A. 软件准备
user版本需要先打开USB debug开关,打开方式如下:
1、打开usb调试 build/core/main.mk
请将user版本下也改为ro.debuggable = 1
ifeq (true,(strip(enable_target_debugging)))
# Target is more debuggable and adbd is on by default
ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1
# Include the debugging/testing OTA keys in this build.
INCLUDE_TEST_OTA_KEYS := true
else # !enable_target_debugging
# Target is less debuggable and adbd is off by default
ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1 //这边改成1
endif # !enable_target_debugging
2、关闭授权框提示 device/sprd/scx35/device.mk
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)
打开后全编译版本
B. 硬件准备
需要飞线,找硬件从TX接线出来,飞线成功后用SecureCRT工具抓取uart log
配置方法参考:
首先安装SecureCRT软件和相对应的工具,之后打开SecureCRT,点击file–>Quick Connect
相关设置项如下:
Protocol 为Serial
Port 为计算机中的端口:比如COM23
Baud rate 要选为115200
Data bits 为8
Parity 为None
Stop bits 为1
Show quick connect on star 不勾选
其余均为默认
点击connect 就可以连接了
