Segger emPower is an embOS RTOS Evaluation Board with a J-Link OB Debug Interface

Segger, a company specializing in embedded software and hardware debugging tools, has recently launched Segger emPower, an evaluation board powered by Freescale Kinetis K66 Cortex M-4 MCU and including a J-LInk OB debug probe (JTAG/SWD), specially designed to evaluate the company’s embOS real-time operating system.

emPower board hardware specifications:

• MCU – Freescale Kinetis K66 (MK66FN2M0VMD18) ARM Cortex M4F MCU @ 180MHz with with 256KB SRAM and 2MB flash memory
• Storage – 1Gbit NAND Flash + micro SD card connector
• Display I/F – 20-pin display adapter connector (5 V/3.3 V, SPI, PWM for backlight control) for small TFT displays
• Connectivity – Fast Ethernet
• USB – 1x USB device, 1x USB host (Full speed)
• Debugging
  • On-board debug probe J-Link-OB with drag & drop (STM32F072, mini A/B-type connector); SWD/SWO only, no CDC/VCOM port support
  • External debug interface (19-pin Cortex-M) including trace
• Expansion
  • 3x Sensor Expansion Interface Devices (SExI) headers providing I2C, SPI buses, UART, GPIO/timer, analog input, power (3.3V I/Os)
  • 2×5-pin headers for spare MCU signals
• Misc – Joystick 4(+1)-way, 1x “FIRE” button, 1x RESET button, rotary input (potentiometer to ADC), 4x bicolor LEDs
• Power Supply – 5V via USB host port
• Dimensions – 99 mm x 80 mm

The board is pre-loaded with SEGGER’s embOS real-time operating system, and evaluation versions of emFile file systems, emWin graphics library , as well as emUSB Host & Device stack, and TCP/IP stack embOS/IP are also included.

Some of embOS features include:

• Zero interrupt latency time.
• High resolution time measurement (more accurate than tick).
• Power management: Unused CPU time can automatically be spent in halt mode, minimizing power consumption.
• Full interrupt support: Most API functions can be used from within the Interrupt Service Routines (ISRs).
• Automatic resolution of priority inversion.
• Unlimited priorities: Every task can have an individual priority => the response of tasks can be precisely defined according to the requirements of the application.
• Unlimited number of tasks, event flags,semaphores, message queues, mailboxes and software timers.
• Time resolution tick can be freely selected (default is 1ms).
• Nested interrupts are permitted.
• High precision per task profiling. Real time kernel viewer (embOSView) included.
• Debug build performs runtime checks, simplifying development.
• Support for ARM, ColdFire, AVR, Reneasas H8/M16/M32, PIC32, etc…

emPower board can be purchased for 98 Euros + shipping. More information is available on Segger emPower and embOS RTOS product pages.
