Fairphone 2 (FP2)

Emphrath

@Luksus yes I am. This is presently the only thing keeping me from going back to UT, and I am now considering the old camera module in order to have a working flashlight... has there been a new cam module since the one we're talking about ? I was unaware. I understand that getting this flashlight to work is not a priority of this project, considering the work on halium , unity, and porting to other devices, but I can't get my head around why the former works and not this one. Maybe it requires some "porting" of its own, but since fairphone openos made the kernel sources for this device available, I wonder what's up!! I'm not a developer and only have basic Linux knowledge so I thought I could help that way.

Luksus

@Emphrath No, there were only two camera modules. I believe the biggest part of the FP2 owners have the newer one. So no need to send yours to someone.
I often thought about looking into the flashlight problem, but always came to the conclusion , if even Rajanathan did not get this to work yet, who made a lot for the FP2, then I can't make it work either....

flohack

@Emphrath the problem is that there is maybe a new flash device node in the /dev/ tree (lets assume this for a moment). However, the Android camera stack is a total mess of its own, and any slight change can totally disrupt it. I remember when the new module came out we couldnt even use it for weeks (or was it months) due to the Android part just screwing up.
Eventually someone will get it to work, but yes, our priorities are geared towards other things at the moment. But I am pretty sure @peat_psuwit could analyze it with the right module. So he might be a cndidate to send one to

peat_psuwit

Sorry, get occupied with some other stuff. I'll look into the Aethercast problem. However, that's not the top priority.

Although I've never tested the new camera module (I don't have one), I think that the stack should work with both versions. If you have the new modules and care to compile the Halium part from source, I encourage you to try it out.

For the flashlight (via the battery indicator), there's a possible fix available as the latest lxc-android-config package in xenial_-_gst-droid. Again, if you care to compile the Halium part from source, you could try that on the old and the new camera module. However, there's a possibility to burn your flash. So, please make sure you have a spare module before trying it out. I've burnt mine during my fiddling, and I have no spare module, old or new. So, I'll not be able to test it myself.

Luksus

@peat_psuwit I thought I did compile it from source, when I downloaded the linked sources of your first post and followed the Halium porting guide, didn't I?

The new camera module is working fine with the current build/stack.
Only the flash does not work.

Emphrath

@peat_psuwit you mean I should try to run android-lxc-config from terminal ? Or is it a file I need to edit ?

peat_psuwit

@Luksus Does the flash work when taking a picture normally in the camera app?

@Emphrath No. I meant that I've included a (possible) fix in the latest version of lxc-android-config debian package. If you've followed the gst-droid install instruction and upgraded your phone with apt (not system image!), the fix should be installed.

The flash in the camera app does work on my old module (at least, until I burnt it ). If even that doesn't work on the new module, then I'll probably have to find the new camera modules somewhere.

Emphrath

@peat_psuwit it does not work, even in camera app. I would gladly send the new module to you, if you wish to give it a try

Luksus

@peat_psuwit when I wrote this: https://forums.ubports.com/post/28093 - the flash was not working.

Currently I am on the legacy port again. Does the gst-droid patch work there also, or is it necessary to use Halium for it to work?

Luksus

@peat_psuwit , @Emphrath : wooow, the flash works with the camera app ... I am speechless :face_screaming_in_fear:
This is with Halium and latest gst-droid patch.

An FP2 with new camera module and working flash... I still can't believe it.
Thank you so much @peat_psuwit .

Emphrath

@Luksus awwe god !! I know what i'm gonna do back home

@Luksus hi! I would like to try your new port, is there a build image somewhere? If no, how can I install it?

Luksus

@Fla First:
it is not my port, it is made by peat_psuwit.

Second:
@Flohack, @peat_psuwit : is it ok with you if I would share my halium and system image builds in this thread? Or do you think there should be some "hurdle", so that only people "who know what they are doing" can tryout this port?

flohack

@Luksus No, but you would make a separate thread, since that one belongs to Ratchanan´s port. In general also I would love not to waste resources on 2 ports for the same device. Instead try to cooperate, make PRs and try to get it polished. There is no use in 50 different started ports but none finished. Get stuff done.

flohack

Also, please do not invest too much time in the old port. We need to bring all core devices to Halium 7.1 to see if we can fix longstanding bugs with that. So any fix for 5.1 is wasted time.

Luksus

@Flohack : oh you got me wrong a little bit. I did not create my own port.
I just wanted to host the images I built out of Ratchanan´s port, since no prebuilt images are served yet.
It is for the users, who are not able to download all sources or can't build it by themselves, but like to test the halium port.

Fla

@Luksus said in Fairphone 2 (FP2):

It is for the users, who are not able to download all sources or can't build it by themselves, but like to test the halium port.

So, exactly my case. I saw your PM, trying it right now

(And I'm interested about the 7.1 port, not the 5.1 one ;))

flohack

@Luksus Okay then sure, you can host them

Fla

I just followed the instruction and flashed halium-boot.img, the last rootfs and system.img on my device. It rebooted and... at a first look, nothing changed. I still have all my apps and data, and everything looks exactly as before... Except in the "About" page in the settings, the UT version isn't displayed anymore, and I am not able to choose any update channel in the update section, even after a reboot. How can I check I'm really on the new port?

Also, the flashlight still isn't working but I guess I need to install gstreamer-droid right?

Luksus

@Fla without looking deeper, that sounds like you flashed Halium successfully.
Yes, you need to follow the instructions of the gstreamer droid setup.
To clarify : flashlight does only work on taking a picture with camera app so far.
But I think the way isn't so far to make it work as flashlight only.
