"On" == 0
SW18 is switch 18 as silk-screened onto the board.
- SW4[8] is the bit labled 8 on Switch 4.
+ SW4[8] is the bit labeled 8 on Switch 4.
SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2
SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3
SW7[1:4] = 0101 = 5 => 5 x 66 = 330 CCB Sysclk
SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock
+ In order to use PCI-X (only in the first PCI slot. The one with
+ the RIO connector), you need to set SW1[4] (config) to 1 (off).
+ Also, configure the board to run PCI at 66 MHz.
2. MEMORY MAP TO WORK WITH LINUX KERNEL
2.1. For the initial bringup, we adopted a consistent memory scheme
- between u-boot and linux kernel, you can customize it based on your
+ between U-Boot and linux kernel, you can customize it based on your
system requirements:
0x0000_0000 0x7fff_ffff DDR 2G
kernel's ppcboot.h is consistent with U-Boot's u-boot.h. You can use two
default configuration files as your starting points to configure the
kernel:
- arch/ppc/configs/mpc8540_ads_defconfig
- arch/ppc/configs/mpc8560_ads_defconfig
+ arch/powerpc/configs/mpc8540_ads_defconfig
+ arch/powerpc/configs/mpc8560_ads_defconfig
