1.user版本使用adb

打开文件

build/make/core/main.mk

  ifeq ($(user_variant),user)ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=0endif

1.这个ro.adb.secure=0（0为不显示信任此电脑，1为显示信任此电脑）

ifeq (true,$(strip $(enable_target_debugging)))# Target is more debuggable and adbd is on by defaultADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1# Enable Dalvik lock contention logging.ADDITIONAL_BUILD_PROPERTIES += dalvik.vm.lockprof.threshold=500
else # !enable_target_debugging# Target is less debuggable and adbd is off by defaultADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0
endif # !enable_target_debugging

2.adb文件传输

获取root权限

adb root
adb disable-verity
adb reboot
adb root
adb remount
adb shell
mount -o rw,remount /system

如果权限不对，可能会上传失败

上传文件：adb push 123.txt /system

下载文件：adb pull /system/123.txt ./

3.No module named Crypto.Signature

编译源码报错

  File "/root/SPRD/H6B-1/SC200K_Android10.0_R01_W21.21.1/vendor/sprd/proprietories-source/packimage_scripts/signimage/dynamicTA/signta.py", line 31, in mainfrom Crypto.Signature import PKCS1_v1_5
ImportError: No module named Crypto.Signature
12:26:45 ninja failed with: exit status 1#### failed to build some targets (08:00:14 (hh:mm:ss)) ####

需要安装

sudo apt-get install python-pip

sudo pip2 install pycrypto

4.插USB会自动开机

路径：bsp\bootloader\u-boot15\common\cmd_cboot.c

更换如下内容

5.设备树增加按键节点，没有中断事件返回

修改

bsp/bootloader/u-boot15/board/spreadtrum/uis8581e5h10/pinmap-sp9863a.c

bsp/kernel/kernel4.14/arch/arm64/boot/dts/sprd/uis8581e5h10.dts

6.rocess will be UID/EUID=0 in the global user namespace, and will have user root-level access to files

报错内容为

ninja: build stopped: subcommand failed.

关键点不在报错上，往上查/bin/bash

解决方案

echo 'export PATH=$PATH:$HOME/bin' >> ~/.bashrc  
export PATH=$PATH:$HOME/bin
