Raspberry Pi Camera with Tinyrex UltraModule and Baseboard Lite
r.valvekar_Nexustec , 09-29-2017, 04:34 AM
For last couple of days I have been trying to start the Raspberry Pi Camera Module V1.3 with Tiny Rex Ultra and Baseboard Lite. The following are the details of the Operating System that I am using:
Linux Lubuntu with linux-fslc-4.1-rex Kernel.
I did try to test the camera with the testing procedure that is provided on the voipac website wiki in the section CSI on this website http://wiki.voipac.com/xwiki/bin/vie...inyrex/testing
The camera module gets detected on the i2c bus with UU at 0x36. The results of lsmod also shows the same as per the testing screenshots. But when i use gst-launch, the camera is powered up for few seconds and it turns off, without any image on the screen.
I dont know if any one has tried using a raspberry pi camera module on tinyrex, but this is where I am stuck. I was also checking if I could get any images for the operating system, which i found on the github on this link https://github.com/voipac/imx6tinyrex_bin_linux, but unfortunately there are no images for tinyrex ultra. I could use tinyrex max on tinyrex ultra, but most of the functionalities are non-functional. Plus i noticed that i cannot use apt-get and dpkg since, they were not found.
On other hand, I also tried installing Android which is provided by Voipac, but the system does not support the camera module.
I am looking forward for some positive help, solution or even links to drivers.
Thank You

Yocto DEMO images are stored here:
Yocto DEMO images are used to evaluate peripherals and testing only.
This is the camera log running fsl-image-gui-imx6-tinyrexultra-2.3.sdcard image. Some images were displayed but it was very slow and choppy.
Camera driver is from here
In the case the camera is working under yocto and not working under ubuntu then the difference is most likely in gstreamer. The kernel driver might be missing proper callbacks to satisfy gstreamer startup calls to setup camera. I can't help to investigate what is missing because i know nothing about it.
