Booting the New Linux Kernel
After building the new kernel, in order to use it to boot the DaVinci board,
you must transfer it to the board via TFTP. It is assumed you have
completed the steps in Section 4.6,
and the
boot file, uImage has been copied to /tftpboot (or some other site-specific
TFTP accessible location).
1) Power on the DVEVM board, and abort the automatic boot sequence
by pressing a key in the console window (Section 2.2).
2) Set the following environment variables. (This assumes you are
starting from a default, clean U-Boot environment. See Section 3.1,
for information on the U-Boot default
environment.)
EVM # setenv bootcmd 'dhcp;bootm'
EVM # setenv serverip <
YOUR TFTP SERVER IP ADDRESS
>
EVM # setenv bootfile uImage
EVM # setenv bootargs mem=120M console=ttyS0,115200n8
root=/dev/hda1 rw noinitrd ip=dhcp
This configuration boots a new Linux kernel via TFTP with a hard drive
based file system. Please see Section A.5.4,
for information on using TFTP with an NFS file system.
