Lab 2b: DSP/BIOS Configuration Tool
Lab2.pjt from the Project Recent Project Files list. This will put you
at the proper starting point for this lab exercise.
2. If needed, verify that the project is open in CCS by left clicking the plus sign (+) to the
left of Project. Then, click on the plus sign next to Lab2.pjt ,as well as the other
plus signs to verify all the previous files have been included.
Remove “rts2800_ml.lib” and “Lab2a.cmd” from the Project
3. Highlight the rts2800_ml.lib in the project window and right click, then select
“Remove from Project”. The DSP/BIOS Config Tool supplies its own rts library.
4. Remove Lab2a.cmd using the same procedure. We will be using the DSP/BIOS
configuration tool to create a linker command file.
Using the DSP/BIOS Configuration Tool
5. The configuration database files (*.cdb), created by the Config Tool, controls a wide
range of CCS capabilities. In this lab exercise, the CDB file will be used to automatically
create and perform memory management. Create a new CDB file for this lab. On the
menu bar click:
File New DSP/BIOS Configuration…
A dialog box appears. The CDB files shown in the aforementioned dialog box are called
“seed” CDB files. CDB files are used to configure many objects specific to the
processor. Select the c28xx.cdb template and click OK.
6. Save the configuration file by selecting:
File Save As…
and name it Lab.cdb in C:\C28x\LABS\LAB2. Close the configuration window.
7. Add the configuration file to the project. Click:
Project Add Files to Project…
Make sure you’re looking in C:\C28x\LABS\LAB2. Change the “files of type” to
view All Files (*.*) and select Lab.cdb. Click OPEN to add the file to the project.
8. Add the generated linker command file, Labcfg.cmd, to the project using the same
procedure.
Create New Memory Sections Using the CDB File
9. Open the Lab.cdb file by left clicking on the plus sign (+) to the left of DSP/BIOS
Config and double clicking on the Lab.cdb file. In the configuration window, left
click the plus sign next to System and the plus sign next to MEM.
10. By default, the Memory Section Manager has combined the memory space for
L0SARAM and L1SARAM into a single memory block called L0SARAM. It has also
