|
|
|
|
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
|
|
|
|
|
|

|
|
|
|

|
|
netmask=<NETMASK>
|
|
hostname=mousse
|
|

|
|
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
|
|

|
|
|
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
|
|

|
|

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
