Femto Bolt on Raspberry Pi4 ubuntu 20.02 Depth Engine Create and initialize failed, retCode:206

Technical Support & Q&A
1

Hi! I am using Femto Bolt on Ubuntu 20.02 on a Raspberry Pi 4.

I was able to compile everything and get the color viewer working. However, when I tried to run the Depth Viewer(cpp), the following error message shows:

[MSDEConverterDevice.cpp:67] Depth engine got nvram data size:492088

[MSDEConverterDevice.cpp:94] Depth engine create and initialize failed, retCode:204.

Can anyone help me solve this issue?

Thanks

Femto Bolt doesn’t support RPI4, it only supports Nvidia series arm board, like Jetson Nano.

4

Does that mean that it will not work under Ubuntu 22.04 running on a Intel I9 based machine?

5

When I say only Nvidia series, it only targeted ARM arch. Femto Bolt supports both Win and Linux on x64 platform.

Good,

I am having problems using Femto Bolt on my Ubuntu machine. I have installed the pyorbbecsdk according to the guidelines, but I receive the error message shown below when running the …/examples/depth_viewer.py example. What can be the reason?

[info][3906068][MSDEConverterDevice.cpp:94] use dynlib load depthengine lib…

Hi Nathan,

Thank you for your response. Do you know if Orbbec has tested Femto Bolt on the NVIDIA® Jetson Orin™ Nano Developer Kit? Is there anything else( configurations etc…) that i need to pay attention to when using the Nano board to develop.

Thanks,
Richard

what is your Ubuntu machine?

Same issue with Debian on Raspberry Pi 5

The color viewer is working
