全志A10主板移植Linux

全志A10主板移植主线Uboot和Linux

背景

板子为小黄鱼上收到的一块全志A10的广告机主板，想对这张板子移植下最新的主线Uboot和Linux内核。

原始状态

Uboot

环境变量

boot_fastboot=fastboot
boot_normal=sunxi_flash read 40007800 boot;boota 40007800
boot_recovery=sunxi_flash read 40007800 recovery;boota 40007800
bootcmd=run setargs_nand boot_normal
bootdelay=1
console=ttyS0,115200
init=/init
loglevel=5
mac=00:00:00:00:00:00
mmc_root=/dev/mmcblk0p7
nand_root=/dev/nandd
partitions=bootloader@nanda:env@nandb:boot@nandc:system@nandd:data@nande:misc@nandf:recovery@nandg:cache@nandh:private@nandi:sysrecovery@nandj:UDISK@nandk
setargs_mmc=setenv bootargs console=${console} root=${mmc_root} init=${init} loglevel=${loglevel} mac_addr=${mac} partitions=${partitions}
setargs_nand=setenv bootargs console=${console} root=${nand_root} init=${init} loglevel=${loglevel} mac_addr=${mac} partitions=${partitions}
stderr=serial
stdin=serial
stdout=serial

移植Uboot

  1. 使用configs/A10-OLinuXino-Lime_defconfig，默认配置，修改设备树sun4i-a10-olinuxino-lime.dts

  2. 编译得到u-boot-sunxi-with-spl.bin，烧写到SD卡8k偏移处

    dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1k seek=8

  3. 插入SD卡，上电打印

移植Linux

  1. 使用arch/arm/configs/sunxi_defconfig默认配置

  2. 设备树
