---

The following needs can be met by linking eDEVS with a JTAG probe with the target hardware:

• Use of the eDEVS functions to support multiprogramming if the debugging ports (serial, Ethernet, etc.) required for eDEVS debugging communication are not available due to hardware limitations
• Debugging a program in flash memory
• Breaking the entire system and using functions specific to JTAG

Compatible JTAG units

eDEVS supports the following JTAG probes of our global partners

JTAG unit name	Manufacturer	Functions
DSTREAM		Communication/execution control linkage
PARTNER-Jet2		Communication/execution control linkage
adviceXross adviceLUNA II		Communication/execution control linkage
J-Link		Communication/execution control linkage

Communication/execution features

eDEVS provides the following two functions by linking via the JTAG standard.

Communication function

Using the JTAG port as a debugging port with the JTAG probe as a communication pathway makes it possible to use all eDEVS functions, including eDEVS's multi-programming tool and system analysis tool software component packaging tool, and others.

Execution control function

Here is an overview of eDEVS-supported JTAG functions.

Main JTAG debugging specific functions

Hardware reset Forced break Step execution Hardware break (command execution break/memory access break) Software break (breaks program code on RAM/flash memory) Download to / editing of RAM/flash memory Depending on the hardware and JTAG probe linked with eDEVS, some functions may not be available.
