MMC process immediately closing, can't link to windows forms

阅读更多关于 MMC process immediately closing, can't link to windows forms

问题 The end goal of what I am trying to do is get the MMC (Microsoft Management Console) Computer Management snap-in (compmgmt.msc) process to be embedded into a Windows Form, or a workaround that will treat it like a modal pop-up menu. Right now, I am just trying to get mmc.exe itself working, before I try to load a snap-in. The first part of the problem is the mmc.exe process almost exits immediately . Edit: mmc.exe only exits immediately if the application is built as 32-bit (my machine is 64

问题 Most (all?) the sample code on the IdentityServer4 docs site uses AddDeveloperSigningCredential() , but recommends using AddSigningCredential() instead in production. I spent more hours than I care to think about trying to figure out how to do that. How do I create a signing certificate and use it in IdentityServer4 in production? 回答1: Create certificate and add to machine's certificate store I decided to create a certificate and add it to the machine's certificate store.

MMC设备 mmc list，可以看出当前板子有两个MMC设备，SD卡和EMMC EMMC分区内容以EMMC为例，看下各个分区中的内容，SD卡类似。分区0 第0个分区存放u-boot。注意前两个块（0,1）存放着分区表，块2存放u-boot，因此更新u-boot一定要从第2个块开始烧写。分区1 分区1存放Linux镜像和设备数文件，为fat格式分区2 分区2存放Linux根文件系统，为ext4格式来源： CSDN 作者： qq_16106195 链接： https://blog.csdn.net/qq_16106195/article/details/104735502

LINUX MMC子系统分析之一概述

阅读更多关于 LINUX MMC子系统分析之一概述

从本章开始，我们分析mmc子系统，其也遵循LINUX设备-总线-驱动模型，并基于自身的特点进行了相应的抽象。针对本专题，我们主要涉及如下几个章节：一、MMC子系统概述；二、MMC子系统驱动模型分析（包括总线、设备、驱动）；三、MMC总线分析四、MMC host分析五、MMC driver分析六、MMC card添加流程分析七、MMC block分析本篇为此系列的起始，主要对MMC子系统进行一个简要的概述说明。针对MMC来说，主要包括几个部分：MMC控制器、MMC总线、card。针对卡而言，包括MMC卡（7pin，支持MMC和spi两种通信模式）、SD卡（9pin，支持sd和spi两种通信模式）、TF卡（8pin，支持sd和spi两种通信模式），针对MMC、SD而言，其总线规范类似，都是从MMC总线规范演化过来的。另外上面所说的均是针对存储卡而言，而基于MMC这种通信方式，又演化了SDIO，SDIO强调的是IO，与MMC/SD的区别主要是连接的设备，其不再仅仅是存储卡，可以链接任何支持SDIO的外设（包括蓝牙设备、wifi设备等）。其实SDIO的实现则和我们之前分析的IIC、SPI总线类型，通过SDIO可以连接各种类型的设备（wifi、bluetooth、uart、gps、esata等） CPU、MMC之间的硬件关联图 CPU、MMC controller

了解 sdhci host driver. 1.概述 The MultiMediaCard (MMC)/ Secure Digital (SD)/ Secure Digital Input Output (SDIO) host driver implements a standard Linux driver interface to the ultra MMC/SD host controller (microSDHC). The host driver is part of the Linux kernel MMC framework. 1.1.Kernel configuration You can manage the MMC driver support through the kernel configuration options: MMC/SD/SDIO (CONFIG_MMC) MMC block (CONFIG_MMC_BLOCK) Secure Digital Host Controller Interface support (CONFIG_MMC_SDHCI) SDHCI support on the platform-specific bus (CONFIG_MMC_SDHCI_PLTFM) 2.数据结构 2.1.struct sdhci_host

一、uboot启动分为了三个阶段BL0、BL1、BL2； BL0 表示上电后运行ROM中固化的一段程序，其中ROM中的程序是厂家写进去的，所以具体功能可能根据厂家芯片而有所不同。功能如下：初始化系统时钟、特殊设备的控制器、启动设备、看门狗、堆栈、SRAM等硬件；验证B1镜像，并且加载BL1镜像到SRAM中，然后跳转到BL1镜像的地址上。 BL0需要将BL1加载到对应的RAM上，这就涉及到它的启动模式，详细如下： 1.OneNand Boot模式要了解OneNAND先得了解NOR Flash和NAND Flash。与NOR Flash相比，NAND Flash的读数据速度稍慢，但是擦写速度快得多，并且在容量、使用寿命、成本上也占有较大优势。NOR Flash的编程简单，而NAND Flash的编程较为复杂（因为它的flash管理需要特殊的接口）。NAND Flash一般用于存储数据，而NOR Flash一般用于存储启动代码。 NOR Flash带有SRAM接口，有足够的地址引脚来寻址，可以很容易地存取其内容的每一字节（有限的地址引脚是限制其容量的因素之一）。NAND Flash使用复杂的I/O口来串行地存取数据，各个产品或厂商的方法可能各不相同。为了弥补NAND Flash的不足，三星公司在NAND Flash芯片内集成了一个RAM接口，命名为OneNAND Flash
