On-Chip-Debug using - BDM - JTAG & SWD

BDM, JTAG and SWD Interfaces

PEmicros latest USB Universal Cables are the hardware interfaces between a standard PC and the header on any of a wide range of target system. Depending on the chip they provide access to the Background Debug Mode (BDM), JTAG and SWD interfaces of the microcontroller. By employing the BDM/JTAG/SWD Cable the user can take advantage of "On-Chip-Debugging" to program internal or external FLASH memory devices and to  test the application code in the micro.

A range of price performance points are available with the low cost Universal, the high performance Universal FX and the production Cyclone as alternatives.

Flash memory programming tools are available both for the development and production environments.  See below for details of how they work.

Full control of the on-chip resources via BDM/JTAG/SWD

Full speed in-circuit emulation at a reasonable price

Programming for internal or external EEPROM/FLASH memory devices

Execute until hardware breakpoint

Work with PROG programmer software packages as well as a wide range Compiler debug environments such as CodeWarrior, KDS, Keil, IAR, Atollic, GDB

1.8 to 5 volt versions are available see chip specific information

Very fast downloads and stepping

Interface library and demo for custom testers and software

Cyclone Family

These boxes will connect a PC via Serial, USB or Ethernet to provide a super fast interactive Flash programmer under manual or automatic control.  They can even be disconnected from the PC and used as a standalone Flash programmer.  If you are developing applications for any of the NXP/Freescale devices they are the only CPU specific hardware development tool you will ever need to buy.  They will work with all the software packages shown below:

  Cyclone Universal   For use with 68HC08,  HCS08, HC12, HCS12 families. Interfaces to PEmicro, CodeWarrior and Cosmic debug environments.  As well as  For use with Arm cortex, Kinetis, 55xx/56xx/57xx Qorivva, ColdFire, PPC 5xx/8xx and MAC 71xx,72xx (ARM) families. Interface to ARM GDB server

Also these will program the following devices

  Cyclone for ARM® Cortex devices   For programming ARM Cortex M0-4 based devices from  STMicro, NXP, TI Stellaris and NXP/Freescale Kinetis.
  Cyclone For STMicro   For programming STM32,  STM8 and SPC56  families.
  Cyclone For Renesas   For programming M32C,  M16C, M16C/80,  R8C,  H8 and H8S/Tiny families.

The Cyclones are provided with a full set of flash programming algorithms and are particularly popular in production environments where they can be used with a range of automation options designed for full scale production line programming.

BDM Flash Programmer

An interactive flash EEPROM programming software package that allows you to program/reprogram both internal and external flash devices in-circuit, via a PEmicro interface cable. Perfect for development, production line programming, or field firmware upgrades. PEmicros products contains our entire library of setup files for a particular processor, and includes both interactive and command-line versions for use in development and production.

In-Circuit Debugger

PEmicro's In-Circuit Debugger software - ICD for Windows is a powerful tool for debugging . It uses the processor's background code debug mode, via an interface cable, to give the user direct access to all on-chip resources.

C source-level debugging support for IEEE695 & GNU Full-speed in-circuit emulator Breakpoints with counters for breaking on Nth execution Variables window showing bytes, words, strings, and long words Real-time execution as well as multiple tracing modes Startup and Macro files for automating the debug process Context-sensitive help for all commands Timing measurement and execution count functions Hot keys for setting breakpoints and counters Support for symbolic register files

Integrated Development Environment 

WinIDE allows you to run external programs including assemblers, C compilers, debuggers, and flash programmers from within one environment, with a single hot key for each. WinIDE comes optionally installed with a PEmicro assembler. 

Register File

REGxx allows the user, via the BDM, to view and modify the processor's register fields in both symbolic and numeric format, which removes the tedious process of searching through manual pages for register descriptions. When the user selects a register, the actual processor's memory is read and displayed. The register files work with PEmicro's In-Circuit Debugger software.

PACKAGE with Assembler  

A full 32 bit windows software package consisting of Integrated Development Environment, In Circuit Debugger, Assembler, Programmer, Register File is now available for all CPUs  --  just add the cable of your choice. 

PACKAGE Pro  with C 

PEmicro's package Pros provide all the engineer needs to start using the Gnu Cross Compiler.  It has a version of the GNU/GCC compiler toolset precompiled by PEmicro to operate directly under the Windows environment without requiring the installation of a Unix shell. The compiler is integrated into WinIDE and allows for one-touch compilation of a C-level project. The package includes startup code and linker scripts for the most popular devices. The compiler produces both the Elf/Dwarf 2.0 and S19 output formats; The Elf/Dwarf format is loadable by PEmicro’s in-circuit debugger and the S19 is loadable by PEmicro’s in-circuit flash programmer all of which, along with a suitable BDM/JTAG interface, are included.   The Pro versions of the package are now available for ColdFire and Power PC  Qorivva 55xx/56xx/57xx (AKA NEXUS). 

Unit Library

A library of calls that allow the PC to directly drive the BDM cable.  Ideal if you want to create your own production line test programs.  For an example of the C and Pascal API follow this link. Two versions are available  Windows and Linux x86 (not ARM).
