imx6 linux编译,IMX6学习记录(3)-LINUX编译
上面是我創(chuàng)建的群聊，歡迎新朋友的加入。

1.獲取官方kernel
2.編譯內(nèi)核
3.內(nèi)核燒錄
4.調(diào)整uboot
5.卡分區(qū)
1.獲取官方kernel
地址：http://git.freescale.com/git/cgit.cgi/imx/linux-imx.git/tag/?h=imx_4.1.15_2.0.0_ga&id=rel_imx_4.1.15_2.1.0_ga
拉到最后，先把源碼搞下來
2.編譯內(nèi)核
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- imx_v7_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- all -j4
不知道怎么回事，上來編譯就報(bào)錯(cuò)了

jun@ubuntu:~/i.mx6/source/linux$ ls -la
解決辦法
sudo apt install dos2unix
dos2unix ./scripts/gcc-goto.sh
dos2unix ./scripts/gcc-version.sh
dos2unix ./scripts/link-vmlinux.sh
3.內(nèi)核燒錄
找到編譯出來的文件
其中zimage就是內(nèi)核固件，燒錄的就是它，一個(gè)6M的文件
按照官方指導(dǎo)，通過DD燒錄到SD卡
搞完內(nèi)核。還有一個(gè)設(shè)備樹也要捎進(jìn)去
4.調(diào)整uboot
啟動(dòng)是啟動(dòng)了，但是這不是我剛剛編譯出來的
將uboot的頭文件按照燒錄的地址設(shè)置啟動(dòng)位置

現(xiàn)在還是沒跑起來
將之前yocto的鏡像下載一遍，替換掉uboot、zimage和設(shè)備樹
現(xiàn)在是可以進(jìn)linux的，但是沒有正常跑起來，內(nèi)核是今天編譯出來的
5.卡分區(qū)
現(xiàn)在跑起來是因?yàn)槲蚁认螺d了一個(gè)yocto出來的鏡像，對卡進(jìn)行了分區(qū)。
如果沒得鏡像，那這個(gè)uboot和kernel就不能正常用了
從SD卡讀zimage和設(shè)備樹是要文件系統(tǒng)的
嘗試自行劃分一個(gè)分區(qū)出來
首先對照官方出來的卡狀態(tài)
98
總共兩分區(qū)，按理說只要和這個(gè)分區(qū)一樣，uboot就可以找到內(nèi)核鏡像和設(shè)備樹，以及文件系統(tǒng)了
首先格式化整個(gè)卡片
開始分配第一個(gè)分區(qū)，最小是16M，分不出8M。
第二個(gè)分區(qū)
整個(gè)盤
為了確定改動(dòng)是有效的，將內(nèi)核和uboot都全編譯一次
時(shí)間戳
首先寫入uboot
拷貝zimage和設(shè)備樹進(jìn)boot盤
文件系統(tǒng)先空著不管他
查看終端打印信息
其中uboot是U-Boot 2016.03 (Oct 23 2019 - 15:52:59 +0800)
kernel是：Oct 23 15:56:44 CST 2019
說明是正常從uboot跳轉(zhuǎn)到了kernel
