OpenTitan and Microsoft Pluton – The security chips of the future

OpenTitan Security Model

Security is becoming more and more important with critical data exposes to the Internet. Traditionally some PCs, laptops, motherboards, or single board computers would be equipped with a TPM (Trusted Platform Module) designed to secure hardware through integrated cryptographic keys.  More recently, we’ve started to read more and more about secure elements providing hardware-based security for lower-end platforms. Those are external chips, but companies have also started to providing hardware-security within the processor with solutions such as Arm Trustzone or Intel SGX (Software Guard Extensions). But more recently, Google and Microsoft have made announcements about hardware-security IP with respectively OpenTitan open source project and Microsoft Pluton security chip both meant to be embedded into processors. OpenTitan OpenTitan is described as being “the first open-source project building a transparent, high-quality reference design and integration guidelines for silicon root of trust (RoT) chips”. It is backed by Google, Seagate, Nuvoton, Western Digital, […]

NanoPi R4S SBC preview with OpenWrt and Ubuntu Core

NanoPi R4S review

Rockchip RK3399 powered NanoPi R4S router SBC launched at the beginning of the month, and FriendlyELEC kindly sent a review sample to CNX Software. I intended to test thermally performance, Ethernet, and USB like I did for NanoPi R2S and NanoPi NEO3,  but Armbian is not available right now, so I could not use some of the tools I normally used right now. So instead, I tested the board/gateway with the image from FriendlyELEC. First FriendlyCore based on Ubuntu Core 20.04, but there some issues which we’ll detail in this preview, so I then switch to FriendlyWrt built upon OpenWrt 19.07 which works better, but I still encountered some problems. That’s just to say it might be better to wait a little longer until Armbian images are released, or until FriendlyELEC fixes some of the shortcomings. NanoPi R4S gateway unboxing Before testing the software, let’s see what I’ve received. NanoPi […]

LwM2M v1.2 M2M & IoT device management protocol adds support for HTTP and MQTT, LwM2M gateways

LwM2M v1.2

Lightweight M2M (LwM2M) is a REST-based protocol from the Open Mobile Alliance (OMA) for M2M & IoT device management that defines the application layer communication protocol between an LwM2M server and an LwM2M client running on an IoT/embedded device. While LwM2M v1.0 was published in early 2017, we first covered the new protocol a year earlier as Imagination Technologies released the source code for the LwM2M stack running on MIPS Creator Ci40 development board.  Since then we’ve mostly seen the LwM2M protocol supported in cellular LTE IoT modules including Quectel BC66 and u-Blox Sara-R410M, as well as the now-defunct Samsung Artik WiFi IoT modules. LwM2M v1.0 was followed by v1.0.1 and v1.0.2 for bug fixes, and v1.1, but OMA has now announced LwM2M v1.2 protocol that adds the following new features: New transports for LwM2M: MQTT and HTTP Optimizations for the bootstrapping and registration interfaces to reduce the amount of […]

Raspberry Pi CM3 “Industrial IoT” baseboard features PoE, 4G LTE modem, and isolated I/Os

Raspberry Pi CM3+ PoE 4G LTE

The Raspberry Pi Computer Module 4 (CM4) may have been introduced in October, but that does not mean people have stopped all development on Raspberry Pi CM3/CM3+ hardware, and Waveshare has just launched a carrier board for the module with PoE support and a 4G LTE modem namely Simcom SIM7600G-H module with 3G and 2G fallback. The board also offers Ethernet and WiFi connectivity, HDMI and MIPI CSI/DSI video interfaces, multiple USB ports, as well as isolated CAN bus, RS485, RS232, and other I/Os for industrial applications. Compute Module PoE 4G board specifications: Storage – MicroSD card slot for Raspberry Pi CM3 Lite / CM3+ Lite modules Video Output – HDMI 2.0 port, MIPI DSI connector compatible with the official Raspberry Pi display Audio – 3.5mm stereo audio jack, 4-pin speaker connector for 8Ω/5W speaker Camera I/F – 2x independent MIPI CSI ports Connectivity 10/100M Ethernet RJ45 port with PoE […]

Jetson Mate Cluster box takes four Jetson Nano/Xavier NX modules

Jetson Mate Cluster Box

While we’ve seen plenty of cluster boards based on Raspberry Pi SBC or Compute Modules, I had never seen clusters of Jetson modules. Those already exist, and PicoCluster has a few, but what made me write this post today is Seeed Studio’s Jetson Mate cluster box equipped with a carrier board taking up to four NVIDIA Jetson Nano or Xavier NX modules, an enclosure covered with a largish cooling fan with RGB LED for good effect… Jetson Mate specifications: SoM compatibility – Jetson Nano or Jetson Xavier NX via four SO-DIMM sockets Video Output – HDMI 2.0 Networking Gigabit Ethernet (RJ45) port Microchip KSZ9896CTXC 6-port GigE Managed Switch for internal networking between the modules and to the outside world Camera – 2x MIPI CSI connectors USB – 4x USB 3.0 ports (one per module), 1x USB 2.0 port, 1x USB-C port for power Debugging – UART debug pins (4x pairs, […]

Ollie USB board exposes isolated UART, CAN, USB, RS485 & RS232 interfaces (crowdfunding)

Ollie USB board

Just like months, we wrote about Tigard open-source USB FT2232H board for hardware hacking with easy access to OpenOCD, JTAG, Cortex, flashrom interfaces used to debug/flash boards, extra I/Os with UART, SPI, and I2C, as well as a header to connect a logic analyzer and observe signals. If the board does not exactly match your requirements, Ollie USB board might, also it may not serve exactly the same purpose(s). The board acts as a USB bridge to isolated UART (x2), CAN, USB, RS485, and RS232 interfaces. Ollie specifications: MCU – STMicro STM32F042 Arm Cortex-M0 microcontroller with CAN interface Host interface – Micro USB port Isolated interfaces (all with ESD protection) 2x UART ports up to 12 Mbps with 1.8/3.3/5 V voltage levels (set by slide switch) CAN bus based on CANable/CANtact open hardware, flashed with dual firmware CANtact and Candlelight (switch selectable) and equipped with termination resistor switch Downstream USB […]
