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.
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
■
Write a binary file to flash memory
■
Load the contents of the flash memory into a file
c
Do not exit from the control panel while erasing the flash
memory.
