您好，我必须如何配置和谐配置器来在HTTP网络服务器的外部闪存（SST25）中存储网页？我用PIC32 MZ谢谢
以上来自于百度翻译 以下为原文 Hello, How must I configure HARMony configurator to store web pages in an external flash (SST25) for HTTP NET Server ? I use PIC32MZ Thanks

在你走得更远之前，肯定会指出SST25芯片被弃用，不推荐用于新的设计。您会发现，SST26芯片更容易使用，而且更快，因为它们使用页面写入，而不是自动增量地址（Word）编写。此外，这是SPI还是SQI？记住，在PIC32 MZ中有一个闪光灯的量规。为什么不使用内部闪存作为存储介质呢？
以上来自于百度翻译 以下为原文 Before you go too much further, it will most assuredly be pointed out that SST25 chips are deprecated and not recommended for new designs. You'll find that the SST26 chips are MUCH easier to work with, and faster, since they use page writing as opposed to the auto-increment address (word) writing. Also, is this SPI or SQI? Bear in mind that you have a metric crapton of flash in a PIC32MZ. Why not just use internal flash as your storage medium? |

我想使用SST26而不是SPI模式。SST25是由SPI驱动程序管理的，但不是SST26的：这不是问题，因为它很容易适应SPI驱动程序源代码来管理SST26（我之前购买SST25测试源代码来尝试实现SST26）。2，不可能使用SPI和以太网外设（SPI外围使用相同的PIN以太网外围）。我想使用外部闪存，因为我需要所有内存的内部闪存来存储我的程序。我在哪里可以找到一个使用和声与SST25的例子？我必须使用的卷名是什么？
以上来自于百度翻译 以下为原文 I want use SST26 but in SPI mode (not SQI). SST25 is managed by SPI driver but but not for SST26 : It isn't a problem because it is easy to adapt SPI driver source code to manage SST26 (I bought SST25 to test source code before to try to implement SST26). I can't use SQI mode because with 64-pin PIC32, it is impossible to use SPI and Ethernet peripherials (SPI peripherial use same pins that Ethernet peripherial). I want to use external flash because I need all memory of internal flash to store my program. Where can I find a exemple to use Harmony with SST25 ? What is volume name that I must use ? |

现在，尝试使用内部闪存来启动和运行Web服务器。这是真的，经过测试。因此，在这些论坛上的人们将能够帮助你获得和运行。最好是系统化的：如果你知道你的Web服务器在内部运行，那么任何试图将它从Flash中运行出来的东西都可能是因为你的SST25、SPI或文件系统服务设置。在你的SST25驱动程序下，你需要将它注册到文件系统中；有一个选项A。可以在2.05完成这个任务。文件系统需要为MPFS安装，MPFS是Microchip用于这些网页的文件系统。您还需要在代码中的某个地方安装一个调用，以确保文件系统被正确安装。这将给代码添加一些阻塞，尽管我不确定有多少。MPFS驱动程序与SST25驱动程序的任务函数处于一个循环中。您可能需要让您的SPI任务驱动程序在中断模式下运行。
以上来自于百度翻译 以下为原文 For now, try and get the web server up and running with internal flash. It's tried, true, and tested. Therefore, the people on these fora will be able to help you get that up and running. It's best to be systematic: if you know that your web server runs internally then anything that screws up attempting to run it out of flash is probably due to your SST25, SPI, or file system service setup. Under your SST25 driver, you'll need to register it with the file system; there is an option available to do this in 2.05. The file system will need to be setup for MPFS, which is the filesystem that Microchip uses for these webpages. You will also need to include a call to mount somewhere in your code to ensure that the file system is mounted properly. This is going to add some blocking to your code, though I'm not sure how much. The MPFS driver sits in a loop with the tasks function for the SST25 driver. You may need to make your SPI tasks driver run in interrupt mode for this to work. |

我的代码是用内部闪存操作的，而不是外部闪存。在App.c中，我做的是：在SPI驱动程序中传递Flash ID检查。当我尝试打开网页时，HTTP连接被重新设置DHCP并发现操作。
以上来自于百度翻译 以下为原文 My code operate with internal flash but not with external flash. In app.c, I do : #define SYS_FS_DRIVE "SST25" #define SYS_FS_SST25_VOL "/dev/mtda1" case APP_MOUNT_DISK: if(SYS_FS_Mount(SYS_FS_SST25_VOL, LOCAL_WEBSITE_PATH_FS, MPFS2, 0, NULL) == 0) { SYS_CONSOLE_PRINT("SYS_Initialize: The %s File System is mountedrn", SYS_FS_MPFS_STRING); appData.state = APP_TCPIP_WAIT_INIT; } break; ... Flash ID check is passed in SPI driver. When I try to open a webpage, HTTP connection is reseted DHCP and discover operate. |

你使用DMA吗？如果这样，MPFS可能需要一些修改。

我不在SPI上使用任何东西。我不使用DMA。@弗里森：在MPFS.C上有相同的问题，用于SPI闪存（我在循环中固定，现在，和声初始化操作……现在我必须修改HTTP网络服务器来上传MPFS文件：MPFSUPPLAD页面不运行。只有当我在SPI外设上使用DMA时，SysSeDeViNoDATAcACHeMealIdAID（）才有用吗？
以上来自于百度翻译 以下为原文 I don't use anything else on SPI. I don't use DMA. @friesen : there is same problem on mpfs.c for SPI flash (I fixed while loop and now, Harmony initialization operate... now I must modify HTTP Net server to upload MPFS file : mpfsupload page doesn't operate). SYS_DEVCON_DataCacheInvalidate() is usefull only if I use DMA on SPI peripheral ? |

在SPI模式下管理SST26的最好方法是升级SST25SPI驱动程序或SST26SQI驱动程序？
以上来自于百度翻译 以下为原文 The best way to manage SST26 in SPI mode is to upgrade SST25 SPI driver or SST26 SQI driver ? |

我不确定你在问什么。但是，我会说SST26SQI驱动程序并不是没有什么头痛的。我认为您可以在SPI模式下工作，同时在SQI驱动程序中使用一些模式位，但没有记录。
以上来自于百度翻译 以下为原文 I'm not sure what you are asking. However, I will say that the SST26 SQI driver isn't without some headache. I think you could get it to work in SPI mode with some fiddling with the mode bits in the sqi driver, but its not documented. |

你好，我做了一个调试函数来查看SST25Flash中的数据。这个函数在AppHytasks-（）中被调用：这个代码不运行：PrTrF错误消息总是显示（PrtTf（[Err] Debug）SysSyfsMyaAuxMauleSerixTope%PRn，SysfSimaTyAuthRoad；）当我注释我的代码代码时，我可以显示网页，但是当我启用我的函数时，我不能播放网页。问题是什么？谢谢

我不太确定，但那里确实很重。如果你想让它工作，把你的单词数降到最小和波特率到最大。
以上来自于百度翻译 以下为原文 I'm not sure right off, but that is real heavy right there. If you want it to maybe work, lower your word count to minimum and baud rate to maximum. |

我在DrviSt2525Orth.h中发现了一个错误：在DrviSt2525Obl结构中，CMDPARAMLSEN必须是UTI1616T（不是UTIT8YT）。问题是在页面编程功能中：UIT88T太小，不能存储256×4的64 MB内存值。现在我可以在SST25和SST26上传网页，我可以显示网页。想限制网页的大小来存储自定义数据（配置文件、日志文件、临时固件、……）：是否可以在不更改协调源代码的情况下执行？是否可以在闪光灯上同时使用MPFS2和FAT？
以上来自于百度翻译 以下为原文 I found a bug in drv_sst25_local.h : in DRV_SST25_OBJ structure, cmdParamsLen must be a uint16_t (not a uint8_t). Problem is in page program write function : uint8_t is too small to store the value of 256+4 for 64Mb memories. Now I can upload web pages on SST25 and SST26 and I can display web pages. I would like to limit size of web pages to store custom data (config file, log files, temporary firmware, ...) : is it possible to do it without change source code of Harmony ? => is it possible to use MPFS2 and FAT at the same time on a Flash ? |
