Alternate Boot Methods
A-6
A.3.2 Booting via TFTP Using the EVM’s Hard Drive File System
To boot in this mode, set the following parameters after you abort the
automatic boot sequence:
EVM # setenv bootcmd 'dhcp;bootm'
EVM # setenv bootargs mem=120M console=ttyS0,115200n8
root=/dev/hda1 rw noinitrd ip=dhcp
davincihd_capture.channel0_numbuffers=4
EVM # setenv serverip < tftp server ip address >
EVM # setenv bootfile < path on tftpserver >/uImage
A.3.3 Booting from Flash Using NFS File System
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 nfshost < ip address of nfs host >
EVM # setenv rootpath < directory to mount* >
EVM # setenv bootargs console=ttyS0,115200n8 noinitrd rw
ip=dhcp root=/dev/nfs
nfsroot=$(nfshost):$(rootpath),nolock mem=120M
davincihd_capture.channel0_numbuffers=4
*For example,
< directory to mount >
might be
/home/< useracct >/workdir/filesys
.
A.3.4 Booting via TFTP Using NFS File System
To boot in this mode, set the following parameters after you abort the
automatic boot sequence:
EVM # setenv bootcmd 'dhcp;bootm'
EVM # setenv serverip < tftp server ip address >
EVM # setenv bootfile < name of kernel image >
EVM # setenv rootpath < root directory to mount >
EVM # setenv nfshost < ip address of nfs host >
EVM # setenv bootargs console=ttyS0,115200n8 noinitrd rw
ip=dhcp root=/dev/nfs
nfsroot=$(nfshost):$(rootpath),nolock mem=120M
davincihd_capture.channel0_numbuffers=4
The < root directory to mount > must match the file system that you set up
on your workstation. For example, /home/< useracct >/workdir/filesys.
