In this exercise, you
To start VisualDSP++ and open a project
1. Click the Windows Start button and select Programs, Analog Devices, VisualDSP++ 4.5, and VisualDSP++ Environment.
2. From the File menu, choose Open and then Project. VisualDSP++ displays the Open Project dialog box.
3. In the Look in box, open the UART Project given in the CD Example codes
Project Loaded in the Project Window
This dialog box enables you to specify project build information.
9. Take a moment to view the various pages in the Project Options dialog box by selecting them from the tree on the left: Project, General, Compile, Assemble, Link, Load, Pre-Build, and Post-Build. On each page, you specify the tool options used to build the project.
Click the LOAD tab to display the General page, shown in Figure
choose boot mode as flash/ PROM, Boot Format as Intel ASCII and Output width as 16 bit.
Choose a folder for an output file
After changing the options again Rebuild All
Loader file will be generated in the folder mentioned in the project options
Now the generated Loader file should be loaded into the Flash memory by using Blackfin Flash programmer
Make Sure that the Board is in Programming Mode, By Placing Jumpers at Proper Places In Programming Mode we should not connect any jumper to J1 and J2. The JUMPERS Should be there in J8 and WP and SSEL Should be Configured for BF532 i.e. The JUMPER should be there in the BF532 Side Now Actually BF532 Booting in “11“ mode i.e. Booting From SPI Flash for boot modes refer BF532 Hardware reference manual
Note : Connect a Direct (1-1) Serial Cable to the Kit from PC
Before the device can be used the settings required to make a connection must be specified.
Select the desired COM port from the drop down list or type the desired COM port directly into the box. If you enter the COM port yourself then you must enter it in one of the following formats.
Note: The Baud rate 115200 is to be selected for faster Loading of Larger Loader files. Note: Don’t Change Stop Bits and Data Bits, they are fixed in the code
Port name COM1
Baud Rate 9600
Stop bits 1
Data bits 8
Port connected successfully will be displayed in output window
If it the port is not connected .The following message will display…
Ensure the kit is in proper mode and Press the RESET button in the Kit and try again..
Press the erase button
Click ok to continue
After erasing the following message will be displayed in output window Note: Erase will take some time, based on the Flash Content. Worst Case Full Flash Erase time is around 120sec.Typical Timing is 30sec
Select the file by using browse button. The progress bar will show you the memory occupied and the file contents, file size and checksum will be displayed in status window.
Note: For Every Loader file, Checking in Status Window is Difficult; Checksum is the one that needs to check.
Click program to program the device
After Successfully programming the Loader file , the Board should be configured to general Mode for running the loader file.
In general mode a jumper must be connected to J1 as given in 5th chapter.
Previously whatever are there in the ”Programming Mode” keep all Additionally just we need to put the JUMPER in J1 or BMODE1 in “C” side Now the Boot Mode is changed to “01 ” where it will Boot from 8-bit/16-bit Flash
Now open the HYPERTERMINAL Application as shown below
RESET the Kit again (After Changing Hardware settings) You can See as shown
Type ‘@’ From Keyboard
Now Press any key DSP will Echo that key
UART DEMO is Completed
