MCUBoot is an Open Source Secure Bootloader for IoT / MCUs

May 15th, 2017 5 comments

Bootloaders takes care of the initial boot sequence on the hardware before the operating system takes over. For example, U-boot is often used in embedded systems as the bootloader before starting the main operating systems such as Linux or FreeBSD. MCUBoot is also a bootloader, but it targets the IoT, here referring to MCU based systems with limited memory and storage capacity, and is born out of work on Apache Mynewt OS, when developers decided to develop the bootloader separately from the operating system.

MCUBoot is designed to run on small & low cost systems running on MCU with ~512 KB flash, ~256 KB RAM, and currently supports Zephyr OS and Mynewt, with support for other RTOS also considered. Due to constraint the bootloader uses minimal features with a flash driver, a single thread, and crypto services. The project also aims at solving security and field firmware updates. To address the latter, the flash is partitioned in four sections, one for the bootloader, one “slot” with the primary image, a second slot for the firmware upgrade, and a Scratch partition to swap slots when an upgrade is needed. An image trailer at the end of each slot indicates the state of the slot.

You’ll find the source code in MCUBoot repository in Github, and you may want to watch the presentation at Linaro Connect Budapest 2017 for more details.

Cambrionix PowerPad 15S is a 15-Port USB Hub with 2.1A Output, Control API, Serial Console, Power Consumption Monitoring

April 8th, 2017 8 comments

Many development boards are powered over USB, usually via a micro USB ports, and if you have one board, you’d just use a 5V USB adapter with the right amperage, and it will work fine as long as you have a low resistance USB cable (AWG20 cables recommended for higher loads).  But when you start to running multiple boards using power strips with USB adapter start to take space, so USB hubs are much more convenient. However, you need to find one that delivers enough power, is reliable, and possible allows per port power control. The guys at LAVA (Linaro Automated Validation Architecture) are using a lot of boards to validate software developed by Linaro and their members, with the boards having to run 24/7, and they had various misfortunes with USB hubs, but as Dave Pigott reports they’ve now found that USB hub of their dream with a 15-port USB hub from Cambrionix which should be their PowerPad 15S model.

Cambrionix PowerPad15S technical specifications:

  • 15x USB port supporting charge and sync with up to 2.1A per port
  • 1x USB host port
  • Control Interface – Cambrionix API, Terminal Command Session, SSH, Minicom
  • Charging Method – Cambrionix VIC “Very Intelligent Charging Protocol”
  • Power Supply – 180W external power supply
  • Certifications – CE, FCC, Underwriters Laboratory (UL), WEEE and RoHS

Each port of the USB Hub can be controlled individually (charging, syncing, or off modes), allows retrieval of VID/PID data, and records power consumption (amps, charging time, total power consumed).  The hub can be monitored and controlled using LiveViewer App for Window or Mac OS, but if you want to automate the USB port, for example to power cycle a board that does not answer to ping request, you may want to use the Cambrionix API available for Linux x86/ARM, Windows, and Mac OS.

When Dave connect the HUB to his (Linux) laptop he noticed it was detected as  a serial device only, and after configuring ser2net, he could login via telnet, and help listed a bunch of commands to control each port. As he connected a Hikey boar, he found a command to check all the ports status with their current draw, so he wrote a Python script to control the port as he wanted.

They also found EtherSync Hub from the same company with that’s running Linux, and can be controlled from the network over Ethernet. LAVA team has been running both types of hubs for a while and found them to be reliable, and will update the complete lab with them.

Cambrionix has other USB charging product with various number of ports, and form factor, including a USB charging 1U rack, or a 54-port data transfer USB hub. Check out their products page for details. Those are all nifty USB hubs, but as expected price is pretty high with PowerPad 15 sells for $660 on Amazon US (that’s $44 per USB port), and while there are some other cheaper Cambrionix models on Amazon UK, they probably lack advanced functions like power monitoring. [Update: I’ve been informed model PowerPad 15C (notice the extra C) is much cheaper, as it sells for £159 ex vat (~$200) on Multipad UK. The main difference is that it does not support sync mode compared to PowerPad 15S model].

  • Dimensions – 85 x 54 mm

The board only supports Android 6.0, with Linux support depending on what Mediatek decides to do. You’ll find some hardware and software document on the Wiki which still has many non-working links…, and none of them seem related to the Pro version yet.

If you want to use 3G or 4G cellular , you’ll need to get  “Mediatek X20 RF sub-board” that connects to X20 board via two board-to-board connectors with the following key features:

  • Modem Features – World-mode Modem with Single RF for all Markets
    • FDD/TDD LTE R11 Cat-6 (300Mbps/50Mbps) with 2x20MHz DL carrier aggregation support

  • RF Board Band Support – WCDMA band 1,8; TDD-LTE band 38,39,40; FDD-LTE band 1,3
  • Dimensions – 100 x 71 mm

Charbax interviewed the company at Linaro Connect Budapest 2017 where they showcased their new X20 Pro board and corresponding add-on boards, as well as the upcoming Mstar Altra board compliant with 96Boards TV Platforms specs (7:48 mark in video) based on Mstar MSD6A838 quad-core ARM Cortex-A53 SoC with 4K M-Genuine Video Engine supporting Motion Estimation/Motion Compensation (MEMC), HDR, color enhance, de-noise, and so on.


It’s unclear whether Mediatek X20 Pro is available now, and we don’t know the price yet, but considering the non-pro version sells for $200, we could probably expect the 4G version to sell between $250 to $300 with the RF baseboard and SIM card adapter board. Some more information is available on the product page.

Socionext SC2A11 Low Power Server Processor Comes with 24 Cortex-A53 Cores, Scales up to 1536 Cores via PCIe

March 15th, 2017 7 comments

Socionext SC2A11 is an 24-core (tetracosa) ARM Cortex-A53 processor designed for low-power server system suitable for edge computing, web server & indexing, cloud computing, and any applications that do not require high single thread peak performance. The company also designed SC2A20 switch SoC that allows up to 64 SC2A11 processors (1536 cores) to communicate over PCI Express using Socionext DDT (Direct Data Transaction).

SC2A11 SoC specifications:

  • Processor – 24x ARM Cortex-A53 MPCore cores @ up to 1GHz, with 32KB/32KB I/D L1 cache, 256 KB L2 cache, and 4MB L3 cache
  • Memory I/F – DDR4-2133Mbps 64-bit + ECC
  • Flash I/F – HSSPI, eMMC
  • PCIe – PCI Express Gen2, Root/Endpoint select, 4 lanes (2 systems/ for SoC IF)
  • LAN – 2x 1Gbps with IPSec Network Offload Engine (wire-speed)
  • Serial I/F – UART, I2C, GPIO

The company did not provide any info about software, but it’s safe to assume it’s running Linux. There’s some code on the Linux mailing list for other Socionext processor,  but nothing for SC2A11. Another interesting use case is to connect several processor element card (PEC) based on SC2A11 using SC2A20 switch SoC, and a few Socionext MB86M30 ASSP via PCIe to encoding raw videos to 4K HEVC / H.265 videos @ 60 fps.

Media Transcoder Server

Socionext was at Linaro Connect Budapest 2017 demonstrating some of those PECs, and Charbax checked them out at the demo event, where they showcase the boards, and explained a little about them, and their relation with Linaro (as a member).

You won’t find than many details on Socionext SC2A11 product page, but at least you can inquire the company if you need more information.

The first board is BlueSky IE board with the following key specifications:

  • SoC – RDA Micro RDA5981A ARM Cortex-M4 Wireless MCU with 64KB ROM, and 32KB cache
  • System Memory – 485KB SRAM. It’s unclear if that’s only the on-chip SRAM, and there’s also some external PSRAM added.
  • Storage – 8Mb NOR flash 802.11 b / g / n HT20 / 40 mode
  • Connectivity – 802.11 b/g/n WiFi with support for  HT20 / 40 modes
  • Crypto security hardware

The second board is WRTnode IE:

  • SoC – Mediatek MT7697 ARM Cortex-M4 wireless MCU @ up to 192MHz with 64KB ROM, 353 KB SRAM
  • Storage – 4Mb NOR flash
  • Connectivity – 802.11 b/g/n WiFi and Bluetooth 4.2 LE
  • Crypto security hardware

Neither boards are available now, and Linaro and their members must still be working on them before the launch. There’s currently very little information about RDA5981(A) MCU except on some Chinese websites, but you’ll find many more resources for Mediatek MT7697. Mr Grey also demo’ed Orange Pi i96 board announced last year with an Ubuntu distribution developed by Shenzhen Xunlong Software.

Linaro also announced four new members with Acer joining the Linaro IoT and Embedded (LITE) Group, Guizhou Huaxintong Semiconductor Technology Co., Ltd (HXT Semiconductor) & Fujitsu Limited coming to the Linaro Enterprise Group (LEG), with the latter also joining as founding member of the LEG High Performance Computing Special Interest Group (HPC SIG), and Google joined as a Club member.

You might be interested in watching the keynote with all those announcements, and to be more up-to-date with Linaro’s progress.

Thanks to Theguyuk for the tip.

Linaro Home Group Releases “AOSP” Android TV for Hikey Board

February 3rd, 2017 1 comment

The Linaro Home Group (LHG) was setup to work on “open source software for ARM-based set top boxes, smart TVs, media boxes, TV dongles and home gateway products”, and after having worked on OP-TEE (Open Portable Trusted Environment Execution) firmware as one of their first endeavors, they’ve now ported Android Open Source Project (AOSP) Android TV to 96Boards compliant Hikey board.

Android TV is based on Android, but adds the TV Input Framework and the Lean Back APIs with the user interface designed for larger displays. LHG has not changed the apps and higher level software from AOSP, but they’ve made sure it could work on Hikey board by working on the Linux drivers and Android user space stack to make sure the Live TV App and Android TV Channel Service implemented in AOSP can work properly on the hardware.

If you want to try it on your own Hikey board, you can do so by building AOSP Android TV from sources.

Hikey Board – Click to Enlarge

Now that does not mean any random Chinese TV box manufacturer will be able to ship TV boxes running “Android TV” instead of Android for phone or tablet, as AOSP lacks Google Mobile Services (GMS), and Android TV solutions must be licensed and approved by Google, and must pass various tests such as the Android Compatibility Test Suite (CTS), the Compatibility Definition Document (CDD) and various audio & video performance criteria. But at least most of the low level software should be taken care of, so it would simplify and speed up development.

Android TV Sample App – Click to Enlarge

Hikey board hardware complies with 96Boards “Consumer Edition” specifications, but lacks typical TV box features such as an IR receiver, which is why 96Boards TV Platform specifications were published last year. LHG probably started with Hikey because development has been going on for a longer time, and the platform is more mature, but one of the next steps will be to work on 96Boards TV Platform compliant boards such as HiSilicon Poplar board.
