全志芯片 u-boot&kernel 机器ID位置

kernel/arch/arm/tools/mach-types     sun7i

vi u-boot/board/allwinner/sun7i-evb/sun7i-evb.c //这个是蜂鸟的SDK里的位置

/* add board specific code here */

int board_init(void) {

        gd->bd->bi_arch_number = 3893;

……

}

u-boot中要是没有上面的那个目录的话就看看

u-boot-sunxi$ grep -rn 4283 ./

./arch/powerpc/cpu/mpc8xx/upatch.c:119: 0xedf0cc87, 0xfb18ad0a, 0x1f85bbb8, 0x74283b7e,

./include/autoconf.mk:140:CONFIG_MACH_TYPE=4283

./include/spl-autoconf.mk:121:CONFIG_MACH_TYPE=4283

./include/configs/sun7i.h:19:#define CONFIG_MACH_TYPE           4283 //这个事全志u-boot的位置

//==================================================

在启动的u-boot中查看机器ID：

使用命令：bdinfo  - print Board Info structure

例如：

BananaPi> bdinfo

arch_number = 0x000010BB //0x000010BB就是机器ID

boot_params = 0x40000100

DRAM bank   = 0x00000000

-> start    = 0x40000000

-> size     = 0x40000000

eth0name    = dwmac.1c50000

ethaddr     = (not set)

current eth = dwmac.1c50000

ip_addr     = <NULL>

baudrate    = 115200 bps

TLB addr    = 0x7FFF0000

relocaddr   = 0x7FF86000

reloc off   = 0x35F86000

irq_sp      = 0x7FB65F40

sp start    = 0x7FB65F30
