Linux 4.11 Release – Main Changes, ARM & MIPS Architecture

Linus Torvalds has just released Linux 4.11: So after that extra week with an rc8, things were pretty calm, and I’m much happier releasing a final 4.11 now. We still had various smaller fixes the last week, but nothing that made me go “hmm..”. Shortlog appended for people who want to peruse the details, but it’s a mix all over, with about half being drivers (networking dominates, but some sound fixlets too), with the rest being some arch updates, generic networking, and filesystem (nfs[d]) fixes. But it’s all really small, which is what I like to see the last week of the release cycle. And with this, the merge window is obviously open. I already have two pull request for 4.12 in my inbox, I expect that overnight I’ll get a lot more. Linux 4.10 added Virtual GPU support, perf c2c’ tool, improved writeback management, a faster initial WiFi connection (802.11ai), and more. Some notable changes for Linux 4.11 include: …

$6 LicheePi Zero ARM Board Runs Linux 4.10, Supports Lots of Add-On Boards (Crowdfunding)

We’ve already covered LicheePi One board powered by Allwinner A13 processor, but it was not for sale out of China, and the developers are now back with LicheePi Zero board/module, slightly bigger than an SD card, featuring Allwinner V3s processor, and offered for as low as $6, or $8 with WiFi via an Indiegogo campaign. LicheePi Zero specifications: SoC – Allwinner V3s ARM Cortex A7 processor @ up to 1.2 GHz with an ARM Mali-400 GPU, 512Mbit (64MB) DDR2 on-chip Storage – micro SD card slot, SPI flash (not 100% clear if it will be populated when shipped to backers) Display – FPC40 RGB Connector with support for 800×480 RGB LCD Audio – Audio codec USB – micro USB OTG port Expansion 2x 15 headers with 2.54mm pitch, breadboard friendly with GPIOs, 2x UART, 1x SPI, 2x I2C,ADC, 1x PWM 2x  30 half-holes with 1.27mm pitch with OTG USB,MIPI CSI,EPHY,RGB LCD, more GPIOs RGB connector can take add-on boards for …

Allwinner V3s Dual Camera SoC Comes with 64MB DRAM

Most SoCs have a very limited amount of internal SDRAM just enough to load the bootROM code, but a few integrated a few MB of RAM on-chip such as Renesas RZ/A1H with 10MB on-chip DRAM, in order to reduce costs for some applications that may not require external RAM. Allwinner V3s, designed for dual camera solutions, appeared to be such an SoC with 64MB (512Mbit) on-chip DDR2 RAM, but the block diagram seems to imply it is a System-in-Package (SiP) instead. Nevertheless you still get a single chip with an ARM Cortex A7 processor, two ISPs, a video engine, 64MB RAM, and more. Allwinner V3s main features & specifications: CPU – ARM Cortex-A7 @ up to 1.2 GHz Memory – Integrated 64MB DDR2 DRAM Storage I/F – SD 2.0, eMMC 4.41, SPI NAND flash, SPI NOR flash Audio Codec – 92dB audio codec supporting 2x ADC channels and 2x DAC channels, 1x low-noise analog microphone bias output, 1x microphone input …

$64 Allwinner V3 Action Cameras Support 4K Video Recording (or Not?)

Cheap_4K_camera

An “Allwinner V3 4K Ultra HD DV Sport Camera” just appeared in GeekBuying product feed which the company sells for $84.39, and searching for alternative sellers led me to Soocoo F60 4K action camera sold for $63.34 on GearBest. Both cameras look the same, and the price appears amazing cheap as 4K cameras such as GoPro Hero4 or Sony X1000V normally sell for $500 and more. But one of the tricks is that both “4K” cameras are likely based on Sunchip 4K camera design, which does support 4K video recording, but only at 15 fps. Soocoo F60 camera specifications: SoC – Allwinner V3  ARM Cortex A7 processor @ 1.2GHz System Memory – N/A Storage – micro SD card up to 64GB Display – 2″ LCD Camera OmniVision OV4689 image sensor (4MP according to sensor page, but 16MP on camera description, probably achieved with extrapolation). 170-degree wide angle Recording time up to about 90 minutes at 1080P 30fps Video recording – …

Allwinner CedarX Media Codec Library GPL/LGPL Compliance Update

Last month, I wrote about potential open source licenses and VP6 copyright infringement by Allwinner with their CedarX media codec library, and then since there’s been a few developments. First, Allwinner sent me an email saying they’ve now updated Cedarx library and referring my previous article. Here’s an extract: Here, I have some update of the Allwinner’s open-source status. We have done a lot of discussion with the developers from the linux-sunxi communication about the software license of CedarX. For each question or requirement asked by the developers, Allwinner has identify and try to give the best solution. Now, we believe Allwinner’s CedarX license is fully compliant and resolves concerns from the community. And you can take the announcement https://www.mail-archive.com/[email protected]/msg10597.html as a reference. Allwinner is always supporting the open-source, and try to do better and better. You can see some update on the github https://github.com/allwinner-zh, and some feedback from developers: https://github.com/allwinner-zh/bootloader/issues/5. It’s difficult to make everyone happy, but we believe …
