git系列------如何升级fw（测试专用）

  最近怀疑bug是由于fw太旧的问题，所以就升级一下fw作为测试

首先git clone下载fw

然后到vendor/qcom/proprietary目录下做patch，git log找到第一条提交

commit 6e60d7404fd375f9eca2c79a0a0e4ff76ed4cb06
Author: matthew_xuan
Date:   Wed Dec 21 15:19:50 2016 +0800


    init
    
    Signed-off-by: matthew_xuan

然后git format-patch -s efc594e56b60192bd4e6c30871021842319afc62把这条提交之后的提交都给做成patch

然后到fw所在文件夹下的spf2.0-r05000.1.75484.1/qcom_firmware/LA.UM.5.6/LINUX/android/vendor/qcom目录下准备打patch

结果

When you have resolved this problem run "git am --resolved".
If you would prefer to skip this patch, instead run "git am --skip".
To restore the original branch and stop patching run "git am --abort".

很明显出错了，原因在于patch里修改的文件的路径其实和fw这边的git不是同一个，也就是起始目录不同，所以只能在

qcom目录下

git init


git add -A


git commit -s -m "init"

新建git然后打上第一个git log

然后在git apply --reject patch名直接打即可
