Hi, we update rootfs, and then the device cann’t dispaly, the below is the uart log:

What did you change in rootfs?

我们在新制作rootfs时，采用ustc路径， 之前不是，之前应该就是ubuntu-base-18.04.6-base-arm64默认的，其他的不变，我认为这不应该影响gpu部分。
echo “deb Index of /ubuntu-ports/ bionic main” > /tmp/mk-base-ubuntu-sources.list
echo “deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-updates main” >> /tmp/mk-base-ubuntu-sources.list
echo “deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic universe” >> /tmp/mk-base-ubuntu-sources.list
echo “deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-updates universe” >> /tmp/mk-base-ubuntu-sources.list

echo “deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-updates multiverse” >> /tmp/mk-base-ubuntu-sources.list

sudo cp /tmp/mk-base-ubuntu-sources.list $TARGET_ROOTFS_DIR/etc/apt/sources.list

error no “-2” means the “No such file or directory”.

开机的logo画面可以显示，但进入kernel后，就开始出现gpu error, 但这个rootfs在我们把L4T 升级到R32.7.3上不会出错，在r32.5.1上会出这个错误。
之所以会有这个发现是：原本我们升级到R32.7.3时，使用之前的rootfs也是会出这个错误，所以修改了下rootfs后，尽然可以了，比较困惑，现象上看确实跟rootfs有关系

7

Boot logo is from cboot. Nothing to do with rootfs…

8

有命令可以重启下gpu吗，或者这个错误跟时序有没有什么关系

9

我大概知道什么原因了，你们从32.5.1升级到32.7.3时一些在rootfs中的deb包有更新，所以如果我们只升级L4T，不升级rootfs就会有问题
