关于rock pi 4b+插上电脑后完全无法识别，甚至ADB模式都没有

风火轮用户pt306

之前我在emmc上刷了个debian9镜像，没有问题，
因为需求改变，就在emmc上装了个ubuntu18.04，
然后搞了一段时间后，因为opengl有问题，我拿了一张存储卡作为启动盘，装的也是18.04，然后就一直以存储卡使用rock pi 4b+，
严验证了opengl没有问题之后，我想把存储卡系统转移到emmc上，
但是问题就来了，
系统备份好了之后，
我按照官方教程操作，balenaEtcher、RKDevTool两个下载工具都无法检测到连接，驱动也重新装卸过，设备管理器里面一点反应都没有。
尝试进入MASKROM模式，
通过串口开发板显示的以下信息：

重复多个下面这内容


Could not initialize PHY ethernet@fe300000

Retrieving file: pxelinux.cfg/01-5a-2a-88-86-2d-81

结束是下面：
android_bootloader_boot_flow Could not find misc partition
Android boot failed, error -19.

do_boot_rockchip Could not find misc partition
get part misc fail -1
boot mode: None

上面所涉及的几乎所有关键字我都在网上查了，
也没有找到解决方法，所以请教一下大佬们，
这个该怎么处理啊，除了用SD卡写系统以外？

烧录模式的开关换个方向

多谢大佬指点迷津，烧录模式的开关是指？只看到一个切换按钮，不按的话就是直接启动。。。

刚才我通过短接spi flash的clk之后可以识别为MASKROM模式，并且下载也可以的。
我下载的是官方的最新的：
rockpi-4b-ubuntu-focal-server-arm64-20220801-0355-gpt.img
和rockpi-4b-debian-buster-xfce4-arm64-20220801-0347-gpt.img
这两个都会显示这个同样错误，loader也是最新的rk3399_loader_v1.20.119。

下载rockpi4b-ubuntu-bionic-minimal-20191127_1942-gpt.img就可以正常启动。
