如何建立稳定的rPi设备？新图像无法启动，7个LED闪烁，BCD错误 [英] How do I establish a stable rPi device? New images wont boot, 7 LED flashes, BCD errors

问题描述

我在一段时间后回到Core IoT - 之前的构建很棒（14393,14x等）。 我现在更新到最新的VS 2017预览版，最新的仪表板，相同的硬件和SD卡，并尝试加载17134和17744但没有运气。

I am getting back to Core IoT after some time away - the prior builds were great (14393, 14x, etc).  I've now updated to the latest VS 2017 Preview, the latest Dashboard, same exact hardware and SD card, and tried loading 17134 and 17744 with no luck.

我得到两个症状之一：

黑色屏幕（无显示），绿色LED闪烁7次

Black screen (no display) with 7 flashes on the green LED

或

引导错误屏幕：  "Windows无法启动"，"文件：\ef1 \ microsoft \ boot \ BCD""，"状态：0xc000014c"，""您的PC的启动配置数据丢失或包含错误。

Boot error screen:  "Windows failed to start", "File: \ef1\microsoft\boot\BCD", "Status: 0xc000014c", "The Boot Configuration Data for your PC is missing or contains errors.

这些问题都出现在这里的一些旧线程中：

建议包括：  

Suggestions include:  

• 您必须使用正确的SD媒体 - 获取支持的SD卡
• 您必须确保您的电源充足
• 您在写入磁盘时因断电而出现错误 - 请勿执行此操作

所以在任何人提出这些明显的建议之前，请考虑以下事项：

So before anyone makes these same obvious suggestions, please consider the following:

• 我有两个覆盆子pi 3 B（不 +型号）以排除硬件问题 
• 我有两张SD卡，官方支持的SD卡与官方硬件兼容列表相关联。 （三星Evo和Sandisk Ultra，从发布的链接中购买）
• 我有两个电源，2.5A，官方流行的CanaKit品牌，在旧版本上与Core IoT配合使用
• 无论上述组合如何，都会出现相同的故障
• 使用以前版本的Core IoT在同一硬件上没有出现此类故障
• 我一如既往地闪存SD，只需使用仪表板（建立17134和17744尝试）

• I have TWO raspberry pi 3 B (not the + model) to rule out hardware issues 
• I have TWO SD cards, BOTH of the officially supported ones linked from the official Hardware compat list. (Samsung Evo and Sandisk Ultra, literally bought from the links posted)
• I have TWO power supplies, 2.5A, official popular CanaKit brand, worked great with Core IoT on older builds
• Same failures no matter what combo of the above
• No such failures on this same exact hardware using prior builds of Core IoT
• I flash the SD's same as always, simply using the Dashboard (builds 17134 and 17744 attempted)

考虑到所有这一切，请告诉我我做错了什么或没做错考虑。

With all of this in mind, please tell me what I have done wrong or failed to consider.

当然，宇宙中有一定几率我有一个坏组件，尽管有两套完整的东西 - 实际上我有更多的SD卡在上路怀疑。 但更有可能的是我在这里所经历的，在以前的
构建中表现不错，17xxx构建的Windows IoT Core不太稳定，对引导问题更敏感，或者超级IO不容忍期待SD完美。 

Sure, there is a % chance in the universe I have a bad component despite two complete sets of everything - and in fact I have more SD cards on the way to address that suspect.  But more likely from what I have experienced here, having been fine on prior builds, 17xxx builds of Windows IoT Core are way less stable, way more sensitive to boot issues, or super IO intolerant expecting SD perfection. 

推荐答案

一旦拿到其他SD卡，我很想听听结果。

I'm curious to hear the results once you get your other SD cards.

我对使用不在官方列表中的卡片有更好的体验。我最终会比现场更频繁地丢失现场图像（损坏？），但通过快速重新映像操作系统和重新部署应用程序，很容易解决这个问题。

I've had better experience with cards that aren't on the official list. I do end up losing images in the field (corruption?) more frequently than I'd like, but that problem is easy to fix with a quick re-image of the OS and re-deployment of the app.

由于稳定性问题，我最终离开了内部版本。在过去的几个月里，主线版本对我来说相当稳定。

I did, eventually, move off of the insider builds due to stability issues. The mainline builds have been fairly stable for me for the last few months.
