How to Modify HDMI Output Parameters in Linux for ODROID-XU3 (Lite) Development Board

Good news, I’ve finally managed to make HDMI output in my ODROID-XU3 Lite development board work with the Ubuntu image after some more tweaking. So ODROID XU3 Lite Ubuntu review is coming in the next few days. But first, I’ll explain the few steps I went through, in case others experience a similar issue. I downloaded, extracted, and flashed the latest Ubuntu image to a micro SD card with dd to give another try at running Ubuntu on my board, but no luck, I still got that black screen, albeit the system boots properly, as I got the command line using the serial console. During my Android review of ODROID-XU3 Lite, I noticed the system would always revert back to 720p60 video output, and HDMI output settings can be selected in /media/boot/boot.ini with the following content:

ODROIDXU-UBOOT-CONFIG

# U-Boot Parameters

WeTek Play Android & Linux DVB-S2 / DVB-C/T/T2 Receivers are Now Available for 109 Euros

I reviewed Wetek Play Android media player with a DVB-S2 tuner this summer, and although I found it pretty good for a dual core media player, and liked its PVR functions, more work was needed to fix several bugs, and improve “WeTek Theater Live TV” app. Several months later, they must consider their devices ready, as they’ve now launched their online store selling the DVB-S2 and DVB-C/T/T2 versions for 109 Euros, and a version without DVB tuner for 99 Euros, all including free shipping worldwide. Let’s remind us of the specifications: SoC – Amlogic AML8726-MX dual core Cortex A9 @ 1.5GHz with a dual core Mali-400MP GPU System Memory – 1GB DDR3 Storage – 4 GB NAND flash + 1x micro SD slot Video Output – HDMI, AV (CVBS + R/L audio) Audio Output – HDMI, AV, and optical S/PDIF Tuners – DVB-S2, or DVB-C/DVB-T/DVB-T2 depending on model with two […]

PopMetal Rockchip RK3288 Development Board Features Multiple Display Interfaces (HDMI, VGA ,eDP, LVDS, MIPI), GPS and NFC Connectivity

Up to now, we’ve had mainly two development boards based on Rockchip RK3288 Cortex A17 processor: Firefly-RK3288 is a low cost development board powered by Rockchip RK3288 processor selling for as low as $140 shipped, and Radxa Rock 2, a more professional and expansive solution with dual Ethernet, 3G modem and so on. A third RK3288 board has now surfaced which offers a middle ground between Firefly and Radxa boards. PopMetal development board comes with 2GB RAM, 8GB eMMC, 5 video outputs / display interfaces namely HDMI, VGA, embedded DisplayPort (eDP), LVDS, and MIPI DSI, as well as the usual Gigabit Ethernet, Wi-Fi, and Bluetooth connectivity, complemented with GPS and NFC. PopMetal technical specifications: SoC – Rockchip RK3288 quad core ARM Cortex-A17 processor @ 1.8Ghz with ARM Mali-T764 GPU with support for OpenGL ES1.1/2.0/3.0, OpenVG 1.1, OpenCL 1.1, DirectX 11 System memory – 2GB DDR3 Storage – 8 GB eMMC, […]

Boot Ubuntu (Linux) or Android from an SD Card on Rockchip RK3288 Devices

There’s already a method to boot Android from an SD Card on RK3188 devices, which should work with all Rockchip RK3188 devices. Ian Morrison (Linuxium) has now provided a instructions to boot Linux or Android from a (micro) SD Card in Rockchip RK3288 based devices, leveraging work from linux-rockchip community, and especially naobsd. The Android flashing method is slightly different between RK3188 and RK3288, because most Rockchip RK3288 devices make use of eMMC flash, while older Rockchip RK3188 products feature NAND flash, and it appears Rockchip RK3xxx boot priorities (in the BootROM stored in the SoC itself) are as follows: eMMC, SD card, and NAND flash. All that means is that an updated version of the bootloader is needed which looks for a bootable SD card, and although very unlikely, your device could end up being bricked during this procedure. This is not a problem for Open Hour Chameleon since […]

Android 4.4 and Ubuntu 14.10 Tested on Ugoos UM3 mini PC (Rockchip RK3288)

A few days ago I posted pictures of Ugoos UM3, a cute mini PC powered by Rockchip RK3288 quad core Cortex A17 processor, with 2GB RAM, 8GB internal storage, a few USB ports, and Wi-Fi 802.11 b/g/n/ac connectivity. There are so many Rockchip RK3288 based TV boxes and sticks on the market, that it has become difficult to differentiate, so Ugoos has decided to support not only Android 4.4 like all their competitors, but also Ubuntu 14.10, and they’ve provided an alpha release of dual boot Android / Ubuntu images for Ugoos UT3 and UM3 models. Yesterday, I flashed the latest Android/Ubuntu firmware for UM3, and tested the image, so today I can report my findings. First of all, I’d like to point out that I received an earlier sample with various flaws that I reported to Ugoos, and they’ve already committed to fixes: 5V/2A power adapter is not powerful […]

Hardkernel ODROID-C1 is a $35 Development Board Powered by Amlogic S805 Quad Core Processor

Amlogic S805 is a quad core Cortex A5 processor which has found it way into low cost devices such as MK808B Plus TV Stick which can be purchased for as low as $30, or full-sized TV box such as MXQ S85 or MINIX NEO X6. All this low cost devices are nice, but the full source code is not available in your want to adapt them to your need. Luckily, Amlogic releases both an Android SDK, and a buildroot for Linux with GPU and Video Processing Unit (VPU) support, so Hardkernel decided to go ahead, designed a board, and has just launched ODROID-C1 quad core development board for just $35, or the exact price of a Raspberry Pi Model B+, but with much greater specs. ODROID-C1 specifications: SoC- Amlogic S805 quad core Cortex-A5 processor with a Mali-450MP2 GPU (2x fragment cores + 2x vertex shader cores) System Memory – 1GB […]

How To Upgrade Firmware on Ugoos UM3 mini PC

Ugoos released two new dual boot Android / Ubuntu images for Ugoos UT3 and UM3, which reduces the size of the system by 300MB, includes LibreOffice, replaces Firefox by Chromium + PepperFlash plugin, and fixes various bugs: ut3_dualboot_v0.2.rar – For UT3 full sized TV box UM3_dualboot_v0.2.rar – For UM3 mini TV box The firmware update procedure for Rockchip RK3288 is well-known, and Ugoos even includes a word file with flashing instructions in Microsoft Windows with the firmware images. However, it still took me about one hour to find out how to do with Ugoos UM3, so I thought I’d write a post in case others encounter the same issue. I flash the firmware in Ubuntu, so instead of using Android Tool, I flashed it with upgrade_tool command line utility I got from Orion R28 SDK, but you can also download Linux_Upgrade_Tool_v1.2.tar.gz directly. First let’s enter recovery mode. The procedure is […]
