T428 Study and Research on Experimental Firmwares

[jaygregz]

Have you tried editing '/sys/devices/virtual/display/display0.HDMI/mode'? When I set the contents of this file to '1920x1080p-50', my TV reports this exact mode and scales the display perfectly.

Someone let me know if this pans out for them too. I want to test it but I finally hava a semi-stable solution on my stick it seems.

How did you edit it? when I edit the file it does not seem to change
root@android:/data/local # echo "1920x1080p-50" > /sys/devices/virtual/display/display0.HDMI/mode
1|root@android:/data/local # cat /sys/devices/virtual/display/display0.HDMI/mode

With a little time you can have all by me.
(if it is possible and should not be in contrast with other more important things)
Don't worry. I have only two hands but i work every days.
I also have contributed enough. I think.
I also hope that someone can help me to add these other little things.
thanks.

I'M NOT ROCKCHIP , I'M STRAUZO AN USER LIKE YOU

Absolutely and I highly appreciate everything you have achieved so far! And I'm looking forward to your future work aswell! Just wanted to state other peoples thinking from a somehow more objective point of view.

I'm 100% certain that you and the other developers on this forum will bring these devices all the needed bugfixes! And it seems it's already on a good way!

Thanks again.

Someone...... help you? How could that even happen? You don't discuss your progress in any detail. You already said awhile back that you would release the info and you keep finding new reasons not to. You don't want help, in my opinion.

Add simple things to the Nexus rom, like modules and lib and tests for hardware keyboard and webcam that every advanced user can do. Also you.

If you want help in this you are welcome.

You need to remount '/sys' r/w with e.g. ES File Explorer.

What camera model do you want ? I don't have one but i can try to help you with camera.

Only for camera no bt keyboard. Because there are better mode to control an android hdmi stick.

My kernel is generic rk3188 kernel not k-r42 kernel.

In the stock rom in which camera work there are also specific library for camera ? What is the stock firmware in which your camera work ?

Tomorrow i can see this for you.

I have a Logitech C210 and a C510. Both worked fine on my RK3066 with 4.1. The C510 stopped working on the RK3188 but also on the RK3066 when I run 4.2 on it so I don't have much hope for that one at this moment (I will try to dive in the kernel sources later if I can find some time). The C210 works fine on 4.2 on RK3066 (better even than 4.1), I'm quite sure it also worked on the "Tronsmart T428 New Android 4.2 Firmware add usb audio device support" stock rom, I will reflash that one later to confirm it again, I've just flashed too many roms and kernels these weeks.

I flashed your nexus sdk2 official rom now. As expected the C510 still doesn't work, not surprising. The C210 gives image, but I can't seem to get audio.

In the stock rom's (or was it finless 1.5a) settings panel, in the sound section, there's an option to choose the sound device. Here I was able to see if the microphone of the webcam was detected. This option in the settings does not exist in your rom, so I cannot check it from there.

Can you confirm if you have this kernel option enabled? If not, then that's probably the problem.

CONFIG_SND_USB_AUDIO=y

Thanks for taking the time to check!

Hummm... I can understand why you say that, those mini keyboards are no fun. I don't have a android tablet to run droidmote though and I'm probably not the only one. I remember this BT keyboard issue was also in the early stock roms, they fixed that eventually. I'm not sure if they fixed it by changing the kernel config or actually changing the kernel code. The funny thing is, when pairing the keyboard it asks you to type a code on it, that works fine, but once it's paired it can't be used! So it might not be that easy to fix this one.

Thanks for the complete informations. I'm looking into in the next days. The only problem is that i don't have your camera but you can test for all.

Thanks

Re: T428 Study and Research on Experimental Firmwares

I understand and i'm sorry, but i would like but i can't please everyone. I look first the big problems for me and after a try to solve also other problems.

I will do my best.

Thank you. This post I perceive as a humble, anger free post. I like it.

I think that sometimes the trouble of another language can make people say some things that they probably would not say in their own language.

I trust that you will do your best to solve the things you see as problems.

I will try my best to convince you that your quest against Rockchip is a never ending one. They have unfortunately not even noticed you yet. So I fear your solution, albeit a hack according to yourself, will never reach the masses unless you change your opinion.

Signature? Signature!

Well thanks for the invite but i neither care for nor use the nexus rom. I purchase these sticks and visit this forum because I like to tinker. I currently don't need my 3188 to work as I have numerous other tv sticks that do. What I enjoy is working with a community of people and trying to make these mini pc's work better. Also I enjoy a rom/kernel that supports as much hardware as possible (input, sound, net, etc.) and isn't geared for just one or two ways to control it. Everyone uses these things in different ways and nobody's personal preference should be shot down just because there are "better ways" to control. To each their own. I prefer keyboard/touchpad combo personally.

Thanks though.

Sure, just post a kernel or rom and I'll flash it. I stopped using the T428 for daily usage anyway, I switched back to my MK802III for that.

Make sure both of these are enabled:

CONFIG_SND_USB=y
CONFIG_SND_USB_AUDIO=y

For some reason the defconfig only has the first one enabled. I suspect that's the only thing they changed in their last firmware release.

Thanks again. This is what i want from other users that requesto to me things. i want help and suggestions, because also if are simple things, there was time to compare and test.

i can not do everything alone.

Tomorrow morning italy time i see into this problem and i can look into the .config and i can look into the rom in wich work to see if there are also other files / libs necessary for the operation.

you can use all that you want for sure. my is only a suggestion and nothing more.

Only for curiosity, howdo you use in your mini pc apps like google maps, google earth, pinch to zoom in browser, google plus, or all other tools, apps and games that need multitouch actions.

but multitouch actions in a precise point , and not a fake multitouch in wich you don't see where you touch.

Maybe all we do is play videos, on demand tv programs, use skype and browse through the app store ;-)

My mini keyboard has some tricks to make certain things easier but it can't beat full multi touch of course.
