Yes definitely the Carpad3 has a mic built in. At one point Summer said it worked for voice control with Chinese but not with English and asked for suggestions. I suggested just using one of the existing apps out there and not reinvent the wheel.

I really have a feeling that the Carpad3 will be an all in one unit. The images show a microphone hole on the front of the unit and an SD Card slot on it. There's definitely enough space in there for it.

It would likely solve a lot of installation issues too, so many people didn't understand why the box wouldn't work without the Android box plugged in. I even had one person return a unit because their professional shop couldn't get it to work. When it was returned it was obvious the Android box had never been taken out of the box at all.

No clue, but I'd grab a breadboard and build a resistor ladder on it and try some different values. I suspect it won't really matter too much. I've thought about building a SWC simulator for testing the software, but it's on a long list of things to do. When I've needed to test something key press related I've just been using IR.

Hey Usafle, i've also installed a aftermarket amp and sub. I Also followed your instructions but if i play some Music (Spotify), it doesnt matter what kind of settings i change, nothing happens! The Driver Says at Processing NO.

Please help me what can i do?

I am using Tuataras Rom on the Newsmy 2GB Version...

Thanks!

For my older HU I have already set up a circuit which was from 1kohm to 4 kohm for both SWC cables seperately. It has four buttons for each cable. I never changed anything and connected to this HU as is. It worked.
[Android Head-Units] Bokomaru:
I'm curious. How are you getting the logcat? Are you leaving USB plugged in from a laptop the whole time or grabbing them later?
[Android Head-Units] VBlack:
I have router with usb modem inside the car. In android installed "wifi adb". Turn it on, and you could connect adb through internet...

And I'm just thinking... MCU is general purpose STM32 chip - and should not do too much work actually (switch audio/video routes, maybe handle SWC, etc... ) is it worth to just write our own 'firmware' for it?
[Android Head-Units] Bokomaru:
Just wanted to make sure you weren't continuously connected via USB and supplying power to it which changes the behavior.

Yes it is possible to write our own firmware for it, but it would be a pretty major effort that I wouldn't even consider unless there were a significant number of people contributing to it.
[Android Head-Units] VBlack:
About MCU firmware real question is we really need to have it in source (some issues, features which newsmy don't want to fix/implement). Or it is just "nice to have"? From my point of view at least protocol between MCU and Android should be more stable (now it is more like UDP, we write something and does not know is it received or not). Write firmware by itself is not big problem, but we need some documentation (head unit schematics is really nice to have for this) or just by looking to pcb (but for this need spare HU pcb - I don't want to remove carpad from car).

Just wanted to download the xdauto 1.1.6c img file but dthe download stops at 483MB and crashes then.

Does anyone have a working download link or could upload the img file?

Thanks!

EDIT: Worked after several trys. BUT

in RKBatch Tool it fails at "Firmware Download Start" . After 100% it fails.

Maybe the downloaded File is defect on the server?

Please help me!
[Android Head-Units] TheLoverMan:
anyone else on windows 10 who can use RKBatch Tool ?

EDIT

Sorry i do mean the drivers not the tool
[Android Head-Units] TheLoverMan:
Ok anyone who might find this and had the same problems as me, if you use vmware workstation 12 player on windows 10 then run windows 7 iso after the install just plug in the android box and it will auto find the drivers and install. Boom RKBatch Tool works.

EDIT - Seem the tool works and picking up android box but still says driver not installed.

[Android Head-Units] TheLoverMan:
This photo of "RKBatchTool v1.6" running as admin on virtual 7... should it not show info of my android box like version of FW ?
[Android Head-Units] Bokomaru:
There are some improvements that could be made, but for me personally everything is good enough to get by. I think an ACK of TX/RX via the serial would be nice, but I don't think it is completely necessary, there generally aren't a lot of messages going back and forth. If this was implemented I would add a bit for messages that didn't require ACK, like GPS messages which are definitely the most frequent message from the HU to the Android box.

I'm not going to personally spend thousands of hours rewriting the MCU firmware from scratch just to get a small amount of improvements.

I do have my own dedicated 3001 on my desk I use for development purposes. I've been pretty busy lately so I haven't had any free time to work on this, but hopefully sometime soon more time will open up.

It's been a while since I've used these tools, but all that top info is info about the file you are going to upload. Looks like you don't have one selected.
[Android Head-Units] TheLoverMan:
is there a way to find what version is running via this tool? Rather than going via hdmi and load up the box?

Also is updating the MCU very important to do or is it just advised? I have not had time to hook the head unit up been too ill. Really want to start to play with this but so many problems with install the drivers :(

If it can all be done via cmd line is there a tutorial or any help with the right order of code to imput?

Cheers :)
[Android Head-Units] Bokomaru:
I doubt that it can discover what version is running, the rockchip tools don't really deal with that layer of software, it's just reading/writing raw images. If you have adb installed and working you could run

adb shell 'getprop ro.rksdk.version'

to see what version of Android it thinks it is.

I recommend sticking with MCU v41, it has been the most stable for me and none of the newer releases have offered anything useful for this model.
[Android Head-Units] TheLoverMan:
I get the below is this because of my driver problems? Is there a boot sequence like hold power for 5 seconds or anything like that.

Really sorry but can not find any of this in the wiki if it is there please do link so i can leave you all alone :)
[Android Head-Units] leonkernan:
The main reason I can think of is better access to the radio module.

Bluetooth is easy, since they implemented it as a pass thru so we already have pretty much direct access to the module. Radio on the other hand is hidden behind the MCU software and so we can't implement things like RDS that the radio does support otherwise.

It would be cool (although not useful for most people) to have a basic UI that can access the Radio and Handsfree Bluetooth without the Android box connected.
[Android Head-Units] Bokomaru:
This isn't a device specific thing, this is a general Android thing. What you are trying to do is run the command 'getprop ro.rksdk.version' on the device. Exactly how I pasted it works fine from a linux base but who knows what windows is doing to it.

Try to run the command without the quotes, or another alternative is to just run 'adb shell', then from within the Android shell run 'getprop ro.rksdk.version' (both of those without quotes)
[Android Head-Units] TheLoverMan:
Thanks for all the help mate, i'll install ubuntu or something tomorrow and do it the right way rather than messing you about. You have given me loads to get going :)

Thanks again

ps

did try the above with the shell was coming back with nothing at all no error or anything. But it's fine ill go with linux tomorrow.

Radio app vs bluetooth problem.

When the radio is playing en you try to make a call , the volume of the bluetooth is much less than volume of the radio ( or any other app the playes music).

So when calling you have to level up the volume a lot to hear what the person is saying and than when you stop calling, the volume of the music app is way to hard. Also sometimes it's happens in reverse order and the the music app is very low and the bluetooth is normal. Has anyone got the same problems?

Got adb sorted in ubuntu server, did adb devices but nothing is showing.

How do you boot the android box into bootloader mode or the equivalent ?
[Android Head-Units] usafle:
If you followed the instructions exactly (BusyBox install - V4A Driver Install) and everything, there should be zero reason why it isn't working.

Double check brother, that's all I can suggest.

If you are running Tuataras ROM wasn't V4a already pre-installed in there? It's been ages since I've messed with his ROM... so I can't recall...
[Android Head-Units] TheLoverMan:
Why did no one point me to the .exe driver install ? Would of saved me a few days of messing about.

So for anyone else again this is the link for the drivers from the wiki

[Android Head-Units] TheLoverMan:
When i have the unit in the car setup, can we use the power menu to power down the unit before you get out of the car (if needed, with the pre installed one)

Or will it just turn back on?
[Android Head-Units] f(x):
The default is 2 hours standby time in XdAuto. You can set how long you want the android box to stay on after power off in the mcu settings.

Bluetooth and Radio both have their own volume controls. The Bluetooth one is the two buttons at bottom right of the Bluetooth app settings page. while the Radio one is the slider in the radio settings page.

You'll have to play with them a little to get a consistent level.

If this is the first time you are running the device, or the ROM, do a factory reset in "Settings". This resets android. It will ask for username and password, and I think, it will connect this way. (Be sure that internet works).

[Android Head-Units] neonshaun:
So my nu3001 is supposed to arrive today, and I've been reading through this thread as much as I can before I install it.

What's the best route to take, latest mcu and xdauto? Is the stock firmware that bad? It sounds like there are still a lot of issues with xdauto, like... not powering off the unit...
[Android Head-Units] leonkernan:
The stock firmware isn't bad, it's just mainly targeted at the Chinese market.

xdauto enables some additional functionality and is a bit more configurable. Stick to mcu 41 and xdauto and you shouldn't have any serious issues. There is no reason to go with a higher mcu at this stage as they just introduce more bugs.

so my nu3001 arrived, and I did the stupidest thing... tried to slide the android module out of the little cradle it comes in. By sliding it out, the plastic prongs ripped the warranty sticker in half :( great. Hopefully it works fine...
[Android Head-Units] rendl:
Obviously if google play does not worki guess you download google services apk on pc then put it to the android box on sd or stick then install it via apk installer app. I did not have to do this though, so only guess.

Now i create bootable SD card and test it. It is good method for testing firmware without flash it on real AB

It is work good, but some slow ( sd card 8 Gb 4 class)

Carpad 3

I received some specs on the Carpad3 models. Based on the specs the biggest differences are 32GB ROM instead of 8GB, all models have 2GB RAM, and as I suspected there is no separate Android box.

There are vehicle specific models that have larger displays (7, 8, 9, and 10.1 inch) but there are also the generic universal models we are used to that are 7" (NR3001-H-H0) and 8" (NR5002-H-H0).

Not sure if it is the device or the remote, but the remote does seem to be upgradeable,

Ahaa, build server. Thought it was for GIT only.

Advised for build is 16GB memory, 64-bit CPU (dual-core or higher) and minimum 30GB for a single build. So it makes more sense for me now (excluding GIT space).

Don't forget to enable ccache.

The GIT will be accesble for everyone? Don't know if your down/upstream is axceptable.

If you like, I'm willing to give you an Admin account on my NAS server. Then you can login via webinterface, terminal via webinterface or direct terminal (need your IP address then). 3TB RAID5 configured (read 200+ Mbit/s and write 120 Mbit/s), internet 180 Mbit/s downstream and 18 Mbit/s upstream, quad-core 2.4 GHz and 4 GB memory. GIT is installed but doing nothing at this moment. Running on Synology software.

You can begin testing this way if you like. I'm still reading the "how to build Android" pages I found on Google.

Lol. Well not single. And you are correct, women, cars and electronics all cost.

Not sure what happened to my possessed unit, but this morning on my commute in, checked Viper4Android and the damn thing is working now.

?!??!???

I didn't touch a thing.

My unit is crazy!!!!
[Android Head-Units] renedis:
Maybe you didn't reboot after first install?

Anyway.. It's working now!
[Android Head-Units] usafle:
I've been working on getting this mod to run since I got the device. I've rebooted a lot.

One thing I noticed, is when my unit shuts down (when I leave the car with the key out), I'll come back later and whatever I had playing at the time I left the car will have gone through a bunch of songs. Like if I leave and it's playing track 1, I'll come back and it will be on track 5.

So maybe my reboots weren't hard reboots, just soft? I don't know, I can't explain why this didn't work until I left the car sitting for two days...
[Android Head-Units] renedis:
Noticed this to. The Android box stays on for 2 hours after the ignition is shutdown/key is out. After that it cuts the power off.

When I found this out, I always pause the music/video's before I take the key out.

It is a good feature that the unit stays on for 2 hours. Most of the time you will be back in the car within the next 2 hours and the unit can provide instant operation so you don't have to wait for boot.
[Android Head-Units] usafle:
I know that was discussed before as a feature. But I had assumed it would stop processing whatever was going on until the car came back on. Odd.

I'm still thinking the reboots aren't real reboots at all.

If I have Wi-Fi on my flight to Arizona today I'll post up some excellent convolers for use with Viper for everyone.
[Android Head-Units] renedis:
Nope, it only shutdowns the screen. It does not put it in a standby mode like android phones.

I also don't think reboots are real reboots.. It simply cuts down the power to the android box.
[Android Head-Units] usafle:
That's why I'm thinking viper now works. After leaving the car for 2 days, it might have actually 100% shut off the unit and rebooted for the driver to take effect.

So for those of us that live in cold climate, be warned, the device draws power for at least a day. If your car battery is old, this might effect your winter morning car starting....
[Android Head-Units] nestortoledo:
i dont know how much energy unit can take for this 2 hours still stay turned.

But will be nice have an option to adjust this standby time.

for example able to select

- instant shutdown

- 30 minutes

- 1 hours

- 1:30 hours

- 2 hours

If you do only long travels instant shutdown will be ok,

Dont know if will be posible toimplement this in the custom rom

I certainly have nowhere near the bandwidth that you do. I also had thought that being able to support a large number of users would be unnecessary. this really is a niche product with a small following. So far it looks like I'm going to be the primary person actively working on it. Only two or three others have expressed interest. So between that and the fact that no one needs to (in fact should be disallowed from doing so) pull the entire 10GB+ tree, all they need to pull is the commits since my initial commit on my current local repo which I would transfer over to the server. My initial commit was the unchanged contents of the tar.gz that we all have access to. So all anyone would need to do is untar that then pull the latest commits into that same directory. If it was feasible I would even say we could sync/mirror my git to yours, such as in this http://experiments.openhood.com/git/2010/04/09/mirror-a-git-repository-for-backup/ . This would be great for an offsite backup. and would additionalyl give git users another place to download from. We could make yours the public git server for download only. so if someone did need to download the whole tree, you'd have the speed to handle it. The devs would commit to my server and then I can run test builds right there.

the primary purpose here would be so that builds and changes can happen quickly on the build server I wish to build. I wanted to run gitlabs on it specifically so that I and the other people working on the build can easily see whats going on with the code tree visually as we make more commits. Additionally we would be able to give access to others in the forum to at least pull the recent commits and overlay them on their own untarred directory if they wish to build themselves. those commits don't add up to much bandwidth and additionally, from my experience there will be very few who will do so. Most people will wait for a precompiled package.

And don't worry, I've had my compiler cache enabled from the first build attempt. ;)
