Ok, quick update:
I got bored, so I started hacking at the Android side. It appears to be very similar to the TI OMAP35xx hardware used in the BeagleBoard. Android is not designed to run natively on this hardware, so it is emulated in qemu with something called Goldfish.
I managed to figure out how to extract the ubi.img file, edit the contents, and rebuild it to something flashable. (currently running my own "custom rom" right now)
I also have root. Working on the force close issue right now. It reared its ugly head ONE REBOOT after first boot, after installing Titanium Backup (root). I'm assuming it has to do with having so little memory to work with on these devices. (128mb I think?)
I plan to release a slightly tweaked version of Dynavin's last release, with out 3g (I don't use it, and I'm assuming most of us here don't, so it's a pointless kernel module to load) and with a bunch of the preloaded apps either removed or updated. It will also be rooted, or at very least root-ready.

Little start to the information -
How to format ANY SD card so the Android side will boot it and load the firmware off it

Must be FAT (otherwise known as FAT16), and set as active. This means no more than 4gb. (you can use larger, but you will have to reformat after to get the rest of your space back)
I used EaseUS Partition Manager to do this. It's free, and is less pissy than Window's disk management, and easier to use than DISKPART.
All you have to do is delete the partition on your SD card (helps to have a dedicated reader here, most phones probably won't work for this), create a new primary FAT(16) partition, and set it to active. Apply changes, wait for it to sync with the OS. Then just load the update files like normal.

From what I've heard, and what I have experienced over the last several hours, it is VERY hard to brick the Android side. (granted, all I've messed with is ubi.img)

Jeff just sent me the magical app that does all this, and I would recommend just doing it the way I just explained if you know anything about partitioning, or are willing to risk messing up an SD card. It is pretty hard to really mess one up though. 98% of the time you can reformat the SD card back to what it should be using a lower level partition manager like DISKPART or EaseUS. PM me if you really b0rk one, and I'll try to help.
Anyways, the reason I suggest using EaseUS is because I'm not a huge fan of using programs that I can't understand due to it all being in Chinese.

Regarding further development:
I would love to get AOSP Gingerbread working on this thing, but it may be out of my knowledge area, and given I only have time on weekends to work on this, I may never get around to it, much less release a working 2.3 ROM for the Dynavin. If anyone here knows anything about Android development and would like to help, PM me. I'll need it.
Other things I'd like to try to do is get some sort of Bluetooth adapter working so we can use Torque. This may also never happen though, since Torque is a HUGE CPU and RAM hog. My HTC Desire died a little while back, so now I have a low end Samsung Acclaim and Torque runs like sh1t on it. The Dynavin is even lower end hardware than the Acclaim, so Torque may be an impossibility for us.


Big Bold Disclaimer: If you don't easily, fully understand what I am talking about in this post, you are best off not doing or following any of it. I am not responsible for anything bad happening, such as bricked SD cards, Dynavins, things starting on fire or going bump in the night. You have been warned.

Nice work Jim. And for what he has in RED above. Ive flashed countless android units, never bricked one, never seen a bricked unit before, so if they start showing up....I will know why, and we will not be responsible.

End disclaimer.

So proceed at your own risk.

It has been my experience that this unit is very buggy at initial start up or at least till the internal battery charges up thourghly so try and have some patience. When I first installed mine it was so buggy that I caught my self laughing at times. Way beyond frustration.
I've had it installed for about a week now and finally worked out all the kinks. Got the Bluetooth dongle to work on the droid side, installed a Bluetooth keyboard, got audio out of all four speakers on the android side (thanks Jeff), got the unit to connect to my android phone hot spot consistently and reliably, got all my apps installed and working (google navigation and pandora are kick ass) and I got a 32gig micro sd card to work perfectly on the droid side so all my music, pics and select movies work great. I never use the radio side of the unit because the android side has every thing an techno nerd would want.

Big props to Jeff and Petrut for all your hard work!

P.S., I think the problem with the GPS grabbing a satellite signal is a firmware issue. I dont think it has anything to do with antenna placement cause ive tried them all. Sometimes it grabs a signal right away and the next time it takes 45 min to grab one and it's totally random. You can be parked in the exact same place every time with the antenna on the dash with a clear view of the sky and still not get a signal. Bury the antenna in the dash and the next time you start the car it grabs a signal right away. Hopefully Dynavin has been experiencing the same issue and will release a patch with the next firmware release. Crossing fingers!

The unit I just purchased from Jeff has 256m of ram, a 600 MHz processor and will support up to a 64gig sd card using fat32 as a file structure. It's working fine so far and I've got the sd card almost fully loaded with music and movies. Your right about it not being a powerhouse though. It's specked at about half what my Samsung infuse is with its 1200 MHz processor and 512m of ram and I can hold that in my hand......

in other words, the touch screen is unresponsive to the android side, but totally works on the dynavin windowsCE side.

The way Dynavin has this loading firmware has absolutely nothing to do with the way you load firmware on the vast majority of Android devices. XDA isn't of much help here.

There is no internal battery, at least not in v5...
What Bluetooth dongle? You are the first person i've heard that has bluetooth working on the Android side. How are you using bluetooth AND wifi on the Android side?
I was under the understanding that v6 just updated the radio side, and didn't do much with the Android side...
The GPS problem was fixed with the latest firmware release last month...

Have you noticed that the android side is running on 500 mhz instead off 600? the procesor is an arm V7 capable of maximum 720 mhz but it's fixed to 500mhz. If you want to make bluetooth work on the android side , take a hub usb , plus in usb wireless and the bluetooth , however i don't think that the will work simultaneously. The catch is simple , we have to find a bluetooth receiver on the market with similar chipset used on first android phones or something that uses native drivers. if we found that , we have the solution for obd torque. I still work on this and i will keep with updates. best regards from romania.

I hear that dynavin want to release a firmware update for the v6 android , is that true? because we need it.

Yeah, I actually just noticed that a couple hours ago. I tried to use SetCPU to overclock it then realized it's running inside an emulator, so SetCPU does zilch. If we want to overclock it, we'll have to figure out how to set the clock speed outside the emulator.

As for bluetooth, I have yet to get a USB hub to work properly, with a usb drive and the wireless stick for example. PM me if you find any bluetooth adapters that work, or have .ko's that I can integrate in to try. Otherwise, I should be able to inject any drivers into the ROM to make any device work, the trick is finding the driver.
My current driver project is getting rtl8187 wireless chipsets working so I can use the far more common Realtek based wireless cards with it, with the added benefit of being able to use ultra high power Alfa usb wifi adapters. No luck so far.

I do have scaling fixed though. (something I asked Dynavin for many months ago) The default is 240 and I changed it to 192 so we can fit more stuff on the screen and buttons/text/the status bar/icons are not massive anymore.

I am taking requests and beta testers
Make sure you read my big bold disclaimer up above first.
I'm taking requests for stuff to include/exclude/fix in the current stock ROM. No "add a driver for this device" unless you have the .ko file for me to include.
I am already removing anything and everything to do with the Phone side of Android. Seems kinda pointless on this unit. I'm also removing the Calendar.
I'm also planning on removing 3g support. I don't have a modem for it, and I bet most everyone else doesn't either.

If you want to be a beta tester, just sent me a PM. You MUST have a good understanding of Android and what you are doing. If you have never rooted an Android phone before, I'd stay away.

Any betas I release will be functionality tested on my Dynavin, and if they don't blow up in the first 10-20 minutes, I usually call it good and continue on. I have v0.03 ready right now for anyone who wants root on their Dynavin without waiting. I would consider it pretty stable. I got one force close in roughly 8 flashes that went away after the next boot. All that has been changed on this ROM is the adding of su, busybox, and Superuser. It is not rooted out of the box, but fairly easy to do, at which point you can run *most* root-requiring apps.

I plan to start a new thread for all of this sometime tonight since most people here are probably not interested in this.

Got root, overclock will take awhile since it will have to happen outside Android, and deal directly with the OMAP35xx processor.

To be honest, the CPU is actually quite fast for 500Mhz. I tested it with Quadrant today and the CPU benches about as well as the Nexus, but Memory is kinda slow. I'll try to get a screenshot up sometime.

Is anyone here an Android developer? I understand the theory behind everything, but I don't fully understand the code if I have to do any recompiling or cross compiling.

i'm in the same boat as you. i can cross compile but don't full understand the code either :/

DOES ANYONE KNOW WHY THE TOUCHSCREEN ON THE ANDROID SIDE OF MY UNIT IS UNRESPONSIVE?!

The overclock will not work because even in stock mode , the unit is heating preety much when you use it...so be careful. I'm not an advanced user in android but i learn quick , if you search/need help also pm me , i will ofer you all my support.

Ideas for your custom rom : Try to find if this board has an extra usb plug on the board [ like the v5 ] , because it's a little easy after that. You can use it like an external storage device. Also i recomend everyone to buy a decent memory card [ class 10 ]. I already search for an android developer.

Loler : the touchscreen is unresponsive on the android side , when you plug something in the front usb. I have the same problem too

If you want to make bluetooth work on the android side , take a hub usb , plus in usb wireless and the bluetooth , however i don't think that the will work simultaneously. The catch is simple , we have to find a bluetooth receiver on the market with similar chipset used on first android phones or something that uses native drivers. if we found that , we have the solution for obd torque. I still work on this and i will keep with updates. best regards from romania.

I hear that dynavin want to release a firmware update for the v6 android , is that true? because we need it.
I just bought 2 powered USB hubs from comp USA plugged them in but didn't power them off the included transformers. Just using them in passive mode. The Navi side works well with the hub in passive mode and is powering a Belkin N draft card and a small Bluetooth dongle that I had laying around in the garage, both at the same time. I'll check the manufacturer tomorrow and post it for you guys. Both devices loaded right away and configured with ease. Got lucky I guess. As I said before, I loaded the drivers for a Bluetooth mini keyboard and it works. It was a configuration challenge but it did work after an hour of messing around with different versions of the software.

As for the radio side, it doesn't like the USB hub in passive mode at all. It won't power any device no matter how small the power requirements are. I haven't tried it with the transformer plugged in yet so I will be testing that later.

You say that the unit can power the wireless and bluetooth at the same time? that is great , but what bluetooth receiver do you used?
