Waxberry Pi3 Rockchip RK3188 Development Board Includes a SATA Port

Development boards based on Rockchip RK3188 are a rarity, and until today, I only knew about Radxa Rock boards. Waxberry, a Chinese based company, already made some development boards such as Waxberry Pi2 based on Rockchip RK3066, and recently they’ve launched Waxberry Pi3 development board powered by Rockchip RK3188 processor, with 1 GB RAM, 8 GB flash, a SATA port, expansion headers and more.

Android L x86 64-bit Developer Preview Emulator Image Released

Several weeks ago Linaro posted instructions to run Android L ARM 64-bit in QEMU which takes some efforts to setup, and at the time lacked OpenGL support (not sure about the status now). Google has now releases their own 64-bit Android L preview image for the x86 emulator, and hopefully they’ll release a 64-bit ARM image and NDK sometimes in the near future, as 64-bit mobile devices are expected for Q1 2015. That means developers can now test the 64-bit version of their apps build for x86 using Google emulator. Java only apps should most probably work without issues, but apps relying on native code (C/C++/assembler) will certainly require a little bit more work. The latest Android NDK (r10b) support 64-bit code, and apps can be built with x86_64 build target, or using APP_ABI=all64 in Application.mk. 64-bit support increases addressable memory space, provides a larger number of registers, and new instruction […]

Linux based MOD Duo Multi-Effects Pedal is Powered by an AllWinner A20 SoM (Crowdfunding)

If you are both a maker and a musician, MOD Duo multipurpose pedal may be a fun “toy” to play with. It’s an embedded computer comprised of a Hi-Fi soundcard (baseboard) powered by the same ITEAD Studio A20-CORE system on module found in ITEAD Studio IBOX, fitted into an enclosure with a pedalboard interface, and two graphics displays. You can create and share your own effects, or download the one made by the community using LV2 sound plugins, an open sound processing standard. A MOD Arduino Shield is also available to create new peripherals. Some technical specifications of the MOD Duo: SoC – AllWinner A20 dual core Cortex A7 processor @ 1GHz (AllWinner A23 is part of stretch goals) Two audio inputs Two audio outputs Stereo headphones output MIDI IN and MIDI OUT Cirrus Audio Codec USB – 1x USB Host for bluetooth, Wifi adapters and MIDI peripherals, 1x USB […]

Creating and Flashing an Android Image from Rockchip RK3288 SDK

Following up on my post explaining how to build Android for RK3288 TV box, I’ve generated a firmware image, and flashed it to Tronsmart Orion R28 Meta TV box to see if it could boot properly. There’s basically no information in the Andoird SDK explaining how to do basic things like building from source, and generating and flashing the resulting image, so I’d like to thanks Linuxium, Droidmote and Naobsd for their various tips. Since I’ve built everything from source, I’m using a Linux machine, but you should be able to create and flash the Android image in Windows using tools in RKTools/windows folder. First let’s copy the required, and freshly built, files to create the firmware:

cp rockdev/Image-rk3288/* RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/Image/
cp RKTools/rk3288-3.10-uboot-data1G.parameter.txt RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/parameter
cp RKTools/bootloader/uboot-emmc/RK3288Loader_uboot_Apr212014_134842.bin RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/
cd RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/

cp rockdev/Image-rk3288/* RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/Image/

cp RKTools/rk3288-3.10-uboot-data1G.parameter.txt RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/parameter

cp RKTools/bootloader/uboot-emmc/RK3288Loader_uboot_Apr212014_134842.bin RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/

cd RKTools/linux/Linux_Upgrade_Tool_v1.2/rockdev/

We’ll also need to edit package-file follows (I only had to change the bootloader field):

# NAME Relative path
#
#HWDEF HWDEF
package-file package-file
bootloader RK3288Loader_uboot_Apr212014_134842.bin
parameter parameter
misc Image/misc.img
kernel Image/kernel.img
boot Image/boot.img
recovery Image/recovery.img
system Image/system.img
backup RESERVED
#update-script update-script
#recover-script recover-script

# NAME Relative path

#HWDEF HWDEF

package-file package-file

bootloader RK3288Loader_uboot_Apr212014_134842.bin

parameter parameter

misc Image/misc.img

kernel Image/kernel.img

boot Image/boot.img

recovery Image/recovery.img

system Image/system.img

backup RESERVED

#update-script update-script

#recover-script recover-script

And now create the firmware file:

./mkupdate
start to make update.img...

How to Build Android 4.4 for Rockchip RK3288 Devices (Tronsmart Orion R28)

After blowing up my ATX power supply, and learning such things as “FULL” power supplies do exists, I finally managed to build Android for Tronsmart Orion R28 using the provided SDK. I haven’t tried to load it on the device yet, but the build could complete successfully after following the steps below in Ubuntu 14.04. The SDK is probably not specific to one device, so it might just also work on other RK3288 TV boxes and tablets. First download Android 4.4 SDK for RK3288, or use the one in the micro SD card provided with the Beta version of R28 Pro and Meta. Install some dependencies:

sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.8-dev \
squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev pngcrush schedtool libxml2 \
libxml2-utils xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev \
lib32readline-gplv2-dev gcc-multilib libswitch-perl gcc-arm-linux-gnueabi lzop libncurses5-dev \
libssl1.0.0 libssl-dev

sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.8-dev \

squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev pngcrush schedtool libxml2 \

libxml2-utils xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev \

lib32readline-gplv2-dev gcc-multilib libswitch-perl gcc-arm-linux-gnueabi lzop libncurses5-dev \

libssl1.0.0 libssl-dev

Extract the SDK:

tar xvf Orion_R28_SDK_doc.tar.gz

1	tar xvf Orion_R28_SDK_doc.tar.gz

And build the kernel first: Enter the kernel directory:

cd RK3288_R-BOX_ANDROID4.4.2-SDK_V1.0.0/kernel/

1	cd RK3288_R-BOX_ANDROID4.4.2-SDK_V1.0.0/kernel/

Change arch/arm/boot/dts/Makefile to use RK3288 device tree file instead of an RK3188 (may not be needed, but the build failed for me without that change…):

dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3288-box.dtb

1	dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3288-box.dtb

It’s also quite […]

Tronsmart Orion R28 Meta RK3288 TV Box Unboxing

GeekBuying sent me one of their Tronsmart Orion R28 Meta (Beta) Android TV boxes powered by Rockchip RK3288 SoC. This model comes with 2GB DDR3, 16 eMMC, and 802.11 b/g/n/ac Wi-Fi. R28 Mega is the mid-range model, and there are two others models R28 Pro (entre-level) and R28 Telos (premium). I’ve already listed specifications for the three Tronsmart Orion R28 models. Today, I’ll show some picture of the device, and the board to find out more about the design of the product. Before reviewing the product in another post, I’ll probably build the image using the provided Android 4.4 SDK (provided I can download it), and perform the full review next week with the resulting firmware. Tronsmart Orion Meta R28 Unboxing I’ve received the parcel via DHL within 2 days. The same package will be used for all three models, but you’ll have a sticker on the side for Pro, […]
