fail to start depth stream on a single board pc

[jli84]

hi，

i try to run D415 on a single board pc (orange pi 3), and fail to start the depth stream on 1280x720 6fps. Only on 480x270 6fps it looks good.

color stream on 1920x1080 6fps runs well so i figured this is not problem with bandwidth. what's the problem then?

any help would be appreciated.

about orange pi 3,

cpu--H6 Quad-core 64-bit 1.8GHZ ARM Cortex™-A53

Memory+Onboard Storage--- 2GB LPDDR3+8GB EMMC Flash

USB 3.0 Ports --- 4*USB 3.0 Host

I know of some cases where using 6 FPS has caused problems, but it worked at 15 FPS and higher. Could you try the 1280x720 depth stream at 15 FPS please and see if it works okay? If it does, that should provide confirmation that it is the 6 FPS frame rate that is the problem.

no, it doesn't work at 15fps or 30fps

This is the first time that I have heard of the Orange Pi single-board computer (link below to the Orange Pi 3 for other readers to refer to).

As the 400 Series cameras work with any Intel or ARM processor though, the general principles involved in using a single-board computer with the camera should apply. The Viewer is showing as having a USB 3 connection in your supplied images (it would say 'USB2' beside the camera name if it were operating in the limited-capability USB 2 mode), so mis-identification of your USB connection as USB 2 instead of USB 3 is not likely to be the problem.

Dorodnic the RealSense SDK Manager has said that "In general, partial frames indicate an issue at the USB sub-system. The USB driver (or controller) are only managing to fetch part of each frame". In the discussion that this was quoted from, the user having the incomplete frames error (who was also using a single-board computer) found that the cause of the problem was that their board was overheating.
