that it was purchased from to enquire about an RMA return, as it is not a problem that can be fixed by users with software, unfortunately.

    Hello Marty,

    Thank you for the quick Reply we tried to install Frimware 5.16.01 suggested by the sdk tool (See image with our other realsense d435, where same software is suggested).

    I think there is still no way to change, but I´m courius why it not worked.

    Yes, the Invalid SKU problem should not have occurred when updating your D456 to the current latest firmware 5.16.0.1.

     

    Is the camera detected if you try to retrieve its information on Ubuntu with the 'rs-enumerate-devices' tool with the command rs-enumerate-devices -s
