内核,uboot源代码有改动,Yocto如何修改?
答:当对内核或uboot进行修改了, 再在Yocto中构建时, 需要在Yocto 中修改内核或uboot的commit ID。
得到内核或uboot的commit ID:
在内核或uboot目录下:
git add . (提交所有的改变)
git config - -gobal user.email “your Email address”(提交修改者邮件)
git config - - global user.name “your name” (提交修改者名字)
git commit -m “comment”添加注释
git log (得到commit ID)
Yocto 中内核修改地址:
/home/roy/MYD-Y6ULX-devel/04-Source/fsl-release-Yocto/sources/meta-myir-imx6ulx/recipes-kernel/linux/linux-mys6ulx_4.1.15.bb 中的“SRCREV”
代码示例如下:
# Copyright (C) 2013-2016 Freescale Semiconductor
# Released under the MIT license (see COPYING.MIT for the terms)
SUMMARY = "Linux Kernel for MYiR MYS6ULx board"
DESCRIPTION = "Linux Kernel provided and supported by Freescale with focus on \
i.MX Family Reference Boards. It includes support for many IPs such as GPU, VPU and IPU."
require recipes-kernel/linux/linux-imx.inc
require recipes-kernel/linux/linux-dtb.inc
DEPENDS += "lzop-native bc-native"
LOCALVERSION = "-1.2.0"
SRCREV = "d87b5be6bfc5a78cd45d8efa044fddcd7f4b2ac1"
SRCBRANCH = "mys-6ulx"
SRC_URI = "git:///${HOME}/MYiR-iMX-Linux;protocol=file;branch=${SRCBRANCH} \
file://defconfig \
"
DEFAULT_PREFERENCE = "1"
COMPATIBLE_MACHINE = "(mx6ull|mx6ul)"
Yocto 中uboot 修改ID位置:
/home/roy/MYD-Y6ULX-devel/04-Source/fsl-release-Yocto/sources/meta-myir-imx6ulx/recipes-bsp/u-boot/u-boot-mys6ulx_2016.03.bb
