The bdiAccess library can be used to access BDI3000 functions. With this library, a Windows/Unix

program can take advantage of the BDM/JTAG debug interface of the connected target processor

and execute tasks like:

• Read/Write target registers

• Read/Write target memory

• Reset/Startup target

• Flash programming

• Start/Stop program execution

This Installation Manual shows how to connect the BDI3000 to the target and how to install the bdi-

Access software. The interface to the library is speciﬁed in a different document that is target inde-

pendent.

1.1 BDI3000

The BDI3000 is the main part of the bdiAccess system. This small box implements the interface be-

tween the BDM/JTAG pins of the target processor and a 10/100Base-T Ethernet or RS232 connector.

The ﬁrmware of the BDI3000 can be updated by the user with a simple Linux/Windows conﬁguration

program. The BDI3000 supports 1.2 – 5.0 Volts target systems.
