Linux 4.3 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.3 last week-end: So it *felt* like the last week of the rc series was busy, to the point where I got a bit worried about the release. But doing the actual numbers shows that that really was just my subjective feeling, probably due to the kernel summit and travel back home from Korea. It wasn’t actually a particularly busy week, it’s just that the pull requests were more noticeable in the last couple of days. We had a network update and a late fix for a x86 vm86 mode bug introduced by the vm86 cleanups, but other than that it’s just a collection of various small one-liners all over. Ok, the vm86 mode thing was a one-liner too, it was just slightly more nerve-wracking because it looked scarier than it was before people (Andy) figured out what was going on. The changes from rc7 […]

Android 5.1 SDK Release for Rockchip RK3128 Based FirePrime Board

T-Firefly has just announced the release of Android 5.1 SDK for their newly announced Fireprime development board powered by Rockchip RK3128 quad core Cortex A7 processor. You can get the SDK (fireprime_android5.1_git_20150612.tar), a 6.1GB download with full source code for the board via Baidu or Google Drive, and then upgrade it to the latest version with git pull on the company’s bitbucket account as explained in the Wiki. The SDK must be specific to Fireprime board, but it should be feasible to use to create / modify Android 5.1 firmware for other RK3128 products. If you don’t need the source code, but would just like to install the firmware for Android 5.1, and the other image recently released (Ubuntu 15.04 Desktop or Server, or Android 5.1/Ubuntu 15.04 dual boot image) via the links provided in the announcement. Thanks to Nanik for the tip. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in […]

Radxa Rock Lite Board Price Drops to $39

When the new Radxa Rock Lite was announced for $59 in September 2014, it was one of the most inexpensive quad core ARM Linux development board available on the market. But ODROID-C1 board in December 2014, and especially Raspberry Pi 2 board in February 2015 changed all that, as these two quad core boards sell for $35 before shipping and taxes. So the company has now decided to drop the price to $39 for the Radxa Rock Lite board. Let’s remind us of Radxa Rock Lite specifications: SoC – Rockchip RK3188 ARM Cortex-A9 quad core @ 1.6Ghz + Mali-400 MP4 GPU System Memory – 1GB DDR3 @ 800Mhz Storage – micro-SD SDXC up to 128GB Video Output – HDMI 1.4 up to 1080p@60hz, and AV output.
