Power & Source of Big Ideas

You can do this but you will have to use a custom kernel to set the timing of the display. If you want touch, you'll also need to add a driver for this if the touch controller is not one supported by the kernel. You'll also need to know the LVDS bit allocation applied to each channel for your chosen...
The mating connector is a JST part number GHR-03V-S and stocked by Digikey along with crimp pins although I would suggest getting the jumper leads and using those by soldering onto existing wires as the tooling for the crimps is likely to be expensive. https://www.digikey.com/product-detail/en/jst-s...
Never understood why so many boards are not fitted with an external POWER button connector. It makes them very difficult to power on unless you have access to the power button that is fitted to the board, and not something that is ideal at times. I want to use the T4 in a sealed enclosure so I need ...
I've gotten to work but it won't send or receive multi-part message for now.
Where did you connect the external battery to?
Thanks Jerryn I updated the kernel recently and it included a new fake battery driver for the NanoPC so I am thinking I could use this as a base to control the system. Using a battery monitor IC with I2C I could read the real value and feed that back into the Android OS. I am still trying to upload ...
FriendlyArm provide a driver for this but you can also create your own with a JNI. Search for Android I2C as there is some sample code out there for this. The latest Android Studio can build and debug native code.
You are likely going to have to build your own Android OS and include suitable drivers for your GPS module.
As we have no way to connect an external battery to the PMIC on the NanoPC T3 Plus, I was considering adding a suitable battery that would supply 5V at up to 3A to the 5V input on the GPIO connector and adding an I2C based charging IC that I could read the battery state from. Has anyone looked at th...
Looks good. Just double check the pin for + when you get them. Easy enough to swap them but most likely will be correct.
You need something like this with the connector. I use similar with the NANOPC T3 Plus

Have a look at the WiringNP library to see how they handle this.

Those will be in the Linux kernel and likely require a rebuild.

For Android boot you only need to change the bootanimation.zip file to add your own.
Do a search on S430 in the source as this is one of the LCD displays and then you can see how they handle the different versions. FA uses a 1-wire bus to read the type of display. This is all open source so you should be able to modify the bootloader etc to do this for your own display.
Good stuff. I should update my blog and post how I created a custom build for the NanoPC T3 Plus and how I added GSM support and also how to add custom ready built APK files to the build. Also how to set the display in Landscape although I still have silly issue with the boot animation being squashe...
Try typing lunch on its own and you will get a list of boards you can build. Select the one you want and the try the build again. Make sure the output from this shows the correct build then you should be good to go. I have added mobile networking via GSM and a few other things but can't find a suita...
If you have the M2A module then WiFi should be working out of the box as this is built into the module. For LTE you need to connect a suitable modem via USB and then build phone support into the OS. You're best way to do this is to get the Android source code and then make the changes to include thi...
It's marked as TODO so not likely to have been completed and tested.
I am overseas just now but I will post a link to the source for you and details of how to change it on my return next week.
Why not just use the FriendlyArm 10.1" LCD as it will just work out of the box? If you go with this one, you will need to make an adapter and handle the backlight and the fact that the LVDS from the NanoPC is 24 bit but you panel is only 18bit means you will have a bit of work with register pro...
What chipset does the USB device have?

It's possible that the driver is not included in the OS build.
I have Android running on a T3 Plus and after some time connected via USB, it loses connection and then appears in Device Manager saying that it failed Device Descriptor Request. It now does this until I reboot the PC. Swapping USB ports does not work. Tried 3 different cables. Same thing. Has anyon...
Which OS as I rebuilt the Android source to swap the display to landscape on boot up. Works with the 4.3 and 7.0 displays that I have.

If I can find somewhere to host the source I'll do so but at 10GB I've been unable to find anything suitable so far.
Not required. I rebuild the kernel and Android OS from source so now it boots in landscape mode.

I also added GSM modem support so now also have data coverage outside WiFi areas.
OK. I have finally tracked this down and fixed it so that it can work but the issue that causes this is still in the code. The fault is caused when NetworkMonitor handles the CAPTIVE_PORTAL_SERVER using the property ro.net.captive_server in setprop. mServer = Settings.Global.getString(mContext.getCo...
Are you still working on this?

I have a partial working RIL build for the NanoPC T3 Plus with Android 5.1 and include the SIMCOM RIL and I can send and receive SMS but PPP crashes com.android.phone after it connects. Trying to get some help with this.
Probably a bit late. None of the recent Android builds from FriendlyArm include any support for LTE modems. There are a number of USB options but you would need to build a custom OS. I've done this but com.android.phone crashes when I get a PPP connection and not tracked this down yet. Looks like a ...
I have managed to create a custom Android build with GPRS support using a SIMCOM RIL and SIM5320E modem module. It can send and receive SMS but it crashes com.android.phone when it connects to PPP and I have been unable to track down the reason for this. If anyone is willing to help I have permissio...
I have a GPRS modem and built a custom OS with the RIL and I can get a signal display and I can send and receive SMS. What I can't get it GPRS data. I get a PPP error and it is due to a policy issue as I see the following in the logcat output. [ 881.924000] avc: granted { set } for property=net.gprs...
I just logged into the website to order some more NanoPC-T3 boards and I find that they are no longer available. I've just design and made a number of expensive boards to use with this board. The new T3(2GB) is a completely different footprint. Is the T2 compatible with the same Android build as for...
If you are running Linux why not just plug it in and see if it works?

It will or it won't and being USB it won't do any damage to your board if not.
Yes, that is the idea behind having a battery for this purpose.
There is a place to solder a 2 pin header to the board and then you can plug in a battery. The pitch is 2.54mm and it's behind the USB and Ethernet ports next the I2S header. On my boards it's unsoldered.
I wonder if this is to do with policies as I see the same issue on my T3 and M3 boards running Android 5.1 when trying to use ttyUSB2 with a modem plugged in. Try this from either ADB shell or from the UART as root (type su first) setenforce=0 That should disable the policies until the next boot. Se...
I have received a RIL from SIMCOM and I am using a SIM5320E module and I have partial phone integration now. I can see the phone settings and icons. I still have some errors to resolve. I can send and receive SMS but I still see NO SIM CARD being displayed and there is no GPRS support. I am in touch...
I actually found it and have been able to build it. For anyone else looking for this, it's on the Wiki page for the NanoPC-T3 and you just have to follow the instruction to download this onto your machine and then configure and build. It requires a bit of work to use it as the build is bigger than t...
Look at the GPIO connector. The pins are marked on that. Pins 29 and 30. Be aware that using a long ribbon cable will cause a voltage drop at the T3. You may read 5V at your input but it can be as low as 4.7 at the T3 due to voltage drop and it does not like this. I saw this with an M3 I powered fro...
Where can I find the Linux kernel for Android 5.1 I only have the source for Android and a binary for the uimage on the SD card. I can build the Android source but I also need to add some features to the kernel so I need to build this from source too. I've check on GITHUB and found nothing for the S...
I'd prefer not to use that command as it opens up a can of worms. I've noticed that the Samsung rild.te fileI found online for 5.1 has tmpfs settings and I have tried these and still get avc denied. Even tried to set chown on ttyUSB2 as radio:radio and still nothing. If i could get the right policy ...
I have almost gotten GPRS modem support to work. At least as far as seeing AT commands from it. Still need to get the correct RIL for the modem but progress has been made to show a phone and SMS messaging etc. I'll post this on my blog later when the final system works. I have an issue with policies...
Have you sent a direct email to them about this?

I've tried a few times and got no reply either. Poor customer service if you ask me. :(
BUMP.

I've rebuilt the OS to include the Phone XML files but it still does not recognise the modem.

Has anyone been able to include GSM support into any of the Android 5.1 builds? It is critical that I can get data communications support with this Android build.
Did you every find out how to do this?

The website for the HD702 LCD display shows this is a landscape display but I only seem to have a portrait display. I need to use this as landscape only.
No, what is the actual cd/m2 of the 4.3" LCD

200, 300 cd/m2 etc?
I am getting errors when trying to repo sync the source code. This is the output from the console. Has anyone been able to successfully clone the repo? curl: (22) The requested URL returned error: 404 Not Found Server does not provide clone.bundle; ignoring. 19 168M 19 31.9M 0 0 281k 0 0:10:12 0:01:...
Does anyone know the corresponding connector part number for the RTC connector on the T3 board?
I can confirm that this works. I need the USB port for debugging Android so I power the board from the GPIO pins. Make sure your cable is heavy enough to carry the 1amp or so of current that it draws on power up (with LCD 4.3) otherwise you will get a low voltage at the input and the board will shut...

hi,
We want to control a button connected to EINT-8 or EINT-15. we couldnt do that.


Are you trying to use interrupts or just polling for the input changes?

For interrupts, you need to be at the kernel level.
Does anyone have the brightness (cd/m2) for the LCD panels?

There is nothing listed on the website. I am interested in the HD702 but need to know it's brightness value?

[EDIT] The PDF on the wiki shows 7,500 but that is impossible.
When you copied the file to the device did you make it executable with "chmod +x filename" ?
