Can not run libuvc_installation.sh normally #12925

Hello,When I'm running realsense-viewer,it shows like this: IMG_5982

21:12:39 [Info] /tmp/sandbox/src/linux/backend-v4l2.cpp:753 - Enumerating UVC video0 realpath=/sys/devices/platform/5fb80000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/0000:02:00.0/0000:03:00.0/usb1/1-2/1-2:1.0/video4linux/video0 21:12:39 [Info] /tmp/sandbox/src/linux/backend-v4l2.cpp:753 - Enumerating UVC video1 realpath=/sys/devices/platform/5fb80000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/0000:02:00.0/0000:03:00.0/usb1/1-2/1-2:1.0/video4linux/video1 21:12:39 [Info] /tmp/sandbox/src/linux/backend-v4l2.cpp:753 - Enumerating UVC video2 realpath=/sys/devices/platform/5fb80000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/0000:02:00.0/0000:03:00.0/usb1/1-2/1-2:1.0/video4linux/video2 21:12:39 [Info] /tmp/sandbox/src/linux/backend-v4l2.cpp:753 - Enumerating UVC video3 realpath=/sys/devices/platform/5fb80000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/0000:02:00.0/0000:03:00.0/usb1/1-2/1-2:1.0/video4linux/video3 21:12:39 [Info] /tmp/sandbox/src/linux/backend-v4l2.cpp:753 - Enumerating UVC video4 realpath=/sys/devices/platform/5fb80000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/0000:02:00.0/0000:03:00.0/usb1/1-2/1-2:1.3/video4linux/video4 21:12:39 [Info] /tmp/sandbox/src/linux/backend-v4l2.cpp:753 - Enumerating UVC video5 realpath=/sys/devices/platform/5fb80000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/0000:02:00.0/0000:03:00.0/usb1/1-2/1-2:1.3/video4linux/video5 21:12:39 [Info] /tmp/sandbox/src/context.cpp:128 - Found 0 RealSense devices (0xfe requested & 0xff from device-mask in settings)

Then I search online for the problems,I try to run libuvc_installation.sh,but it didn't run normally

` linaro@bm1684:/data$ sudo ./libuvc_installation.sh

for more information

linaro@bm1684:/data$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04 LTS Release: 20.04 Codename: focal linaro@bm1684:/data$ uname -r 5.4.217-bm1684-g70a3e20060f6-dirty

Can you give me some advice ,please

I am using D435i

Hi @DiopWang This error does not usually occur when using the libuvc_installation.sh script. My research of non-RealSense Linux cases indicates that when this error does occur, it is caused by the instruction sudo fallocate -l 2G /swapfile. In the libuvc script it can be found on line 26.

Replacing the sudo fallocate command with the one below can resolve the error.

sudo dd if=/dev/zero of=/swapfile bs=1024 count=1048576

@MartyG-RealSense Hi,I am really thank you for your response.However,I did what you told me,it still show swapon: /swapfile: swapon failed: Invalid argument. Can you tell me what can I do in other way?Thank you so much c8f3798dcb6fa0d47821f10c3ce0baf

If you comment out the entire swapfile mechanism in lines 26 to 30 then is the libuvc script able to complete sucessfully?

@MartyG-RealSense Yes,I comment out it,and it can work,and Librealsense script completed But when I am running rs-enumerate-devices,it still did not work. To be honest,I have tried almost every methods in last 4 days cfc29177543431522a7896173ccebb4

Could this be the cause of the system kernel, such as no corresponding drivers?

MartyG-RealSense commented 6 months ago

When using a libuvc installation of librealsense the kernel should not matter as librealsense bypasses the kernel.

Are you using the official 1 meter USB cable supplied with the camera or a longer USB cable of your own choice?

What is the computer that you are using your D435i on, please (Raspberry Pi, Nvidia Jetson, desktop / laptop PC, etc)

Is the cable plugged into a built-in USB port on the computer or a USB interface such as a hub or PCIe?

Are you using the official 1 meter USB cable supplied with the camera or a longer USB cable of your own choice?您使用相机随附的官方 1 米 USB 线还是您自己选择的更长 USB 线？

What is the computer that you are using your D435i on, please (Raspberry Pi, Nvidia Jetson, desktop / laptop PC, etc)请问您使用 D435i 的计算机是什么（Raspberry Pi、Nvidia Jetson、台式机/笔记本电脑等）

Is the cable plugged into a built-in USB port on the computer or a USB interface such as a hub or PCIe?电缆是否插入计算机上的内置 USB 端口或 USB 接口（例如集线器或 PCIe）？

I am using official cable,and plugged USB3.0 port,but ubuntu shows it only used USB2.0 port, It is using a development board called "Shaolinpai" which designed by sophon company

MartyG-RealSense commented 6 months ago

Are you using Sophon's SLKY01 Shaolin Pai board at the link below?

https://en.sophgo.com/product/introduce/slky01.html

It appears to use a Sophon chip called BM1684 as its CPU. The librealsense SDK is intended for use with x86 / x64 CPUs (like those in desktop and laptop PCs) or Arm CPUs (such as those in Raspberry Pi and Nvidia Jetson boards). If the BM1684 CPU is neither x86/x64 or Arm chip architecture then librealsense may not know how to make use of it. It looks as though the BM1684 chip was designed to specialize in processing deep learning activities rather than general computing activities.

yes,it is a TPU chip.Thanks for your help
