The CompactFlash(R) controller on the Korat board provides a hi-speed USB

interface. This may be connected to either a dedicated port on the on-board
|

USB controller, or to a USB port on the PowerPC 440EPx processor. The U-Boot

5. Bring up two cores separately:
|
||||
|
||||
a. Power on the board, under u-boot prompt:
|
||||
=> setenv <serverip>
|
||||
=> setenv <ipaddr>
|
||||
=> setenv bootargs root=/dev/ram rw console=ttyS0,115200
|
||||
b. Bring up core1's kernel first:
|
||||
=> setenv bootm_low 0x20000000
|
||||
=> setenv bootm_size 0x10000000
|
||||
=> tftp 21000000 8572/uImage.core1
|
||||
=> tftp 22000000 8572/ramdiskfile
|
||||
=> tftp 20c00000 8572/mpc8572ds_core1.dtb
|
||||
=> interrupts off
|
||||
=> bootm start 21000000 22000000 20c00000
|
||||
=> bootm loados
|
||||
=> bootm ramdisk
|
||||
=> bootm fdt
|
||||
=> fdt boardsetup
|
||||
=> fdt chosen $initrd_start $initrd_end
|
||||
=> bootm prep
|
||||
=> cpu 1 release $bootm_low - $fdtaddr -
|
||||
c. Bring up core0's kernel(on the same u-boot console):
|
||||
=> setenv bootm_low 0
|
||||
=> setenv bootm_size 0x20000000
|
||||
=> tftp 1000000 8572/uImage.core0
|
||||
=> tftp 2000000 8572/ramdiskfile
|
||||
=> tftp c00000 8572/mpc8572ds_core0.dtb
|
||||
=> bootm 1000000 2000000 c00000
|
||||
a. Power on the board, under u-boot prompt:
|
||||
=> setenv <serverip>
|
||||
=> setenv <ipaddr>
|

=> setenv bootargs root=/dev/ram rw console=ttyS0,115200
|

b. Bring up core1's kernel first:

|
||||
=> tftp 22000000 8572/ramdiskfile
|
||||
=> tftp 20c00000 8572/mpc8572ds_core1.dtb
|
||||
=> interrupts off
|
||||
=> bootm start 21000000 22000000 20c00000
|
||||
=> bootm loados
|
||||
=> bootm ramdisk
|
||||
=> bootm fdt
|
||||
=> fdt boardsetup
|
||||
=> fdt chosen $initrd_start $initrd_end
|
||||
=> bootm prep
|
||||
=> cpu 1 release $bootm_low - $fdtaddr -
|
||||
c. Bring up core0's kernel(on the same u-boot console):
|
||||
=> setenv bootm_low 0
|
||||
=> setenv bootm_size 0x20000000

=> tftp 1000000 8572/uImage.core0

=> tftp c00000 8572/mpc8572ds_core0.dtb
|
||||
=> bootm 1000000 2000000 c00000
|
||||
|
||||
Please note only core0 will run u-boot, core1 starts kernel directly after
|
||||
"cpu release" command is issued.
