HMP, Real-Time Linux and Xenomai – A Look at Three Options to Develop Real-Time Linux Systems on Application Processors

NXP-i.MX7-BLock-Diagram

This is a guest post about Heterogeneous Multicore Processing (HMP), Real-Time Linux, and Xenomai to develop real-time Linux systems written by Guilherme Fernandes, Raul Muñoz, Leonardo Veiga, Brandon Shibley, all working for Toradex. Introduction Application processor usage continues to broaden. System-on-Chips, usually powered by ARM Cortex-A cores, are taking over several spaces where small ARM Cortex-M, and other microcontroller devices, have traditionally dominated. This trend is driven by several facts, such as: The strong requirements for connectivity, often related to IoT and not only from a hardware point of view but also related to software, protocols, and security The need for highly interactive interfaces such as multi-touch, high-resolution screens, and elaborate graphical user interfaces; The decreasing price of SoCs, a consequence of its volume gain and new production capabilities. Typical cases exemplifying the statement above are the customers we see every day starting a product redesign upgrading from a microcontroller […]

Raspberry Pi Compute Module 3 to be launched by the end of the year, used in NEC displays

Eben Upton had already mentioned the Raspberry Pi Foundation was working on a Raspberry Pi Compute Module 3 based on the same Broadcom BCM2837 quad core Cortex A53 processor and 1GB LPDDR2 RAM used in Raspberry Pi 3 board earlier this year, but few details had been provided at the time. The module is still not available, but NEC Display Solutions Europe has already announced they are working on integrating Compute Module 3 into commercial displays starting with 40″, 48″ and 55″ models in January 2017, and up to 98″ by the end of next year, used for digital signage and presentation platforms. The Raspberry Pi Foundation goes on to say they’ve been working on NEC project for over a year now, and they expect to release Compute Module 3 to the general public by the end of the year. Price and complete technical details have not been released yet. […]

Gumstix Nodana 96BCE 96Boards Compatible Baseboard Takes Intel Joule Module

96Boards is an initiative from Linaro, an engineering organization focusing on ARM development, to define some hardware and software specifications for development boards. But since 96Boards specifications are open, Gumstix decided to create the first x86 board compliant with 96Boards CE hardware specifications with Nodana 96BCE baseboard powered by Intel Joule Module. For obvious reasons, this will never be an officially supported 96Boards.org platform. Nodana 96BCE board specifications: SoM – Intel Joule Module based on Intel Atom T5700 or T5500 processor with up to 16GB storage, 4GB RAM. External Storage – 1x micro SD card Video Output – 1x HDMI port USB – 2x USB 3.0 ports, 1x USB 3.0 type C port Expansion Headers 96Boards Low Speed connector with I2C, SPI and UART 96Board High Speed connector with MIPI DSI and USB 2.0 Power Supply – 8 to 18 V (if it follows 96Boards CE specs) Dimensions – 85 […]

Setting a VoIP SIP user agent with Embedded Linux

This is a guest post by Leonardo Graboski Veiga, working for Toradex. Introduction This article’s main goals are: to cross-compile the PJSIP libraries and the PJSUA API reference implementation; deploy it to the target system; give an overview about the SIP protocol; and explore the reference implementation features, regarding audio only. For this purpose, a Computer on Module (CoM) from Toradex was chosen in the following configuration: Colibri iMX6DL* + Colibri Evaluation Board. The evaluation board and CoM are displayed in Figures 1 and 2, respectively.   VOIP or Voice over IP, is a term designed to refer to a set of methods and technologies targeted for the implementation of telephony services over the Internet. For the purpose of this article, the scope will be limited to the use of a reference implementation built upon the SIP communication handling protocol by means of the PJSIP libraries and PJSUA2 API. If […]

ArduCAM has designed a Tiny Coin-Sized Raspberry Pi Compatible Module

Now you can design your own custom hardware and leverage Raspberry Pi software, by integrating Raspberry Pi Compute module (and soon Raspberry Pi 3 Compute module) into your custom designed baseboard. But if you’d like something more compact, and even more compact than a Raspberry Pi Zero or RPi Compute module, ArduCAM has been developing a 24x24mm Raspberry Pi compatible system-on-module powered by Broadcom BCM2835 processor. ArduCAM has also designed a small adapter board “UC-343 Rev. A” for the module with the following specifications: SoC – Broadcom BCM2835 ARM11 Processor @ 700 MHz (or 1GHz?) with Videocore IV GPU System Memory – 256MB/512MB LPDDR2 Storage – micro SD card slot USB – 2x micro USB ports including one for power only Camera – 1x MIPI CSI connector supporting 5MP or 8MP Pi cameras (dual camera support) Expansion – AV output header 16-pin and 8-pin headers (unpopulated) with GPIOs, 2x I2C, […]

sModule SBC-x6818 Development Kit based on Samsung S5P6818 Processor Includes a 7″ Touchscreen

For some reasons, Samsung S5P4418 and S5P6818 quad and eight Cortex A53 core processors – likely made by Nexell – have been quite popular with embedded systems companies based in China. So after Graperain, Boardcon, and FriendlyARM, there’s at least one another company offering solutions with either processor, as sModule, a subsidiary of CoreWind, has now launched systems-on-module, single board computers, and development kits with the 64-bit ARM SoCs. In this post, I’ll cover one of their development kit including their CORE6818 CPU module, a baseboard, and an optional 7″ capacitive touch display.. sModule SBC-x6818 development kit specifications: CORE6818 CPU module SoC – Samsung S5P6818 octa-core ARM Cortex A53 processor @ 1.4 to 1.6 GHz with Mali-400MP 3D GPU System Memory – 1GB DDR3 (2GB optional) Storage – 8GB eMMC Flash (4 & 16GB optional) Ethernet – Realtek RTL8211E Gigabit Ethernet transceiver 180-pin “interface” to baseboard Power Supply – 3.7 […]

Boardcon MINI6818 CPU Module Features Samsung S5P6818 Octa-core Processor

Update: a defect has been found, so the board is not for sale anymore. Samsung S5P6818 octa-core Cortex A53 processor has already been found in several single board computers and development boards including Graperain G6818 SBC and NanoPi M3 board, but so far I had not seen it implemented into a system-on-module to be used in custom designs, and that’s just was Boardcon did with their MINI6818 CPU module. Boardcon MINI6818 SoM specifications: SoC – Samsung S5P6818 octa-core ARM Cortex A53 processor @ 1.4GHz with Mali-400MP 3D GPU System Memory – 1GB DDR3 Storage – 4GB eMMC Flash 2x 100-pin board-to-board connectors with 1.27 pitch: 5x UART, I2C, SPI 1x USB2.0 Host, 1x USB HSIC Host, 1x USB2.0 OTG, LCD (TFT/LVDS/MIPI) Gigabit Ethernet I2S, CIF (not sure what it is), Audio HDMI GPIOs ADC PWM HSMMC/SD Power – 5V; AXP228 PMIC Dimensions – 70 x 58 mm (8-layer PCB) The […]
