Initial Installation
RedBoot is installed using the code download facility built into the Atlas board. See the Atlas User manual for
details, and also the Atlas download format in the Section called Atlas download format.
Quick download instructions
Here are quick start instructions for downloading the prebuilt RedBoot image.
1. Locate the prebuilt files in the bin directory: deleteall.dl and redboot.dl.
2. Make sure switch S1-1 is OFF and switch S5-1 is ON. Reset the board and verify that the LED display reads
Flash DL.
3. Make sure your parallel port is connected to the 1284 port Of the Atlas board.
4. Send the deleteall.dl file to the parallel port to erase previous images:
$ cat deleteall.dl >/dev/lp0
When this is complete, the LED display should read Deleted.
5. Send the ROM mode RedBoot image to the board:
$ cat redboot.dl >/dev/lp0
When this is complete, the LED display should show the last address programmed. This will be something
like: 1fc17000.
6. Change switch S5-1 to OFF and reset the board. The LED display should read RedBoot.
7. Run the RedBoot fis init and fconfig commands to initialize the flash. See the Section called Additional config
options, the Section called Flash Image System (FIS) in Chapter 2 and the Section called Persistent State
Flash-based Configuration and Control in Chapter 2 for details.
Atlas download format
In order to download RedBoot to the Atlas board, it must be converted to the Atlas download format. There are
different ways of doing this depending on which version of the developer’s kit is shipped with the board.
