Hi, I found nice node module for using BLE on linux: https://github.com/sandeepmistry/noble https://github.com/sandeepmistry/bleno But there is requirements for kernel version which is 3.6 or above. I found that NanoPi2 uses kernel with 3.4 version. It is possible to easily change this kernel(I am n...

Hi again, I don't write here quite long time from my last post. In that time I received new board with fixed resistor. Yesterday I have some time to check if this new board boots correctly. Now for testing I used 64GB SanDisk card with 10Class and Debian image with AP mode (Feb 27). For power supply...

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,
I measure current voltage of VDD_ARM and I have 1,059V so according to datasheet it is too small. I order 200k (for R452) and 180k (for R453) resistors which will give me about 1,266V.

I checked nanopi2 circuit and found that VDD_ARM_AP power signal represents VDDI_ARM on S5P4418 processor. On 87 page of Samsung datasheet we can find that description for VDDI_ARM signal: "1.0V to 1.3V for CPU". According to nanopi2 circuit we can see that VDD_ARM_AP is obtained by MP2143...

Today I tried to use new sd card - SanDisk Ultra 10 class 64GB and also booting failed. While booting I measured VDD_5V and I have 4,86V it is correct value? Samsung chip is very hot In my market I can't find resistor with 115k and 1% tolerance value. I can buy 120k resistor. It will be good resisto...

I checked value of this resistor and my multimeter gives me 50k. But I measured it in board so value can be affected by other elements. Are this two resistors connected in parallel?

Hi, today I received my nanoPi 2 board. I looks cool but I have some problem with booting debian image on it. I download image from Google Drive with support to AP mode. Next I prepare microSD card and write image using OSX system and also tried to do that on Windows. Then connect TV and plug in to ...
