问题描述

编译成功之后，./qemu-run报错如下：

DeviceManagerStart start ...
[ERR][KProcess:SystemInit]virtio-mmio ID=1 device not found
SoftbusLwipMonitorInit init success...
DeviceManagerStart end ...
OsMountRootfs start ...
[ERR][KProcess:SystemInit]Cannot find bootargs!
[ERR][KProcess:SystemInit]parse bootargs error!
[ERR][KProcess:SystemInit]Cannot find root![ERR][KProcess:SystemInit]mount rootfs error!
OsMountRootfs end ...
virtual_serial_init start ...
virtual_serial_init end ...
system_console_init start ...
system_console_init end ...
OsUserInitProcess start ...
OsUserInitProcess end ...
[ERR][Init:thread0][VFS]lookup failed, invalid path err = -22
什么原因？已经生成了smallmmc.img和flash.img文件。

删除out/smallmmc.img重试下，，

终于可以了！还想问一下，liteos-a系统启动过程打印的内容很少，能调整到像linux内核启动那样打印的很详细吗？

发个启动成功的截图？很久未看到了～
详细输出日志得自己hack了

启动如下，有一些报错，但是也进到了命令行。还想问一下，这个demo没有图形化界面生成吗？liteos-a支持屏幕app吗？

多谢！demo曾短暂地有过图形界面，但目前已远滞后于OHOS，liteos-a支持屏幕app。这个demo期待有兴趣者能接续开发维护，，

好的，多谢！
