Additional Procedures A-5
A.3 Alternate Boot Methods
The default configuration for the EVM is to boot from flash with the file
system on the EVM’s hard drive. The following are alternate ways you
may want to boot the board:
❏
TFTP boot with hard drive file system (Section A.3.2)
❏
Flash boot with NFS file system (Section A.3.3)
❏
TFTP boot with NFS file system (Section A.3.4)
The subsections that follow show the environment variable settings used
to enable each boot method.
Note: Using video files from an NFS file system may result in a low
frame rate when encoding/decoding videos.
To boot in one of these modes, follow these steps:
1) Power on the EVM board, and abort the automatic boot sequence by
pressing a key in the console window (Section 2.2).
2) Set the environment variables indicated in the following subsections
for the boot mode you want to use. (Note that the
setenv bootargs
command should be typed on a single line.)
3) If you want to use these settings as the default in the future, save the
environment:
EVM # saveenv
4) Boot the board using the settings you have made:
EVM # boot
A.3.1 Booting from Flash Using the EVM’s Hard Drive File System
This is the default, out-of-the-box boot configuration.
To boot in this mode, set the following parameters after you abort the
automatic boot sequence:
EVM # setenv bootcmd 'nboot 80700000 0 a0000;bootm'
EVM # setenv bootargs mem=120M console=ttyS0,115200n8
