WEC7启动时间 [英] WEC7 Boot Up Time

问题描述

您好，

我有一个x86平台（baytrail），我正在使用biosloader来启动我的图像。我的图像无头，大小不到4 MB。我试图让平台尽快启动。使用内核跟踪器我看到我的图像需要大约
3秒才能加载所有驱动程序并开始执行我的应用程序。然而，生物加载器本身需要大约7秒才能达到驱动程序开始加载的程度（让我的启动时间大约为10秒）。如何加速启动过程的biosloader部分
，还是使用比bootloader更快的另一个bootloader？无论我是从SSD还是USB或拇指驱动器启动，我都有相同的启动时间。我没有硬件调试器来检查在电路板上施加
电源和驱动器开始加载之间发生了什么。有没有人有使x86 biosloader（或其他引导装载程序）启动速度超过7秒的经验？

I have an x86 platform (baytrail) that I am using biosloader to boot my image from. My image runs headless, and is less than 4 MB in size. I am trying to make the platform boot as quickly as possible. Using kernel tracker I see that my image takes around 3 seconds to load all the drivers and start executing my application. However, biosloader itself takes around 7 seconds to get to the point where drivers start to load (giving me a boot up time of around 10 seconds). How can I speed up the biosloader portion of the boot process, or is there another bootloader that is used that is faster than bootloader? I have the same bootup time whether I'm booting from and SSD or a USB thumb drive. I don't have a hardware debugger to check what is happening between the time power is applied to the board and the drivers start to load. Does anyone have experience with making x86 biosloader (or other boot loader) booting faster than 7 seconds?

谢谢

嗨elk84，

Hi elk84,

Biosloader在源代码@ C：\ WINCE700 \platform\CEPC\src\bootloader\biosloader中可用
确实可以默认5秒延迟选择备用启动文件@ boot.ini -

Biosloader is available in sources @ C:\WINCE700\platform\CEPC\src\bootloader\biosloader
Indeed there can be default 5 seconds delay to choose alternative boot file @ boot.ini -

＃启动延迟（以秒为单位）选择替代图像

延迟= 5

# Boot delay (in seconds) in which to select the alternative image
Delay=5

祝你好运，伊戈尔
