rockchip soc上安装时遇到的一些问题

aosc arm64安装时的串口波特率比较奇怪 在rk3566测试安装了一下 发现如下逻辑

背景

  1. rk3566 spinor 使用 UEFI 启动 跳转到sd卡启动 uefi传递设备树(不传递ACPI)
  2. 由于瑞芯微祖传的1500000波特率 我也从善如流编译uefi输出1500000波特率

现象

  1. spl到uefi到aosc的bootloader(我猜是这?最后的日志是Checking EFI serial console …) 这一段串口输出波特率都是1500000 输出正常
  2. aosc进入语言选单时,串口开始使用9600波特率 选中语言 选中串口执行安装
  3. 启动内核,内核日志和systemd均以115200波特率输出,跟设备树(存疑,uefi传的设备树就是115200也未可知)和初始的语言选单均不一致

使用3588 UEFI启动测试时 同样可以最后看到Checking EFI serial console 通过HDMI确认可以进入语言选单 但在默认串口上切换了几个 常用波特率并按上下键 均看不到语言选单刷新

3566启动到文件系统后遇到了其他错误,是dracut的init_queue启动失败
具体日志如下
