Using the Control Panel

Read from a File

To read the contents of a file and load it to the DDR SDRAM, follow these

steps:

1. Click Load File.

2. Browse to sample.txt located in the control_panel directory and

click Open. This step instantiates the DDR SDRAM controller and

loads the text contents into the DDR SDRAM. Notice that the Data

to Ascii-text column shows the DDR SDRAM contents in Ascii

value.

Write to a File

To write the contents of the DDR SDRAM to a file, follow these steps:

1. Click Save File.

2. Enter the start and end addresses of the DDR SDRAM.

3. Choose a file name and click Save. This instantiates the controller to

read the DDR SDRAM contents from the start address to the end

address, and write the contents to a file.

Flash Memory

Programmer

You can perform the following operations to read from and write to the

board’s flash memory with the control panel:

■ Perform a CFI query of flash memory

■ Erase select blocks of flash memory

■ Write 32-bit hex word to flash memory
