Linux 3.15 Released

Linus Torvalds announced the release of Linux Kernel 3.15 last Sunday: So I ended up doing an rc8 because I was a bit worried about some last-minute dcache fixes, but it turns out that nobody seemed to even notice those. We did have other issues during the week, though, so it was just as well. The futex fixes and cleanups may stand out, but as usual there’s various other random fixes since rc8 in there too: mainly drivers (drm, networking, sound, usb etc), networking, scheduling and perf tooling. But it’s all been fairly small and quiet, which *may* of course be due to the fact that last week was also the first week of the merge window for 3.16. That might have distracted some developers. I’m not entirely convinced I liked the overlap, but it seemed to work ok, and unless people scream really loudly (“Please don’t _ever_ do that again”) and give good […]

How to Upgrade Firmware for Rockchip RK3066, RK3188, RK3328, RK3288, RK3399 Devices with the Command Line in Linux

Previously I wrote an article entitled “How to Flash Rockchip RK3066 / RK3188 Firmware in Linux” explaining how to use a graphical tool called RkFlashKit to upgrade firmware on Rockchip devices using a Linux computer. This tool had some limitations, and it would just have a subset of features of RkAndroidTool (Windows), and it was not possible to flash “update.img” type of firmware which are often provided and flashed with RkBatchTool in Windows. Luckily there’s now a command line tool called upgrade_tool that allows you to flash the “update.img” firmware files directly from Linux. I’ve already shown how to use it with Radxa Rock, but it’s buried with other instructions, so I’ve decided to make a separate post. This has been tested in Ubuntu 14.04 with Radxa Rock (RK3188) and Measy U2C (RK3066). Ready? Let’s start by downloading and extracting upgrade_tool. You may want to add the installation path to […]

PQ Labs iStick A350-SSD is a Quad Core HDMI TV Stick with an mSATA Connector and a Battery

Since there are now so many quad core HDMI TV Sticks and TV Boxes, it would be easy to discount PQ Labs iStick A350-SSD as yet another Android TV devices powered by Rockchip RK3188 SoC, were it not for its mSATA connector and included battery. The company has also managed to add 3 USB ports, and a micro USB port, in a form factor only slightly bigger than a standard HDMI TV dongle. iStick A350-SSD specifications: SoC – Rockchip RK3188 quad-core Cortex A9 @ 1.6GHz with Mali-400MP4 GPU System Memory – 2GB DDR3 Storage – 4 GB NAND Flash, mSATA connector, micro SD slot Video & Audio Output – HDMI, audio jack Connectivity – 10/100M Ethernet, dual band Wi-Fi 802.11 b/g/n and Bluetooth 4.0 (AP6330 module) USB – 3x USB Host, 1x micro USB Misc – Recovery switch, power button, active cooling system Battery – 270 mAh (3.7V) Power Supply […]

Ubuntu 14.04 and Slitaz on Radxa Rock

Various Android and Linux images are available on Radxa Rock download page, but if you’d like to get newer images or other options, two developers have provided binaries and posted instructions to get Ubuntu 14.04 and Slitaz operating systems, the later currently booting with Linux kernel 3.10. Naoki FUKAUMI has published a miniroot how-to install a Ubuntu 14.04 Core (minimal headless installation) on Radxa Rock and Radxa Rock Lite. Installation should be relatively easy as he provide the update.img for both board so your can use the usual method in Windows (RkBatchTool) or upgrade_tool in Linux. If you don’t have serial console, you’ll have need to flash the parameter file requiring RkAndroidTool in Windows, and the same upgrade_tool in Linux. If once the installation and configuration is complete, you want a desktop environment,you can always run “apt-get install lubuntu-desktop” to install LXDE. SliTaz is a lightweight Linux distribution. I previously […]

Linux Kernel Source Code and Chromium OS Overlay for Rockchip RK3288

A few days ago, we’ve seen Chromium OS running on Rockchip RK3288 development platform. I’ve been informed the source code could have already been released via the newly registered rkchrome github account with Linux kernel 3.10.30 and the overlay files to build Chromium OS for RK3288. There’s also a u-boot repository but it is currently empty. This Linux kernel can also boot Rockchip RK3188 based Radxa Rock development board, but more tests are needed to see if it’s really usable. I’ll have a look at the Linux kernel, and try to build it, and leave the Chromium OS part for later or other people. Let’s retrieve the source code:

git clone https://github.com/rkchrome/kernel.git
cd kernel

1 2	git clone https://github.com/rkchrome/kernel.git cd kernel

We’ve got two kernel config files related to Rockchip in arch/arm/config:

ls arch/arm/configs/ | grep rock
rockchip_chromium_defconfig
rockchip_defconfig

ls arch/arm/configs/ | grep rock

rockchip_chromium_defconfig

rockchip_defconfig

But since this is a recent 3.10 kernel with support for Flattened Device Tree support, and multi-platform support, there’s not much to be seen in these files, and […]
