Unlocking and Erasing FLASH with Segger J-Link Posted on October 5, 2014 by Erich Styger When using a bootloader (see “ Serial Bootloader for the Freedom Board with Processor Expert “), then I usually protect the bootloader FLASH areas, so it does not get accidentally erased by the application;-).

SEGGER Microcontroller is a private multinational company dealing in middleware for embedded devices as well as development and programming tools. The company was founded in 1992 and is headquartered in Monheim am Rhein, Germany with US offices in Gardner, Massachusetts and Milpitas, California.

1embOS

embOS[edit]

J-Link PRO is an enhanced version of the SEGGER J-Link. This emulator supports ARM/Cortex and Renesas RX devices. The J-Link RX Adapter (Sold Separately). I have Segger J-Link EDU probe, which is a very basic one, and try to use J-Flash-Tool with it. Unfortunately the tool in it's free version is not able to program flash chips. This can only.

embedded Operating System (embOS), is a Real-time operating system, developed by the Company SEGGER Microcontroller. embOS is designed to be used as a foundation for the development of embedded real-time applications for a wide range of microcontrollers.

Features[edit]

embOS is an RTOS for all embedded applications.embOS is written from scratch by the SEGGER Microcontroller company using Ansi C and assembler. Other features are:

unlimited amount of tasks (only limited by the amount of available memory)
preemptive scheduling with up to 2³² priorities
Round Robin with adjustable time-slices for tasks with equal priority
adjustable time resolution (default is 1ms)
software timers
low power and multi-core support
safe communication among tasks using:
- task events with up to 32 events per task
- event objects
- resource and counting semaphores
- mailboxes
- queues
full interrupt support
API can be called from assembly, C and C++ code

In addition to embOS, embOS-MPU offers memory protection by using the hardware's memory protection unit as well as additional software mechanisms to prevent one task from affecting the entirety of the system.

embOSView[edit]

embOSView is a tool for analysis of the running target application on an embedded system using embOS. For communication, embOSView can use UART, memory read/write for Cortex-M and RX CPUs, DCC for ARM7/9 and Cortex-A CPUs as well as ethernet.Beside system variables and software tracing, embOSView also lists all tasks with following information:

ID: Task ID, which is the address of the task control block
Name: Name assigned during creation
Status: Current state of task (ready, executing, delayed, reason for suspension)
Data: Depends on status
Timeout: Time of next activation
Stack: Used stack size/max. stack size/stack location
CPU Load: Percentage CPU load caused by task
Run Count: Number of activations since reset
Time Slice: Round robin time slice

Field of Application[edit]

embOS is used in a variety of embedded systems in the fields of application like:

Industrial Controls
Internet of Things
Networking
Consumer electronics
Safety critical devices
Automotive
Medical devices
Avionic

It is supported by popular SSL/TLS libraries such as wolfSSL, thus maintaining embedded security standards across industries.

Supported Devices[edit]

embOS supports all cores and compilers, e.g.:

ARM7/9/11, ARM Cortex-A/R/M, Altera NIOS2, AVR, AVR32, C16x, CR16C, ColdFire, H8, HCS12, M16C, M32C, MSP430, NIOS2, PIC18/24/32, PowerPC, R32C, R8C, RL78, RH850, RX100/200/600/700, RZ, SH2A, STM8, ST7, S08, V850, 78K0, 8051, Xtensa, ...

GCC, IAR, Keil MDK, Tasking, GreenHills, CodeWarrior, Renesas compiler CCRX, CCRL, ...

J-Link[edit]

Segger is most noted for its JTAG / SWD emulator for ARM-based microcontrollers that have ARM7 / ARM9 / ARM11, Cortex M0 / M0+ / M1 / M3 / M4 / M7 / M23 / M33, Cortex R4 / R5 / R8, Cortex A5 / A7 / A8 / A9 / A12 / A15 / A17 cores, Renesas RX, and Microchip PIC32. This device is called the J-Link.^[1] It is also repackaged and sold as an OEM item^[2] by Analog Devices as the mIDASLink, Atmel as the SAM-ICE, Digi International as the Digi JTAG Link, and IAR Systems as the J-Link and the J-Link KS. This is the only JTAG emulator that can add Segger's patented Flash breakpoint software to a debugger to enable the setting of multiple breakpoints in Flash while running on an ARM device which is typically hindered by the limited availability of hardware breakpoints.^[3] For enhanced emulation features Segger offers a Trace Emulator, J-Trace that works with the ARM ETM interface and enables engineers to trace back their code execution.
