@awwwwa 使用cat shadow查看密码
root:$1$vG3nUl9z$3dfKx.qvxATtNKJsHP8pi.:19948:0:99999:7:::
daemon:*:0:0:99999:7:::
ftp:*:0:0:99999:7:::
network:*:0:0:99999:7:::
nobody:*:0:0:99999:7:::
dnsmasq:x:0:0:99999:7:::
sshd:x:0:0:99999:7:::
但是shadow中有密码,是不是说明本来是有密码的?并且我用passwd修改密码,之后查看cat shadow 还是一样的。是为啥?
根据下文
小麻雀直接驱动树莓派的DSI屏
并且按照上文博主提供的对SDK 2.0设备树进行修改
修改设备树后,也按照下文进行的内核的配置
https://d1.docs.aw-ol.com/strong/strong_1display/
但烧录镜像后一直是花屏效果
有大佬可以看看是为什么吗?
ubuntu使用scp传文件给Tina 2.0 SDK ,但是报错密码有误?那它开始的密码是啥?
然后就是用password root修改了密码,但还是一样报错?
有大佬可以解惑一下吗?
只需要修改设备树就行吗,驱动都不用更改?

修改完成后,屏幕还是不亮
