5.2 Build STi5100 IPSTB Code
5.2.1 Location of Source Files
The relevant TSC and NexGen source files required to build and run the STi5100 video streaming
application example are listed below. The NexGen files include modifications to support the hardware
checksum.
TSC Source Files
• Directory path:
C:\ipstba5 \src\nexgen_drv
o
ether_tsc78q8430.c Wrapper file which include Teridian source files
o
tsccore.c Core code
o
tscport.c OS and H/W dependent code
o
tsctest.c Test application code
• Directory path: C:\ipstba5 \include
o
ether_tsc78q8430.h Wrapper file which include Teridian header files
o
tscport.h OS and H/W dependent headers
o
commem.h Common memory, data structure declaration
o
comregs.h Register declaration
NexGen Files with Hardware Checksum
• Directory path:
C:\ipstba5 \src\nexgen_drv
o
ipncs.c Enable HW checksum usage in IP files
o
udpncs.c Enable HW checksum usage in UDP files
o
tcpncs.c Enable HW checksum usage in TCP files
5.2.2 Build the Software
Use the following procedure to build the software:
STEP 1:
Use Windows File Manager to open a window.
STEP 2: Select the directory C:\ipstba5.
STEP 3: Double click to execute the ipstb_setup link. A blue DOS window will appear displaying:
Using 5100ref root: c:\ipstba5
c:\ipstba5
\src\ref_ipstb>
STEP 4:
Make the new Ethernet device driver and NexGen code (create nexgen_drv.lib).
▪ Change to directory C:\ipstba5\src\nexgen_drv.
▪ gmake clean
▪ gmake
