5 STi5100 IPSTB Platform Example
The STi5100 IPSTB demonstrates the 78Q8430 Ethernet driver capability in an internet streaming video
application. This section describes how to set up the platform, build the driver and NexGen software, and
run an example which plays and stops an MPEG2 movie.
Figure 13 shows the components and
connections for the STi5100 IPSTB platform. Refer to the 78Q8430 STEM Demo Board User Manual for
additional information on the hardware setup.

5.1 Setup
The path names (in italics) given in the following steps are for illustrative purposes. If the software has
been installed in different directories than those given below, replace the path in the example with the
appropriate path for your installation.
5.1.1 Host PC Environment
Changes to the PC environment are needed when using the STi5100 platform or when changing between
the STi5100 and STi5514 platforms. The STi5514 platform uses the old ST20R1.9.6 tool set while the
STi5100 platform uses the newer ST20R2.0.5 tool set. Use the following procedure to modify the
environment:
STEP 1:
Modify the Windows Environment to use the ST20R2.0.5 tool set.
Append C:\STM\ST20R2.0.5\bin; to the front of the system variable ‘Path’. As an example, the new path
might be C:\STM\ST20R2.0.5\bin;C:\STM\ST20R1.9.6\bin;%SystemRoot%\system32;……
STEP 2: Modify the system variable ‘ST20ROOT’ as follows:
ST20ROOT C:\STM\ ST20R2.0.5
STEP 3:
Reboot the PC.
