2.1.1 Changing Target Processor Type

Before you can use the BDI2000 with an other target processor type (e.g. ARM <--> PPC), a new setup has to be done (see chapter 2.5). During this process the target cable must be disconnected from the target system. The BDI2000 needs to be supplied with 5 Volts via the BDI OPTION connec- tor (Rev. A) or via the POWER connector (Rev. B/C). For more information see chapter 2.2.1 «External Power Supply»).

!

To avoid data line conflicts, the BDI2000 must be disconnected from the target system while programming the logic for an other target CPU.
