Power & Source of Big Ideas

Hi for now we only gave the instructions on how to make an Android image. We haven't given the instructions for Debian. If you want information about Debian you may check Debian Jessie's site.
Another open source LINUX Deepin 15 runs on the NanoPi 2.

Hi our NanoPi 2 doesn't have an LVDS interface.
Did you refer to the NanoPi2's LCD interface? If you referred to the LCD interface I would put it this way: if your LCD's connector matches the our LCD interface's Pin specifications yes your LCD can work with our Pi 2
Sorry we don't have a good way to check it. You may have to use an instrument to do it.
Hi you can try these:

Set its min freq:
echo 800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

Set its max freq
echo 800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Hi you can try compiling libcrypt first and then add this library when compiling apache.
Sorry so far we only have this kernel for Android. In the near future we may not work on a new kernel for Android.
FriendlyARM released a high definition 7"LCD with capacitive touch.

Hi we have uploaded two diagrams for NanoPi 2's component positions.
You can go to our wiki : http://wiki.friendlyarm.com/wiki/index.php/NanoPi_2 and search for "NanoPi2-Component-bot" and "NanoPi2-Component-top"
Hi did you do that as "root"? If not please try doing it as root
Hi you can check our wiki: http://wiki.friendlyarm.com/wiki/index.php/NanoPi_2
Please search for "Under Windows" and then you will be able to find a "download link". Click on it and go to the google drive option.
Hi, editting "/etc/hostname" is a way to change the hostname. We did that this way on the NanoPi 2.
One user posted a thread asking about the support for I2S in NanoPi 2. We are sorry the nanoPi2 doesn't support I2S. It doesn't have such an interface or pin.
Hi the SN_USB_AUDIO should be in our kernel. You can search again. I think you can just add that option in the menuconfig and recompile the kernel.
Hi again Today I received 115k resistors. I replaced R452 100k resistor with 115k and still can't boot device. Now I have on my multimeter 1,135V instead 1,059V. Also now board restarts itself after 5sek waiting (have this value from logs). I will check with 120k resistor Hi Krystian could you help...

I can observe the bootup messages but can not control the NanoPi2 from the PC serial terminal.

Just a guess ... should there be a ttySAC0 in /dev?

Thanks



Yes UART0 is "ttyAMA0",

We don't have UART1.

ttyAMA2 is for UART3 and
ttyAMA3 is for UART4
When 2nd boot loads uboot it will read a 512byte-header which contains necessary boot information such as the uboot's size. This 512byte header is very important for correct booting. When users do it via fastboot fastboot will create this header automatically with correct information. If users want ...
Hi This may be caused by your 32 bit OS or your card reader. The "tools/sd_update" is for a 64-bit OS. We added this check "/sys/block/sdb/removeable" in the script in order to prevent users from writing his hard disk accidentally. In your case you may try removing this restricti...

R452 influences VDD_ARM. After that change (from /100k/1% to /115K/1%) the voltage jumps from 1.2V to 1.29V.

One more detail: 1.2V doesn't provide enough power in some transient condition so we change the resistor
Hi I am not quite sure which points you referred to . I would guess you referred to the two points I marked in the attached screenshot. If my guess is correct yes they are for RTC. It is for non-rechargeable 3~6V battery

Hi thank you very much for paying attention to our matrix.

You can check our wiki for the temperature module:

It has detailed information on how to use it. I wish this could help you
Kali Linux released its OS that runs on our NanoPi 2.
Interested users can try it here:

Search for "FriendlyARM"
I would suggest you use our recommended resistor
Hi Krystian, you only need to change R452. In the second picture there is only one resistor marked in red. That is the one you just need to change.
The NanoPi2's CPU adjusts its frequency depending on its load.
Hi the Pi doesn't have this function. The NanoPi 2 Does. The NanoPi 2 adjusts its frequency automatically.
Some users tried Kingston cards and didn't succeed. Sorry we haven't found the root cause for this issue yet.

We suggest you try the cards listed on our wiki:

Thank you very much for choosing our boards and sorry for causing you this trouble. Please check my comments: 1. make sure your power supply is 5V/2A and it is stable 2. could you please help check the resistance of R452 (please check the attached file): is it /100k/1%? If yes could you find a new r...

Some users asked us how they could replace the "FriendlyARM" boot logo with their own.
Actually that logo is in the first (ext4) section of a ready-to-go SD card. You can search for "logo.bmp" and replace that file with your own boot logo.
We added support for NanoPi2's UART in both Debian and Android:

/dev/ttyAMA2 and /dev/ttyAMA3

ttyAMA2 is for UART3 and
ttyAMA3 is for UART4
