Is there anyway to run this board using armbian?

[zador.blood.stained 762]

No, there are no supported Armbian images for this board, and, as I said earlier in this thread, it's higly unlikely that Armbian will support it.

I am confused, did you give up cleaning the code? I was waiting for you and parrotgeek1 to do the hard work and then jump in to try to build the image.

I don't have the board but was just readying the environment when i get one.

Can you please clarify your roadmap on this device?

[hojnikb 17]

there seem to be user generated armbian images on the orange pi facebook group.

So, the WiP can actually build a working Image?

No, but I don't want to waste too much time on this board. I would prefer to see that there are other people who are willing to do time consuming tasks, otherwise I may as well delete the Armbian config and pretend it was never added in the first place.

Current issues:

• When booting from SD, NAND is not initialized for some reason. May require dumping and disassembling the BROM
• Audio driver is a mess and hangs the system for an unknown reason
• Existing documentation is not enough to fix existing issues without trial and error, and since the board has no Ethernet and no mode similar to FEL boot (at least not a good documented one), it means burning through SD cards
• BootROM is quite picky on SD cards, so you'll need to have a good one for working with this board
• Whole system design is kind of questionable. Different kernel drivers talk to the modem for a variety of reasons, and existing kernel pretty much relies on properly initialized modem. This definitely won't help with the kernel cleanup

There is an "Armbian image" on the Orange Pi download page too, which I'm definitely not happy about

Preferred roadmap:

• Throw away drivers that can't be tested: camera, display, GPU, VPU, gouda, ...
• Port all that is left on top of a clean 3.10.x branch (and not an Android fork). Current Android kernel is a minefield, enabling/disabling kernel config options (even not HW related ones) has a good chance of resulting in a compilation error

What will be done on practice? Who knows...

Yes, "working". There are missing features (i.e. namespaces) and disabled HW drivers (pretty much all multimedia). And ideally you need to dump calibration data from NAND and set a permanent MAC address using a kernel module parameter.

[@lex 120]

Good to hear there are others working on it also... Thanks.

At least it's not dead already (and we know which image sensor Xunlong chose): https://github.com/OrangePiLibra/OrangePi_Camera

 

Just a small comment, looking at the manual the CSI pins looks like they are not reversed as usually on all OPIs which is a good thing, if that is correct no way to use the OPI camera, but there is ov5642 driver that may be in good shape.

If they release the LCD with the attached camera as in manual it will be of good use but is only 0.3 MP.

So which camera modules would fit there? Those from FriendlyELEC?

Attached is the FPC pinout for analysis.

 

 

 

From the manual (CSI connector):

 

Your link just confirm the sensor is GC0309 (the one attached to the LCD panel) and that is 0.3 MP sensor.

If the metallic contacts face down, OV5640 seems to fit but there is no OV5640 driver in the kernel only OV5642.

 

But i am not sure the connector representation is at the board side or at the LCD side (that would means it needs an extension/conversion of signals), i leave this review to the HW guys.

But, again, I would say that camera stuff is a really low priority task right now

I'm not sure where the metallic contacts are in the camera connector, but if you look at the board photos you can see pin numbering - pin 1 is near the antenna connector and pin 24 is near the GPIO header.

Add this to the confusion:

Small progress: factory calibration data can be extracted from NAND using NAND update tool (Export Fact button)

I've the board here since some weeks, if you need more testers...

Sorry, we need more developers to clean up the kernel sources to even have anything worth testing.

Hello,

today I've got my 2g-IOT. I have found that it uses 40-pin LCD connector. Which LCD is suitable for this?

[martinayotte 618]

The 40-pin connector isn't dedicated to LCD, it provides different GPIO/UART/I2C.

It is up to you to attach a LCD properly suing some of those pins.

Also, it is depending of your LCD requirement : is it simply to display some things from python scripts, or you wish to have full Linux display ?

(For the full Linux display, I would bet that drivers will be difficult to obtain for this board)

Display connector (ZIF or whatever this type is called) is 40 pin too. It has SPI, I2C, power (including power for LED backlight) and some kind of paralled LCD interface.

AFAIK there are no compatible premade displays for this pinout, but I heard that Xunlong may start to sell compatible displays (assuming they can make the software work well enough)

Is there any way to run the DHT22 sensor with this board? I have used the adafruit libraries and they do not work, it gives the following error: Bus error

Hi bro:

 

  I'm porting AT command to OrangePi 2G-IOT, but it's different, has a lot of problem on modem,

 On Android demo code, program utilizes /dev/ttyMux0 or /dev/ttyMux1 to exchange AT command,

 but on Linux, I can't find /dev/ttyMux0 or /dev/ttyMux1.

 

 I'm serach source code that registers /dev/ttyMux. but.... on /kernel/drivers/tty/serial/  , no API or code segment to achive it..

 So, I want to know how to register /dev/ttyMux...

 

Send message utilize /dev/socket on Android, but the same way... no /dev/socked on Linux....

This is github of OrangePi 2G-IOT:  https://github.com/orangepi-xunlong/OrangePi

 

[martinayotte 618]

On Linux, it is probably connected to /dev/ttySx, where x can be from 1 to 7.

[zador.blood.stained 762]

On the available kernel modem is accessible via /dev/modem0 and /dev/modem1

[Lope 5]

I originally got a bit excited when I saw this board because I've been wanting to do an IOT project for a while.

But the lack of a working linux image and working 2G Modem environment keeps me away from working with it.

I'm a software developer but I've not delved into Linux yet.

Also the sound of burning through microSD cards because there's no FEL or whatever is very offputting also. It means making small changes requires manual time wasting of swapping cards.

On that note I once saw someone made a microSD emulator for RbPi development. But they never became popular.

There are microSD extension cables, and it should be possible to hack one up between a embedded board and a USB microSD card reader with some digital switches or relays inbetween.

 

@tkaiser thanks for sharing regarding the 2G shutdown. That's scary. I had no idea.

I guess 2G will still be an option in developing countries for a while.

Sorry to hijack this post but I just got my 2G-IOT and I CAN NOT FIGURE OUT how to get it to boot off an SD card! It just boots the android from nand but I can't access anything becuase the ADB is disabled. HOw did you boot from sd?

[Melanrz 23]

change pin position near wifi antenna 

[hojnikb 17]

Any tips on how to connect serial ?

I tried connecting like it's labeled on the board, but i'm getting a bunch of garbage in putty. Currently booting from sd card.

 

What serial settings should i use ?

As noted previously in this thread, default baud rate for the BootROM, Andriod images and experimental Armbian images is 921600. Xunlong Linux image uses 115200 AFAIK, but you'll get some garbage from BootROM and u-boot before kernel switches to 115200.

Thank you, this did the trick !

This should be stickied somewhere

 

Now, if someone would figure out how to flash "armbian" image to nand (and strip it to fit nand).
