2.1 Connecting the BDI3000 to Target
The enclosed target cable is designed for the Intel recommended 20pin JTAG connector. In case
where the target system has an appropriate connector, the cable can be directly connected. The pin
assignment is in accordance with the Intel specification.
In order to ensure reliable operation of the BDI (EMC, runtimes, etc.) the target cable length must not
exceed 20 cm (8").
For BDI TARGET B connector signals see table on next page.
Warning:
Before you can use the BDI3000 with an other target processor type (e.g. PPC <--> ARM), a new
setup has to be done (see chapter 2.5). During this process the target cable must be disconnected
from the target system.
To avoid data line conflicts, the BDI3000 must be disconnected from the target system while
programming a new firmware for an other target CPU.
