Creating a Flash Image
CS4953x4/CS4970x4 System Designer’s Guide
13. To program the serial Flash connected to the DSP, the egg.img, flash.img may be copied to:
C:\Cirrus DSP\CS4953x\apps\<board_name>\sd\flash
Note: <board_name> can be "crd49500" or "ck49x_4953x4"
8.7.2.2 Making Snapshots of a Change
Perform the following steps to create several snapshots of changes in DSP Composer.
1. Make sure that the CS49x Board USB cable is plugged in.
2. Press the green Go button in DSP Composer. The Check and Compile window displays and closes,
and then the Deploying Project dialog box shows progress and closes when deployment is
complete.
3. Select the Compile Results tab at the bottom of DSP Composer.
4. Scroll down to see the results. You can see the message “Project compiled successfully” at the
bottom of the display.
5. On the DSP Composer Menu, select Tools > Snapshots. The Snapshots Manager Dialog Box
displays.
6. In DSP Composer, double-click the APP block in the DSP Composer project. The APP Panel
displays.
7. Select the Audio Manager tab. On the APP Panel, note that the Gain, the left-most control, is at +0
dB.
8. Press the New button on the Snapshot Dialog box. The New Snapshot Name dialog box appears.
9. Name the snapshot audio_mgr_0db and click OK.
10. Go back to the APP control panel and change the Gain to +10 dB. You should hear the volume
increase +10 dB.
11. On the Snapshot Manager Dialog Box, press the New button.
12. In the New Snapshot Name window, name the snapshot audio_mgr_plus10db.
13. Repeat steps 10–12 for –10 dB.
14. After you are finished creating snapshots, close the Snapshot window.
15. On the DSP Composer menu, select Tools > Generate Deliverables.
16. Save the Deliverables to the C:\CirrusDSP\DSPCondenser\deliverables directory.
17. Save the DSP Composer project.
18. Exit DSP Composer.
8.7.2.3 Integrating the Snapshots into the Flash Image
The names you give to your modes default to the snapshot name, but the mode can be renamed. The
mode names are used in the output of the Condenser project as C language #define statements as an aid
for the microprogrammer, allowing semantically meaningful names to be used in the microcode used to
control the DSP through the DSP Manager API.
Perform the following steps to integrate snapshots into the flash image as modes:
1. In DSP Condenser Wizard, use File > Open Project to open the CS497004_sample_licensed.7z
project.
2. Select the Prekick module modes > Audio Manager page.
