I have enabled the ov5640 now. it works well. Thanks



2014-07-13 0:34 GMT+08:00 jonsm...@gmail.com jonsm...@gmail.com:

 OV5640 is a parallel interface camera sensor.

 I believe the latest Allwinner A20 camera code is in the A20 SDK 2.0.
 https://dl.linux-sunxi.org/SDK/A20-SDK-2.0/

 I don't have it downloaded on this machine. Maybe someone else has it
 broken out and can just sent you the relevant files. Inside that 6GB
 file is the Android tree and a kernel tree.

  Yes, ov5640 is connected with CB2 pins by fly lines.
  Can you share the camera driver which enables the ov5640?
  I am trying to enable ov5640 but failed now.
  Thanks in advance

  Only ov5640 I have is the one in the EU3000. It works with the
 
  standard Allwinner Android image.
 
 
 
  So you build some kind of converter board from a FPC cable to the CB2
 pins?

I am debugging ov5640 on CB2 now.
 
Who have enabled the ov5640 on CB1 or 2 successfully? Hope you to

   How did you attach the sensor to the CB2?

In July 2005, after several failed attempts to legalise software
patents in Europe, the patent establishment changed its strategy.
Instead of explicitly seeking to sanction the patentability of
software, they are now seeking to create a central European patent
court, which would establish and enforce patentability rules in their
favor, without any possibility of correction by competing courts or
democratically elected legislators.

It was announced in June (http://www.allwinnertech.com/plus/view.php?aid=398)
and just now it has gone in mass production (
http://www.allwinnertech.com/plus/view.php?aid=407).
ARMDevices.net has several articles and videos about the A33, with details
on how Allwinner plans to flood the market with A33-based products in the
coming weeks.
Apart from reduced power consumption, there are no AnTuTu scores yet for
A33 devices.

Ok. Do you still want the error reporting for the invalid width and
burst size?
   I think for convert_buswidth() we can do away with a switch case and 
   convert
   the numbers directly
  
  Well, it's already using a switch. Do you want me to remove completely
  the function and move the switch where it's used? It's used two times
  now, so I'd like to avoid duplicating it.
 You can probably remove switch in these function by converting them
 arithmetically..
 
 - don't use devm_request_irq(). You have irq enabled and you have 
 killed
   tasklet. This is too racy. You need to ensure no irqs can be 
 generated before killing
   tasklets.

Ok, would calling disable_irq before killing the tasklet an option for
you ? that would allow to keep the devm_request_irq.
   disable_irq also does syncronize, so it might work. But then again if the
   probe fails after registering irq due to some other reason, and you get 
   into
   races with unitialized driver as well.
   
   I think it might be easier to amnge by working with plain old 
   request_irq()
  
  Yes, devm_free_irq like Russell suggested seems to both address your
  concerns, while not having to care about it at probe.
 OK, pls send the fix

Ok, will do tomorrow.

 Seems to be the same story as A10-A20 with the A33-A23 substituability.

Now if only we didn't have massive allwinner gpl violation in that a23 
kernel tree we have.

Also, the only person working this platform is wens, and he is going

we really are not in a position where we should be overly happy about 
the a33 release.

Does any of it even build? I've never tried, and by the looks of the 
wiki, i'd say no-one else ever did either.

When the build fails it is missing the mali stuff. You have go get
that from the ARM servers and add it in. You have to do that for every
TAR ball they release because of a mess with the redistribution
license and ARM Inc.

 Seems to be the same story as A10-A20 with the A33-A23 substituability.

 Now if only we didn't have massive allwinner gpl violation in that a23
 kernel tree we have.

Is this something we could take to Linaro? Do they do anything about
GPL violations?

Thanks,

I'm not clear on where the GPL violation is. AFAIK the problem is with
ARM, Inc and Mali. Good luck on getting them to open source. Allwinner
has no control over what ARM, Inc does with Mail source code.

Might be a few drivers missing like on the A20. But AFAIK they are
missing because they have never been written, not because they are
being withheld. For example TVIN on A20.

I assumed there was something more serious than just missing Mali bits.
