pixel4 xl debug记录

烧写需要哪些image:
boot
dtbo
vbmeta
vbmeta_system
super_empty

进入fastbootd 模式
product system vendor

1, 单独运行boot.img
adb reboot bootloader
fastboot boot boot.img
2,打包左右的image 为update.zip
进行脚本的烧写

下面是调试信息：
1, 全部提换kernel out, 修改just status=okay
wifi 不能使用，touch 不能使用，屏幕正常显示

2， 全部提换kernel out, 修改如掉dp connector 修改
烧录不进去，屏幕黑屏
Writing 'vbmeta_a' OKAY [ 0.071s]
extracting vbmeta_system.img (0 MB) to disk... took 0.001s
archive does not contain 'vbmeta_system.sig'
Sending 'vbmeta_system_a' (4 KB) OKAY [ 0.138s]
Writing 'vbmeta_system_a' OKAY [ 0.064s]
archive does not contain 'vendor_boot.img'
extracting super_empty.img (0 MB) to disk... took 0.001s
Rebooting into fastboot OKAY [ 0.064s]
< waiting for any device >

等待很长时间也没有响应

3， 仅仅替换dtbo.img, 修改如掉dp connector 修改
烧录不进去，屏幕有显示crash ,见拍照

4，kernel 不做任何修改， android 原生， kernel 不copy
系统能起来，touch可以使用

5，android 原生提换dtbo.img ,重新build boot.img , 仅仅烧写boot.img dbto.img vbmeta.img
adb root adb disable-verity
系统结果：系统不能启动crash

6，android 原生提换dtbo.img sm8150.dtb, sm8150-v2.dtb,重新build boot.img , 仅仅烧写boot.img dbto.img vbmeta.img
adb root adb disable-verity
系统结果：系统不能启动crash
