Unable to initialize camera sensor from linux library

[joncppl]

I'm using the USB3 variant (rev. c) with MIPI adapter board connected to an OV5647 (rpi "spy cam")

Running the demo program sudo ArduCam_Demo ../../../cpp_config/OV5647_MIPI_RAW10_edit.yml yields:

Serial: AU3S-1903-0010
capture thread create successfully.
read thread create successfully.
Capture began, rtn_val = 0
Error capture image, rtn_val = 65318
Error capture image, rtn_val = 65318
Error capture image, rtn_val = 65318

From the header I can tell that 65318 == 0xFF26 == USB_CAMERA_USB_TIMEOUT_ERROR, which I find insufficiently informative.

However, I tried the Windows USBTest GUI/MFC application with OV5647_MIPI_RAW10.cfg, and it worked.

Strangely, when I booted back into linux, ArduCam_Demo now works with the same configuration file.

I thought my problem was solved until I power cycled the ArduCam. It reverted to no longer working in Linux.

I repeated the process, and determined that running the USBTest application once in windows consistently enables it to then work in linux.

I have repeated this cycle on up to date Arch/Manjaro, Ubuntu 18.04, and Ubuntu 16.04. All exhibit the same behaviour.

Any advice?

(This is proving difficult for me to debug since the source for libArduCamLib.so is, as far as I can tell, unavailable)

[ArduCAM]

Sorry for my late reply. It seems like the configration file for linux is not correct, we will verify the config file next week then get back to you.

[ArduCAM]

Please check the update config file and SDK library.

[joncppl]

Thank you for your response.

Unfortunately, the update did not solve my issue. I pulled the latest git repo, rebuilt the demo application, and still get the same error message.

I tried the updated library in Windows, it still works,

Press ENTER to exit...

I rebooted into Linux, it worked once. I unplugged/plugged back in the ArduCam, then I get error 65318.

Any new information?

[UCTRONICS]

@joncppl Please try this configuration files OV5647.zip

[joncppl]

Thank you for trying to help me work through this issue.

I tried both configuration files. Neither succeeded in initialising the sensor in Linux. Both worked in Windows, however.

I believe the problem is that the sensor is not receiving the I2C commands when initialised by the Linux library.

For example, If I use Arducam_test.exe OV5647_MIPI_RAW8_usb2.yml from windows, it works in 8 bit mode.

If I switch over to Linux, and then use ./ArduCam_Demo OV5647_MIPI_RAW8_usb2.yml, it works. But if I immediately use 10bit mode ./ArduCam_Demo OV5647_MIPI_RAW10.yml, I get the error USB_CAMERA_DATA_LEN_ERROR RECEIVE_LENGTH:2510928

Hence I think the sensor never received the I2C commands setting it to 10bit mode.

[joncppl]

I will try the 8bit mode configuration with the USB2 revision of the ArduCam and see if I can get a framerate acceptable for my application, since the USB2 revision is working fine with Linux.

@joncppl OV5647_MIPI_RAW10.zip

[UCTRONICS]

@joncppl Do you connect the USB2.0 or USB3.0 interface?

[joncppl]

I'm afraid I am seeing the same result with the most recent configuration.

I am connecting the ArduCam to a USB3.0 port (not a hub). The OS detects it as "SuperSpeed Gen 1 USB".

In the demo code cameraCfg.usbType is USB_3, so "board_parameter_dev3_inf3" is loaded, if that helps.

[UCTRONICS]

@joncppl This problem is very strange, we in the start interface test is no problem, only on the USB2.0 interface bandwidth problems, I wrote a simple detection function to test the register write and a few small changes have been made to the configuration file (I'm not sure whether he will be able to solve your problem), using make ArduCam_Demo_test compiled test program, using methods and ArduCam_Demo is the same, this is my operation: Streaming_demo.zip

[joncppl]

Interesting results

ArduCam_Demo_test works!

I believe the cause of the change is that configBoard is called after writeSensorRegs in the test code.

[UCTRONICS]

@joncppl This is a very strange phenomenon. If so, Windows should have the same problem with the instance program. And it does not have this problem on my ubuntu16.0. I will continue to trace this problem.

Any update?
