[Dev][OV5693] Backcam fix - G Pad 8.3 Android Development

So,
the G Pad (v500) comes with in two versions.
One version has the S5K4E5YA as back camera.
Other version hast the OV5693 as back camera.
As we know the S5K4E5YA already has support in AOSP and CM ROMs and kernels.
So I tried to add the missing files and references to the CM kernel.
https://github.com/drbeat/kernel_lge_v500/commit/7c9beb4a27fc65b60786616c5c966e53632dfc5d
These are changes I picked out from the "V50020D" kernel sources.
In compiling I get this error
Code:
drivers/media/video/msm/eeprom/ov5693_eeprom.c:68:2: error: extra brace group at end of initializer

Am I missing some changes?
Maybe someone know how this can be fixed so everyone gets the same experience.
EDIT:
OK I got it compiling.
https://github.com/drbeat/kernel_lge_v500/commit/7fce6ccd0c82fcdb17c22f4053db4d6703f1c436
Now I need someone with OV5693 to test it out
EDIT 2:
The binaries may be lacking.
I will look into that
EDIT 3:
So I have made a ZIP containing binaries and a kernel with ov5693 drivers
I need someone to test it out
DOWNLOAD: removed!
will upload a new version soon
EDIT 4:

I thought ov5663 was the one that does not work. Here is a log for a ov5693 working with stock AOSP.

there is no "ov5663"
the back camera which is not working is "ov5693"

---

Then I'm curious why the person who posted that log says his cameras are working.

so to clear it up for you
front cam is always "IMX119"
back camera is either "S5K4E5YA" or "OV5693"
there is no "OV5663"
that guy posted dmesg before he flashed AOSP
since his back camera is working he has a "S5K4E5YA" module
just ask him to do another dmesg now. you will see that his results will be IMX119 and S5K4E5YA since AOSP and CM dont support OV5693

---

Thanks for clearing that up. I'm sure lots of others were/are confused too.

---

I bet of you changed the title of this thread to something like "fix for back camera" then people would understand the purpose of this thread better and offer to test.

i still have to find the right binaries to make a working zip

---

I have a 50020D, I'll take it for a spin and report back later.
UPDATE: I got stuck at boot logo after flashing, but I managed to restore from my backup.
To tell the truth I'm not using stock CM, but a Team Vanir/Commotio ROM. Although they supposed to be using the same kernel and device tree as CM.

thx for reporting
do you have a backcam which is not working?

Yeah, I do.
It's only working on stock ROMs, so I guess its the same.
If you can tell me how, I can send you a log or something to help you.

uploaded a new zip
this one doesnt give bootloop.
still do a backup and report back please

can some one that has ov5693 please test this zip and see if the cam works
it uses the same kernel that ckret has in his zip file
the only thing I added was more of the camera binaries from 20d
make sure you back up first
https://www.mediafire.com/?gx83ty2ytxdc2wt

---

I tried it but it got me into a boot loop.
I hope you figure it out \o
PS: Using Mahdi's Kit Kat Rom.

---

thanks for testing, sorry about the loop
since I dont have this phone, I dont think I will be able to help much more, sorry

I looked at your kernel commit and that looked to be right
those files I have in that zip are the correct libraries
what it is probably missing is a key in the lib camera client
there is most likely a message in the logcat that says it could not load camera.msm8960.so because it could not find a key
usually these keys could be added to
frameworks/av/camera/CameraParameters.cpp
and
frameworks/av/include/camera/CameraParameters.h
but then you would have to build cm11 again
I am pretty sure the only way you are going to get the back cam to work is with those libraries
if you grep for ov5693 in the original files / libraries it probably will not be found, if you grep the 20d files, you should find it listed in the mm-qcamera-daemon, liboemcamera.so and the 3 chromatix files

its propably selinux and permission related
this most time cause bootloops

idk
would need to see a logcat to be sure
