【TINY4412】LINUX移植筆記：（15）SD卡啟動Linux核心
主控端 ： 虛拟機 Ubuntu 16.04 LTS / X64
目标闆[底闆]： Tiny4412SDK - 1506
目标闆[核心闆]： Tiny4412 - 1412
LINUX核心： 4.12.0

簡介
本節的目的就是要制作一張
SD
卡，用來啟動
U-BOOT
、
LINUX
、挂載
根檔案系統
，
SD
至少包含一個
FAT32
分區用于移動、替換、儲存源檔案。 還有一個
EXT4
分區用于加載放置
根檔案系統
。
思路：在
Linux
中，使用腳本
mk_uboot.sh
源檔案，啟動
u-boot
，
u-boot
啟動後通過
bootcmd
自動加載
linux核心
和
裝置樹
。核心啟動後自動加載
根檔案系統
運作
linux
。
源檔案
[email protected]:/opt/temp/temp# ls
E4412_N.bl1.bin exynos4412-tiny4412.dtb tiny4412-spl.bin
E4412_tzsw.bin rootfs.tar.gz u-boot.bin uImage
将
exynos4412-tiny4412.dtb
uImage
存儲到
SD卡
的
FAT32
分區，最簡單的辦法就是用讀卡器插到電腦端，拷貝。
燒錄u-boot
将
E4412_N.bl1.bin
tiny4412-spl.bin
u-boot.bin
E4412_tzsw.bin
燒錄到
SD卡
的指定位置，寫一個腳本
mk_uboot.sh
執行燒錄：

根檔案系統
流程：将
SD
卡到電腦端，通過虛拟機的
Linux
識别為裝置，然後挂載
SD
卡的
EXT4
檔案系統，将根檔案系統拷貝到該分區。
