U-boot, Linux Kernel, and Android Patches for Freescale i.MX6 HDMI TV Dongles

We can now get some quad core Android mini PCs (e.g. Hi802, GK802) featuring Freescale i.MX6Q processor, Freescale has released full documentation and source code its development platforms, Hi802 / GK802 HDMI TV dongles are easily hackable, and there’s even an Ubuntu image for the devices. So it looks pretty good ,right? Well almost.. there are some patches and config for GK802 that have not been released by Richtechie, so we can’t modify the bootloader and Linux kernel. But this may change, as ARMTvTech forum user hste noticed some Freescale i.MX6 HDMI dongle patches om IMX Community website. Even though I’m not sure those are fully compatible with Hi802 / GK802, this could be a starting point. Today, I’ll provide the instructions to build u-boot, the linux kernel and Android ICS with those patches in a machine running Linux 12.04 64-bit. Patch Sets Descriptions There are two set of patches that […]

Linaro 13.01 Release with Linux Kernel 3.8 and Android 4.2.1

Linaro has just announced release 13.01 which includes Linux Kernel 3.8-rc4 and Android 4.2.1. A lot of work seems to have gone in Arndale board and OpenEmbedded ARMv8. It’s the first time an Ubuntu image is released for Arndale Cortex A15 development board. One the kernel side some Android upstreaming work has been done, as well as some fixes for eMMC, and code for ST Ericsson Novathor 8500 SoC has been reorganized. Version 14 of the big.LITTLE MP (Multi Processing) has been released. The LEG has done further work on Linaro UEFI and GRUB. Here are the highlights of this release: Android Platform Work The first step of the android-build front-end update for new build program has been landed. Origen and Versatile Express manifests have been consolidated into a single manifest. linaro-android-tools were developed to improve development time for kernel developers. See Kernel Update Tools for details. The android-build scripts […]

ARM MCU Development in Linux with Energy Micro’s Simplicity Studio, Eclipse, and CodeSourcery Toolchain

Quite a few months ago, I received an Energy Micro EFM32 Tiny Gecko Starter Kit, but I haven’t done much with it. But recently I saw a tweet from EnergyMicro about Simplicity Studio supports for Ubuntu, and I know it can be problematic to find proper tools for ARM MCU development in Linux, so I decided to give it a try. The first part is about Simplicity Studio, and energyAwareTools which are specific to Energy Micro, but the second part deals with setting up Eclipse and CodeSourcery ARM toolchain for MCU development which should be reusable for other MCUs from vendors such as Texas Instruments, NXP and STMicro. I’ve used a PC running Ubuntu 12.04 64-bit with the instructions below. Installing Simplicity Studio and energyAwareTools in Ubuntu Simplicity Studio is part of the 4 steps of the getting started guide with EFM32 MCUs. It has been available for Linux for […]

Google Drive Integration in Ubuntu with Insync

There are several ways to get cloud storage in Ubuntu, and access it from Nautilus with products such as Ubuntu One or Dropbox. But if you’re running out of space with those services, you may also consider using your Google Drive account with Insync (Beta). Here’s how I’ve installed the latest version (0.9.35) in Ubuntu 12.04 64-bit:

wget http://s.insynchq.com/builds/insync-beta-ubuntu_0.9.35_amd64.deb
sudo dpkg -i insync-beta-ubuntu_0.9.35_amd64.deb
sudo apt-get install xdotool python-nautilus
sudo apt-get install -f

wget http://s.insynchq.com/builds/insync-beta-ubuntu_0.9.35_amd64.deb

sudo dpkg -i insync-beta-ubuntu_0.9.35_amd64.deb

sudo apt-get install xdotool python-nautilus

sudo apt-get install -f

At this point, reboot or restart nautilus (“nautilus -q” in a terminal window). I’ve then used Dash to launch Insynq. This just launched insync website, and allowed me to register my Google Drive account. You should now see Insynq shows up in your home folder. It may be a good idea to add it as a bookmark as well. At this point, you should realize something is not working that well since Insync does not show in the contextual menu. That’s because you need to run insync manually in a terminal window, […]

Raspberry Pi Now Has Experimental Support for VP6, VP8, MJPEG and Ogg Theora Video Codecs

The guys working on the Raspberry Pi (mainly dom) have added preliminary support for VP6, VP8, MJPEG, and Ogg Theora free video codecs, as well as Ogg Vorbis audio codec. Unlike H.264, MPEG-2 and VC1, those are not handled by the hardware video decoder in Broadcom BCM2835 processor, but are accelerated by the Videocore GPU. This means that only SD (and possibly 720p) videos are supported for those codecs. The best way to get support is probably to patiently wait for the Raspberry Pi foundation to release a new Raspbian image, but in case you couldn’t possibly wait, here are the steps to follow: Download and run Hexxeh’s rpi-update script in the Raspberry Pi in order to get the very latest build:

wget https://github.com/Hexxeh/rpi-update/raw/master/rpi-update
chmod 755 rpi-update
sudo ./rpi-update

wget https://github.com/Hexxeh/rpi-update/raw/master/rpi-update

chmod 755 rpi-update

sudo ./rpi-update

Add the following two lines to /boot/config.txt:

start_file=start_x.elf
fixup_file=fixup_x.elf

1 2	start_file=start_x.elf fixup_file=fixup_x.elf

Reboot the Raspberry Pi The GPU firmware is now updated, but you still need the latest version of omxplayer. […]

How to Access the Serial Console in HI802 / GK802 mini PC

One of the advantage of HiAPad Hi802 (aka Zealz GK802) is that it provides access to UART and I2C pins via through holes on the board. UART4 Tx and Rx pins give you access to the serial console which is a must for bootloader (U-boot), and kernel development or for debugging. The first thing is the open the casing and locate the debug pins on the board. The very best way is probably to solder a pin header, but since I don’t have header, nor soldering iron, I’ve done it the “MacGyver” way with 3 wires connected to TxD, RxD and GND, and some sticky tape. You can now insert the other side of the wires into your USB to TLL debug board (GND <-> GND, Tx <-> Rx, and Rx <-> Tx), and connect it to your Windows or Linux PC. The serial board should be recognized as a […]
