Detailed Description
R
CPU JTAG Header Pinout
Figure 1-8
shows J12, the 16-pin header that can be used to debug the software operating in
the CPU with debug tools such as Parallel Cable IV or third party tools.
CPU JTAG Connection to FPGA
The connections between the CPU JTAG header (J12) and the FPGA are shown in
Table 1-22
. These are attached to the PowerPC® 440 processor JTAG debug resources
using normal FPGA routing resources. The JTAG debug resources are not hard-wired to
particular pins and are available for attachment in the FPGA fabric, making it possible to
route these signals to the preferred FPGA pins.
