Raspberry Pi 3 To Get ARM TrustZone Support with Linaro OP-TEE Port

If you ever wanted to experiment with ARM Trustzone, and IoT security, you’ll soon be able to do so with the Raspberry Pi 3 board thanks to a port of Linaro OP-TEE (Open Portable Trusted Environment Execution) by Sequitur Labs. Broadcom BCM2737 SoC found in Raspberry Pi 3 board already had TrustZone hardware for isolation and protection for sensitive material such as cryptographic keys, algorithms and data, but the upcoming software release will mean the feature can now be used, and it’s free for trial/evaluation, and  education. Trustzone is also used for DRM (digital rights management), but in the case of Raspberry Pi 3 it will most likely used to teach how to secure the Internet of Things (IoT). The release is scheduled for July 11, with source code and documentation to be available in OP-TEE github account. All you’ll need to get started is a Raspberry Pi 3 board, […]

Android TV 6.0 Ported to Raspberry Pi 3 with 2D/3D GPU Acceleration, but no Hardware Video Decoding (Yet)

Google might be working on Android or Brillo for Raspberry Pi 3, with a new repository created in AOSP, meaning that, if that’s Android,  you won’t probably get the Google Mobiles Services by default, but those can be side-loaded to get access the the Play Store, Youtube, etc… In the meantime, a group of developer have been working Android 6.0 TV port for Raspberry Pi 3. That’s the same team who worked on previous images for Raspberry Pi and Raspberry Pi 2 boards using “peyo” port, and that did not have any support for 2D/3D graphics acceleration, nor hardware video decoding. But they’ve made some improvements for their Android TV 6.0.1 release for Raspberry Pi 3, as 2D/3D GPU acceleration is enabled using the Mesa drivers, and Kodi user interface, game emulators, WelGL in Chrome browser all work relatively well using 1280×720 frame buffer resolution as you can see from […]

Raspberry Pi 3 Repository Has Been Added to Android Open Source Project

Android has been ported to the Raspberry Pi boards in the past, but the images were not really usable because the implementation lacked 2D & 3D graphics support. The good news is that Raspberry Pi 3 is likely to officially support the latest version of Android soon, because rpi3 repository has been created in AOSP about 5 weeks ago. That’s all we know for now. Raspberry Pi 3 could then be part of the second wave of boards officially supported in Android “mainline”, as currently 96Boards Hikey is the only supported board in AOSP. However, If we go down in the git repo to android/device, we can also see MIPS Creator CI40, Aaeon Upboard, i.mx6ul picoimx board, Intel Edison and Minnowboard, and a few others. Some of the boards will run Brillo instead of Android however, or it could be a different project, so we’ll have to see what happens […]

Preliminary Open Source Bootloader for Raspberry Pi Boards Released

Raspberry Pi boards require a closed-source binary to boot. I understand it this is handled by VideoCore IV GPU,  and so  far the Raspberry Pi foundation are not release source code for the bootloader, possibly due to legal reason (e.g. NDA to Broadcom). But I noticed people chatting about an open source bootloader for Raspberry Pi on sunxi-linux IRC channel. The bootloaded called rpi-open-firmware has been developed by Kristina Brooks (christinaa), who previously did some work on the VideoCore IV GPU, as you can see on her blog and github account. Kristina describe the project as follows: This is a small firmware for RPi VPU (VideoCore4) versions 1/2/3 that is capable of initializing VPU PLL (PLLC), UART, SDRAM and ARM itself. It’s intended to be used instead of stock bootcode.bin on RPi’s SD card. You need to have UART to see anything meaningful as far as output goes. This has […]

Linux 4.6 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.6 earlier today: It’s just as well I didn’t cut the rc cycle short, since the last week ended up getting a few more fixes than expected, but nothing in there feels all that odd or out of line. So 4.6 is out there at the normal schedule, and that obviously also means that I’ll start doing merge window pull requests for 4.7 starting tomorrow. Since rc7, there’s been small noise all over, with driver fixes being the bulk of it, but there is minor noise all over (perf tooling, networking, filesystems,  documentation, some small arch fixes..) The appended shortlog will give you a feel for what’s been going on during the last week. The 4.6 kernel on the whole was a fairly big release – more commits than we’ve had in a while. But it all felt fairly calm despite that. Linux 4.5 added […]

LibreELEC (OpenELEC Fork) v7.0.0 Released with Kodi 16.1

It’s not always easy to get along in life, and recently this has been true in Kodi developer community and related project, with Koying leaving his role as the main Kodi Android developer, possibly meaning Kodi 17 won’t get an Android port, and more recently several OpenELEC developers, not satisfied with some of the current project developments, decided to fork it, and create LibreELEC. The team of 25 or so members has now released LibreELEC v7.0.0 based on Kodi 16.1 which had also  been released a few days ago. The changelog only reads: The 7.0.0 release contains Kodi Jarvis 16.1 (final) and a fix for Verisign SSL certificate changes that impacted Pandora add-on users. It also addresses a bluez crash, a firmware update for Intel Skylake users, and a fix for an Amlogic CEC issue on WeTek Play/Core. Most importantly it also contains our new logo branding. The images are […]

Chromium OS for SBC Aims to Turn Popular Development Boards into Chromeboxes

A team of developer has come together last December in order to provide Chromium OS, the open source project which Chrome OS is based on, to single board computers such as Raspberry Pi boards. So far, they’ve provided Chromium OS images for Raspberry Pi 2 & 3, but more boards should be supported in the future. The latest version 0.5 release is said to be usable, but WiFi, Netflix, and HTML5 video are not working. The installation procedure is standard. You simply need to download and uncompress the archive (e.g. SamKinison_v0.5_Pi3_16GB.tar.xz), and dump it on a micro SD card with Win32DiskImage or dd. They have released different images for Raspberry Pi 2 & 3, and different SD card sizes (2GB and 16GB). Chromium OS is using 12 partitions, so that may be why they don’t provide a single image and resize the file system during the first time. You can […]

What’s the Best Android TV Box?

[Update December 26, 2017: I’ve posted a new version of this post entitled “What’s the Best Android TV Box (2017/2018 Edition)?“. I’ll leave the post below to have an historical perspective] I often get asked which TV box to buy, or what the best Android TV box is, and the answer is the TV box that fits your needs for the lowest price point possible. Considering there are around 2 millions apps for Android, they are multitudes of use cases, and you can’t provide a single answer for everybody. So I’ll provide a list of things to look for beside the processor, and three TV boxes that I think are worth considering, before providing alternatives for people who want cheaper devices. Things to Look for There are still a few things you may want to specifically look for before purchasing an Android TV box: History of regular firmware updates – […]
