Hello,

my S2 doesn't boot up from eMMC anymore. I tried to recover eMMC using eflasher but had no luck.

Is there an image file which I could use to dd the whole eMMC back to it's fafctory state?

best regards, vincent.

Hi,

which image are you using? Android, Linux?

I´ve found the solution, might be clumsy but it works for both bootloader and kernel: BOOTLOADER 1) copy your compiled u-boot.bin to the eflasher sd card /android directory as bootloader (no fileextension!) KERNEL 1) transfer new kernel to the board via adb adb shell mount -o remount,rw / &&...

Hi @FATechsupport, I´ve compiled a custom bootloader. For the sake of convenience, I´d like to prepare an eflasher SD card including the custom kernel. The idea is, that once the SD card is inserted it should automatically transfer android to the eMMC storage of the NanoPi S2. Ho to include a custom...

Hi @FATechsupport, I´d like to enable LVDS output on NanoPi S2 Android lollipop. So far I can only find the Linux way of achieving LVDS Output: touch .scmversion make nanopi2_linux_hdmi_defconfig make menuconfig Device Drivers --> Graphics support --> Nexell Graphics --> [ ] LCD [*] LVDS (0) Display...

Dear @FATechsupport, I want to control TFT backlight brightness with PWM signal via Android brightness slider on Nano Pi S2. TFT is connected to LVDS connector of Nano Pi S2. TFT has own LED driver for backlight AND provides a PWM input pin. Three questions: 1) How to enable PWM signal genaration by...

Hi @v8dave, I´ve got a reply from jiameijiang via email: You can refer to the following methods, but we can not guarantee that you can use it. First ,you must clone the latest Andorid5.1 source code , then according to the following steps to modify. 1. enter this path: framework/base/core/res/res/va...

Hi Sidi,

did you make any progress? Currently I am facing the same challenge: controlling a TFT backlight with PWM.

Final result should be integrating the PWM signal into the Android system brightness slider.

@FATechsupport
Any suggestions?

Dear Frendlyarm, is there any way to change the screen orientation (portrait/landscape etc.) in your Android 5.1 system code? I don't want to do it with a thied party app. I want to do it in the source code or any other config file eg. build.prop. I've added ro.sf.hwrotation to build.prop and it had...

Yes, thats where I come to set the bootargs, right? I am connected to the Nano Pi S2 via USB UART bridge. Open the connection via Putty COM4 Looking at the output and stopping the boot process by pressing any button (host pc keyboard in Putty console) within the 3 seconds window. Then I change the b...

Hi, I´ve successfully testet this: https://www.kingoapp.com/root-tutorials/how-to-root-android-5.0-5.1-lollipop-with-root-apk.htm Be careful tu uncheck "install recommended apps" and then you should be good to go. It installs su in /system/xbin/. Tested it with ES File Explorer (Root explo...

Dear friendlyarm, I´m trying to drive a TFT panel (1280x120px) via RGB interface of the NanoPi S2. http://www.naxtechnologies.com/datasheets/TFT/TFT1280120-1-E(11D)v1.1.pdf I`ve modified kernel source code and added the timings for the TFT panel in: /arch/arm/plat-s5p4418/nanopi2/lcds.c and compiled...

Dear Friendlyarm, apparently setenv and saveenv are not working. Once I´ve set the bootargs via UART interface via a serial terminal: setenv bootargs console=ttyAMA0,115200n8 androidboot.console=ttyAMA0 androidboot.serialno=0123456789abcdef initrd=0x49000000,0x100000 lcd=HDMI1080P60 bootdev=2 I type...

Dear Friendlyarm,

I do need to run software which requires root access.

Will you provide a rooted Android 5.1 image eventually?

How to root the device using the existing Android images?
