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 […]

Mediatek MT8173 Quad Core big.LITTLE ARM Cortex A72/A53 Processor Code Submitted to Linux Mainline

[Update: MT8173 processor has now been announced, and it’s using Cortex A72 and A53 instead of A57/A53, as initially shown in the Linux kernel source code] Mediatek is not exactly known to compliant with open source licences, or be involved with the open source community. But the company is certainly going into the right direction with their cooperation with Google leading to source code release for Android One smartphones, and the recently launched Mediatek Labs for community projects, starting with LinkIt One IoT platform. Mediatek is also regularly submitting code to the Linux ARM Kernel mailing list, and yesterday code was submitted for Mediatek MT8173 SoC, a 64-bit ARMv8 processor with two Cortex 53 and two Cortex 57 cores in big.LITTLE configuration. As far as I know, it could be the first Mediatek SoC with “big” Cortex A57 cores. Code snippet from mt8173.dtsi related to CPU cores:

cpus {
+		#address-cells = &lt;1&gt;;
+		#size-cells = &lt;0&gt;;
+
+		cpu0: cpu@0 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a53";
+			reg = &lt;0x000&gt;;
+			enable-method = "psci";
+		};
+
+		cpu1: cpu@1 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a53";
+			reg = &lt;0x001&gt;;
+			enable-method = "psci";
+		};
+
+		cpu2: cpu@2 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a57";
+			reg = &lt;0x100&gt;;
+			enable-method = "psci";
+		};
+
+		cpu3: cpu@3 {
+			device_type = "cpu";
+			compatible = "arm,cortex-a57";
+			reg = &lt;0x101&gt;;
+			enable-method = "psci";
+		};
+	};

cpus {

+ #address-cells = <1>;

+ #size-cells = <0>;

+ cpu0: cpu@0 {

+ device_type = "cpu";

+ compatible = "arm,cortex-a53";

+ reg = <0x000>;

+ enable-method = "psci";

+ };

+ cpu1: cpu@1 {

+ device_type = "cpu";

+ compatible = "arm,cortex-a53";

+ reg = <0x001>;

+ enable-method = "psci";

+ };

+ cpu2: cpu@2 {

+ device_type = "cpu";

+ compatible = "arm,cortex-a57";

+ reg = <0x100>;

+ enable-method = "psci";

+ };

+ cpu3: cpu@3 {

+ device_type = "cpu";

+ compatible = "arm,cortex-a57";

+ reg = <0x101>;

+ enable-method = "psci";

Linux 3.18 Released

Linus Torvalds released Linux Kernel 3.18 last Sunday: It’s been a quiet week, and the patch from rc7 is tiny, so 3.18 is out. I’d love to say that we’ve figured out the problem that plagues 3.17 for a couple of people, but we haven’t. At the same time, there’s absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn’t make sense. Especially since that would just have then held things up entirely over the holiday break. So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that “Ahaa” moment) over the next week. But in solidarity with Dave (and to make my life easier too 😉 let’s try to avoid introducing any _new_ […]

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 […]

MIPS Creator CI20 Development Board is Now Available for $65

When Imagination Technologies first announced their developer program for MIPS Creator CI20 board, they did not disclose the price, but based on the specifications I estimated that a decent price would be $70 o $80. The company has now announced broad availability of the board, which can be pre-ordered for just $65 or 50 GBP depending on the continent you live in, with shipping scheduled for the end of January 2015. This development board is based on Ingenic JZ4780 dual core MIPS processor with 1GB DDR3, 8GB flash, and features an HDMI output up to 1080p, Audio in and out, a Fast Ethernet RJ45 port, a Wireless module with Bluetooth 4.0 and Wi-Fi, an IR receiver, and expansion headers. Several projects have already been ported by developers who got their free board a few months, ago including XBMC/Kodi, several games such as Spiral Episode 1, and beside Android 4.4 and […]

e-con Systems Unveils eSOMiMX6 SoM based on μQ7 Form Factor, and Ankaa Development Kit

QSeven is one of the many standards for system-on-modules, and it defines both Qseven (Q7) 70x70mm modules, and smaller μQSeven (μQ7) 70x40mm modules. While there are quite a few SoMs following the larger form factor, few modules are based on micro Q7, and e-con Systems eSOMiMX6 has just launched one of these tiny modules with eSOMiMX6 system-on-module powered by Freescale i.MX6 processors, as well the corresponding Ankaa development kit comprised of the SoM and a baseboard. eSOMiMX6 module specifications: SoC – Freescale i.MX6 single, dual or quad Cortex A9 processor @ 800MHz to 1.2 GHz with Vivante GPUs System Memory – 256MB/512MB (Solo only), 1GB (default), or 2GB (dual/quad only) LVDDR3 RAM Storage – 4GB (default) to 64GB eMMC flash, 2MB SPI NOR flash, and SD/MMC + SATA II interfaces via MXM connector Display / Video Output: HDMI up to 1920 x 1080 Dual channel 24-bit LVDS 24-bit LCD RGB MIPI […]
