79 III. IP options which configure the network:

84 ethaddr=00:00:10:20:30:44
85 gateway=<IP ADDRESS OF GATEWAY/ROUTER>
88 IV. IP Options which configure NFS Root/Boot Support
91 serverip=<NFS SERVER IP ADDRESS>
92 nfsroot=<NFS SERVER IP ADDRESS>:/boot/root-fs
94 V. U-Boot Image Support
96 The U-Boot boot loader assumes that after you build
97 your kernel (vmlinux), you will create a U-Boot image
98 using the following commands or script:
101 /bin/touch vmlinux.img
103 set path=($TOOLBASE/bin $path)
104 set path=($U_BOOT/tools $path)
105 powerpc-linux-objcopy -S -O binary vmlinux vmlinux.bin
107 mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -n vmlinux.bin.gz -d vmlinux.bin.gz vmlinux.img
111 VI. ONBOARD FLASH Support
113 FLASH support is provided for the onboard FLASH chip Bootrom area.
114 U-Boot is loaded into either the ROM boot region of the FLASH chip,
115 after first being boot-strapped from a pre-progammed AMD29F040 PLCC
116 bootrom. The PLCC needs to be programmed with a ROM burner using
117 AMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record)
120 The PLCC overlays this same region of flash as the onboard FLASH,
121 the jumper J100 is a chip-select for which flash chip you want to
122 progam. When jumper J100 is connected to pins 2-3, you boot from
125 To bringup a system, simply flash a flash an AMD29F040 PLCC
126 bootrom, and put this in the PLCC socket. Move jumper J100 to
127 pins 2-3 and boot from the PLCC.
130 Now, while the system is running, move Jumper J100 to
131 pins 1-2 and follow the procedure below to FLASH a bootrom
132 (u-boot.bin) image into the onboard bootrom region (AMD29LV160DB):
134 tftp 100000 u-boot.bin
135 protect off FFF00000 FFF7FFFF
136 erase FFF00000 FFF7FFFF

164 B. FLASH RAMDISK REGION
166 FLASH support is provided for an Onboard 512K RAMDISK region.
168 TThe following commands will FLASH a bootrom (u-boot.bin) image
169 into the onboard FLASH region (AMD29LV160DB 2MB FLASH):
171 tftp 100000 u-boot.bin
172 protect off FFF80000 FFFFFFFF
173 erase FFF80000 FFFFFFFF
174 cp.b 100000 FFF80000 \$(filesize)\
178 C. FLASH KERNEL REGION (960KB)
180 FLASH support is provided for the 960KB onboard FLASH1 segment.
181 This allows flashing of kernel images which U-Boot can load
182 and run (standalone) from the onboard FLASH chip. It also assumes
184 The following commands will FLASH a kernel image to 0xffe10000
186 tftp 100000 vmlinux.img
187 protect off FFE10000 FFEFFFFF
188 erase FFE10000 FFEFFFFF
