Preliminary

The software design uses the MicroC/OS-II operating system. All stdout, stdin, and

stderr messages are directed to the jtag_uart. You use the auto-generated linker script

to store the heap linker section in DDR SDRAM memory and the other linker

sections—program memory, read-only data memory, read/write data memory, and

stack—in SSRAM memory.

6. Click OK.

Specify the Zip File System Settings

The tutorial software application project manipulates stored JPEG images. These

JPEG images are stored in the CFI flash memory on the NEEK. The project uses the

Altera read-only zip file system to store and access the JPEG images in flash memory.

To use the read-only zip file system, you must ensure that the JPEG image files are

zipped in a single file in uncompressed mode. The tutorial design files include a

prezipped, uncompressed file that contains the JPEG image files.

To add the Altera read-only zip file system and set up your project to store the

prezipped JPEG images to the NEEK flash memory, perform the following steps:

1. In Windows Explorer, open the images folder in your working directory. The list

of files in this folder includes the jpeg_images.zip file.

2. To copy the images to your project, drag and drop jpeg_images.zip on the

neek_picture_viewer_syslib folder in the Nios II IDE.

3. Right-click neek_picture_viewer_syslib.

4. Click Properties.

5. In the left pane, click System Library. The System Library dialog box appears.

6. Click Software Components. The Software Components dialog box appears.
