I. Root FileSystem/IP Configuration

bootcmd=tftp 100000 vmlinux.img;bootm
bootdelay=3
baudrate=9600
ipaddr=<IP ADDRESS>
netmask=<NETMASK>
hostname=<NAME>
serverip=<NFS SERVER IP ADDRESS>
ethaddr=00:00:10:20:30:44
nfsroot=<NFS SERVER IP ADDRESS>:/boot/root-fs
gateway=<IP ADDRESS>
root=/dev/nfs
stdin=serial
stdout=serial
stderr=serial

NVRAM environment variables.

use the command:

setenv <attribute> <value>

type "saveenv" to write to NVRAM.


II. To boot from a hard drive:

setenv root /dev/hda1


III. IP options which configure the network:

ipaddr=<IP ADDRESS OF MACHINE>
netmask=<NETMASK>
hostname=mousse
ethaddr=00:00:10:20:30:44
gateway=<IP ADDRESS OF GATEWAY/ROUTER>


IV. IP Options which configure NFS Root/Boot Support

root=/dev/nfs
serverip=<NFS SERVER IP ADDRESS>
nfsroot=<NFS SERVER IP ADDRESS>:/boot/root-fs

V. U-Boot Image Support

The U-Boot boot loader assumes that after you build
your kernel (vmlinux), you will create a U-Boot image
using the following commands or script:

#!/bin/csh
/bin/touch vmlinux.img
/bin/rm vmlinux.img
set path=($TOOLBASE/bin $path)
set path=($U_BOOT/tools $path)
powerpc-linux-objcopy -S -O binary vmlinux vmlinux.bin
gzip -vf vmlinux.bin
mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -n vmlinux.bin.gz -d vmlinux.bin.gz vmlinux.img
ls -l vmlinux.img


VI. ONBOARD FLASH Support

FLASH support is provided for the onboard FLASH chip Bootrom area.
U-Boot is loaded into either the ROM boot region of the FLASH chip,
after first being boot-strapped from a pre-progammed AMD29F040 PLCC
bootrom. The PLCC needs to be programmed with a ROM burner using
AMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record)
images.

The PLCC overlays this same region of flash as the onboard FLASH,
the jumper J100 is a chip-select for which flash chip you want to
progam. When jumper J100 is connected to pins 2-3, you boot from
PLCC FLASH.

To bringup a system, simply flash a flash an AMD29F040 PLCC
bootrom, and put this in the PLCC socket. Move jumper J100 to
pins 2-3 and boot from the PLCC.


Now, while the system is running, move Jumper J100 to
pins 1-2 and follow the procedure below to FLASH a bootrom
(u-boot.bin) image into the onboard bootrom region (AMD29LV160DB):

tftp 100000 u-boot.bin
protect off FFF00000 FFF7FFFF
erase FFF00000 FFF7FFFF
cp.b 100000 FFF00000 \${filesize}\


Here is an example:

=>tftp 100000 u-boot.bin
eth_halt
eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0)
DEC Ethernet iobase=0x80000000
ARP broadcast 1
Filename 'u-boot.bin'.

=>erase FFF00000 FFF7FFFF
Erase Flash from 0xfff00000 to 0xfff7ffff
Erase FLASH[PLCC_BOOT] -8 sectors:........ done
Erased 8 sectors
=>cp.b 100000 FFF00000 1e154
Copy to Flash... FLASH[PLCC_BOOT]:..done
=>


B. FLASH RAMDISK REGION

FLASH support is provided for an Onboard 512K RAMDISK region.

TThe following commands will FLASH a bootrom (u-boot.bin) image
into the onboard FLASH region (AMD29LV160DB 2MB FLASH):

tftp 100000 u-boot.bin
protect off FFF80000 FFFFFFFF
erase FFF80000 FFFFFFFF
cp.b 100000 FFF80000 \${filesize}\


C. FLASH KERNEL REGION (960KB)

FLASH support is provided for the 960KB onboard FLASH1 segment.
This allows flashing of kernel images which U-Boot can load
and run (standalone) from the onboard FLASH chip. It also assumes

The following commands will FLASH a kernel image to 0xffe10000

tftp 100000 vmlinux.img
protect off FFE10000 FFEFFFFF
erase FFE10000 FFEFFFFF
cp.b 100000 FFE10000 \${filesize}\
reset

Here is an example:


=>tftp 100000 vmlinux.img
eth_halt
eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0)
DEC Ethernet iobase=0x80000000

Bytes transferred = 760231 (b99a7 hex)

=>protect off FFE10000 FFEFFFFF
Un-Protected 15 sectors
=>erase FFE10000 FFEFFFFF
Erase Flash from 0xffe10000 to 0xffefffff
Erase FLASH[F0_SA3(KERNEL)] -15 sectors:............... done
Erased 15 sectors
=>cp.b 100000 FFE10000 b99a7
Copy to Flash... FLASH[F0_SA3(KERNEL)]:............done
=>


When finished, use the command:

bootm ffe10000

to start the kernel.

Finally, to make this the default boot command, use
the following commands:

setenv bootcmd bootm ffe10000
savenv

to make it automatically boot the kernel from FLASH.


To go back to development mode (NFS boot)

setenv bootcmd tftp 100000 vmlinux.img\;bootm
savenv
