Chronos User Discussion / Re: 2x2 binning on Chronos 1.4.
« on: August 15, 2019, 07:00:24 AM »
Thanks for the feedback. I have a mono camera so that will work for me.
Would be great to get a ballpark release date?

Chronos User Discussion / 2x2 binning on Chronos 1.4.
« on: August 11, 2019, 02:10:23 PM »
Is 2x2 binning supported by the sensor? if yes, is it supported by the camera?
I am primarily looking for a way to get the light sensitivity that the LUX330 has.

re.
- Standalone daemon to operate the video system, with DBus API.
Does that mean we will get a QT app soon that runs on the PC to control the camera?

Thanks for the heads up. Sounds like it's smarter for me to wait and focus on the other parts of the code I need.
I work for one of TI's biggest competitors, so getting code under NDA might be difficult :-)

That was it.
Removed "check for free space" and changed path in .pro file to target.path = /opt/camera
Deploy/Debug works fine now.

Code deep dive is up next. Need to figure out how to grab the preview video data and push that via Ethernet so I can view it on a PC and control the camera from there.

Once it's working I will be happy to show what I have and share if anybody is interested.

host = Ubuntu 16.04LTS. QT creator ver = 3.5.1.

In the .pro project file there is a target.path = /home/root/qt. that path does not exists so I fixed that by adding the qt folder.
That unfortunately did not help.
Googling the problem I found a post suggesting QT will try to load to /root.
So I created a /root folder, that did not work either.
Change install folder permission to rw access for everybody. Did not help.

Running out of ideas to try but I will continue ...

Hi foobar, thanks for the update.

The deploy/debug part does not work.
- Setup device -> works fine and "test" shows.
Connecting to host...
Checking kernel version...
Linux 2.6.37+ armv7l

Checking if specified ports are available...
All specified ports are available.

Device test finished successfully.

-> Deploy/debug generates following error. (yes i did first kill the running camApp)
16:32:53: The process "/usr/bin/make" exited normally.
16:32:53: Unexpected output from remote process: "Available"
16:32:53: Deploy step failed.
Error while building/deploying project camApp (kit: Camera)
When executing step "Check for free disk space"
16:32:53: Elapsed time: 00:00.

PS.
As far as I can see the Ethernet port works fine and actually better than the USB/ETH connection. E.g. I can use WinSCP and Putty/ssh when camera is connected to my local network with ethernet cable. As you already explained that will not work with the USB/ETH.
I tried both ETH port & USB/ETH for the debug and the result is the same.

Thanks David, (getting replies from the main dev around Christmas is unheard of, so an extra thanks for that and Merry Christmas)

That's it!
Quick hack to remove the annoying warning message about unsaved data in RAM. Built the app and tested it on the camera.
Works as expected. 

Now need to figure out a way to develop app and test without the SD card in and out copy. That works fine for a quick test but for any more advanced development I need either the camera to mount rootfs over NFS or a way to have the debugger load the executable directly to the camera.
Never used QT before but that looks fairly easy to learn. How do you develop/debug?

Best Regards
Davor

As far as I can see the SD card has 2 partitions. One EXT3 with volume name "ROOTFS" and one called BOOT. I copied the content of the ROOTFS partition.
I assumed that all files might not have come across in the copy operation (tar the rootfs and then untar on host is the way it should be done but is normally only necessary if you want to use it as a NFS for the camera during development)
So when I look for the missing header files (OMX_Types.h is the first one reported as missing) I am looking both on the SD card and the copy on my host.

Delivering the file system as a tar ball will not help if the required files are not there. Based on your response it sounds like you know they are there. So where on the SD card can I find for example the "OMX_Types.h" file?
E.g. either we need to modify the project to remove that dependency or include the files.

It's just a normal SD card that you can put in to any windows PC.
The file is just a simple text file that you can edit with any text editor.
If you want an amazing Windows text editor that is free, download this.

Yes I did copy the content of the SD card ROOTFS partion to the ...../targetfs/  folder.
Where on the SD card can I find the missing header files? I already looked in the most obvious places and did a search. 

My host machine runs Ubuntu 16.04 LTS

Thank you.
QT builds fine now and I can connect to the camera via SSH.
Next obstacle.
When trying to build the Camera app in QT creator I get an error in video.h originating from line 42 where OMX_Types.h is included.
I can't find the file so I assume that is a legitimate error and not the usual path problem.

Hooking up the mini USB to a Linux machine to get an ETH interface works fine. The camera responds to ping.
But
"You can then log into the camera using root/<no password>"
user=root, password=<nothing just press enter>
Generates an "Access denied" response.

I am using Putty as my terminal program.

Running the script conf.sh to setup the QT build generates an error. I tried to Google it, seems lots of people have fallen i this trap but failed to find a solution. I am sure it's fixable but also guess it will take a lot of time. Any chance you could update the readme with the steps required to build tslib for the Chronos apps processor or maybe even include the necessary files in the target rootfs so we don't have to build it.
The error ...
"The tslib functionality test failed!
 You might need to modify the include and library search paths by editing
 QMAKE_INCDIR and QMAKE_LIBDIR in
 /home/davor/work/qt-everywhere-opensource-src-4.8.7/mkspecs/qws/linux-omap2-g++.

Thanks!
Did a quick attempt at building the QT framework and got stuck at the step where you "make" "make install".
I will figure it out, but ran out of time, this time.
