uImage /dev/mtdblock1 (0x00020000~0x00400000)

4MB arrangement excluding head 128KB

initrd ----- (Not use)
rootfs /dev/mtdblock2

u-boot environment variable settings

setenv default_kernel_addr 0x00100000 
setenv bootargs_base console=ttyS0,115200 
setenv bootargs_root root=/dev/mtdblock2 rw 
setenv bootargs $(bootargs_base) $(bootargs_root) $(buffalo_ver) 
setenv uImage_block 0 
setenv uImage_offset 0x00020000 
setenv bootcmd ‘nboot $(default_kernel_addr) $(uImage_block) $(uImage_offset); bootm $(default_kernel_addr)’ 

Boot settings when uImage(nand /dev/mtdblock1), rootfs(/dev/sda2)

uImage /dev/mtdblock1 (0x00020000~0x00400000)

4MB arrangement excluding head 128KB

initrd -----(Not use)
rootfs /dev/sda2

u-boot environment settings

setenv default_kernel_addr 0x00100000 
setenv bootargs_base console=ttyS0,115200 
setenv bootargs_root root=/dev/sda2 rw

setenv bootcmd ‘nboot $(default_kernel_addr) $(uImage_block) $(uImage_offset); bootm $(default_kernel_addr)’

Boot settings when uImage(/dev/sda1), rootfs(/dev/sda2)

uImage /dev/sda1
initrd -----(Not use)
rootfs /dev/sda2
Notes
  • /dev/sdal is formatted in ext2, and uImage.buffalo is stored.

setenv bootargs_base console=ttyS0,115200 
setenv bootargs_root root=/dev/sda2 rw 
setenv bootargs $(bootargs_base) $(bootargs_root) $(buffalo_ver) 
setenv bootcmd ‘ext2load ide 0:1 $(default_kernel_addr)/$(kernel); bootm $(default_kernel_addr)’ 

Boot settings when uImage(tftp load), rootfs(nand /dev/mtdblock2)

uImage Load from tftp
initrd -----(Not use)
rootfs /dev/mtdblock2
tftpserver (e.g.) 192.168.11.100
KUROBOX-PRO (e.g.) 192.168.11.150
Notes
  • uImage.buffalo exists in the tftp root directory of tftpserver.

setenv bootcmd ‘tftp $(default_kernel_addr) $(kernel); bootm $(default_kernel_addr)

Boot settings when uImage(tftp load), initrd(tftp load)

uImage Load from tftp
initrd Load from tftp
rootfs Exists in initrd
tftpserver (e.g.) 192.168.11.100
KUROBOX-PRO (e.g.) 192.168.11.150
Notes
  • uImage.buffalo and initrd.buffalo exist in the tftp root directory of tftpserver.
  • rootfs exists in initrd.
  • After expanding rootfs in initrd, it is within 32MB.
