Atmel Introduces SAMA5D3 Cortex A5 Embedded MPUs and Evaluation Kits

Atmel has recently announced the Atmel SAMA5D3 series, a family of high performance, low-power microprocessor units (MPUs) based on ARM Cortex-A5 core. The SAMA5D3 series is designed for embedded applications in the industrial space, including factory and building automation, smart grid, medical and handheld terminals, as well as consumer applications such as smart watches, outdoor GPS, and DECT phones. SAMA5D3 family has the following characteristics: ARM Cortex-A5 core up to 536MHz (850DMIPS). Floating point unit (FPU) with up to 3 times the performance of Cortex A8 FPU. 166MHz bus speed delivering up to 1328MB/s bandwidth. Power consumption: <200mW in active mode at 536MHz with all peripherals activated 0.5mW in low-power mode with SRAM, registers retention and <0.5ms wake-up time ~1.2µA in backup mode with RTC running Connectivity: Dual Ethernet and dual CAN ports (Only one model has both) Gigabit Ethernet MAC with IEEE1588 and 10/100 MAC Two CAN controllers 3x […]

Barebox Bootloader Status Update – ELCE 2012

Sascha Hauer, kernel developer at Pengutronix, gives an update about the status of Barebox bootloader at the Embedded Linux Conference 2012 in Barcelona, Spain. Abstract: Booting Linux is still a hot topic on embedded systems. It has been 3 years since the last presentation about Barebox at ELC-E, and the barebox community has grown and developed many new and unique features during that time. The talk gives an update on the status of barebox, including MMU support, compressed images, menu system, automouter, tftp, nfs filesystem, USB updating techniques and other goodies. The presentation is for kernel porters who need a robust, flexible,extensible and well structured tool to bring up Linux on embedded hardware. It is equally suitable for new and experienced barebox users. Agenda of the talk: Tour through Barebox – Basic hardware initialization (SDRAM, clocks), Startup, User Interface, Start operating system, Update and Initial hardware bring-up. Devicetree support Multi-platform […]
