No image on both Windows 10 and Ubuntu 20.04 - PureThermal-2 with Lepton 3.5

[Werterror]

Hi all, I first tried on Windows 10 and I have the same issue as @Nomad described here: https://groups.google.com/g/flir-lepton/c/NnLDO1Ua4ss Camera is visible in both CCI and Camera Feed selection, LED is lit constantly and shutter closes for a second periodically, but there is no image, just grey square in the middle.

So I tired with Linux Ubuntu 20.04, I follow steps that are described in Readme file. Everything goes through without any errors. I run: sudo ./GetThermal - That is located in /GetThermal/build/release and this window opens: Theres is no image, GetThermal returns onto terminal: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' UVC initialized Device found Device opened DEVICE CONFIGURATION (1e4e:0100/8005800e-5113-3238-3233-393800000000) --- Status: idle VideoControl: bcdUVC: 0x0100 VideoStreaming(1): bEndpointAddress: 129 Formats: UncompressedFormat(1) bits per pixel: 16 GUID: 5559565900001000800000aa00389b71 (UYVY) default frame: 1 aspect ratio: 0x0 interlace flags: 00 copy protect: 00 FrameDescriptor(1) capabilities: 02 size: 80x60 bit rate: 691200-691200 max frame size: 9600 default interval: 1/9 interval[0]: 1/9 UncompressedFormat(2) bits per pixel: 16 GUID: 5931362000001000800000aa00389b71 (Y16 ) default frame: 1 aspect ratio: 0x0 interlace flags: 00 copy protect: 00 FrameDescriptor(1) capabilities: 02 size: 80x60 bit rate: 691200-691200 max frame size: 9600 default interval: 1/9 interval[0]: 1/9 FrameDescriptor(2) capabilities: 02 size: 80x63 bit rate: 725760-725760 max frame size: 10080 default interval: 1/9 interval[0]: 1/9 UncompressedFormat(3) bits per pixel: 8 GUID: 5938202000001000800000aa00389b71 (Y8 ) default frame: 1 aspect ratio: 0x0 interlace flags: 00 copy protect: 00 FrameDescriptor(1) capabilities: 02 size: 80x60 bit rate: 345600-345600 max frame size: 4800 default interval: 1/9 interval[0]: 1/9 UncompressedFormat(4) bits per pixel: 16 GUID: 5247425000001000800000aa00389b71 (RGBP) default frame: 1 aspect ratio: 0x0 interlace flags: 00 copy protect: 00 FrameDescriptor(1) capabilities: 02 size: 80x60 bit rate: 691200-691200 max frame size: 9600 default interval: 1/9 interval[0]: 1/9 UncompressedFormat(5) bits per pixel: 24 GUID: 7deb36e44f52ce119f530020af0ba770 (}�6�OR��S) default frame: 1 aspect ratio: 0x0 interlace flags: 00 copy protect: 00 FrameDescriptor(1) capabilities: 02 size: 80x60 bit rate: 1036800-1036800 max frame size: 14400 default interval: 1/9 interval[0]: 1/9 END DEVICE CONFIGURATION Initializing lepton SDK with UVC backend...

I also tried running GetThermal.pro with QT, which opens similar screen:

It seems like resolution might be the problem, which is 160x120 for Lepton 3.5 and software expects 80x60. I have check the cable with a mobile phone and I am able to transfer data via it.

same problem here on debian bookworm

doesn't solve the issue and, anyway even if it would solve it I do not want to run a gui as root

@Werterror @xevilstar What purethermal firmware are you using? I had camera feed working in GetThermal on Ubuntu with FW v1.0.0. I updated FW to v1.3.0 to get radiometry working, and I got the same 'UVC_GetAttribute failed: -9' errors. Camera is still working as plain UVC (for example on https://davidwalsh.name/demo/camera.php), but no image at all in GetThermal

[kubabuda]

By the way, firmware v1.0.0 also was causing me 'UVC_GetAttribute failed: -9' errors - on older laptop, when PT board was connected to plain USB2.0 port. After I connected PT camera to another, USB SS port, the problem went away (with v1.3.0 on my laptop unfortunately it does not help)

[kubabuda]

I downgraded PT firmware to v1.2.2 and GetThermal v0.1.3 correctly displays image - maybe there is problem with new USB descriptors added in FW v1.3.0?

[xevilstar]

how can I know which firmware I am running ?

[kubabuda]

Launch GetThermal from terminal, somewhere in log you will get something like

'Initializing lepton SDK with UVC backend... Using GroupGets PureThermal (fw:v1.2.2) with firmware [...] OK

[zhaocundang]

how do you make it on WIN10
