用于LPC2000系列芯片的程序烧录 /*Hints on Using the LPC2000 Flash Utility This document can be considered as a supplement to the already existing Application note AN10302 “Using the Philips LPC2000 Flash Utility”, which is provided in the same zip file. The Application note covers the following topics: 1. LPC2000 ISP Overview 2. ISP Mode Entry- Manual and RTS/DTR control circuit 3. Flash and RAM buffer operations 4. Keil MCB2100 board and IAR/Philips 210x KickStart board. Topics discussed in this guide are as follows: 1. Using the “Compare Flash” ISP command. 2. Flashless devices- LPC2220, LPC2210, LPC2290 Using the Compare Flash: The below steps need not be carried out if the checksum is part of the code before it is compiled. This would mean that checksum would be part of the hex file been created. For more detailed information on the checksum calculation please refer to the “Flash Memory System and Programming” chapter in the respective device User Manual. In this case, the hex file can be directly loaded using the “Upload to Flash” button and then the “ Compare Flash” button can be used to compare the Flash contents with the hex file. This direct operation is possible since the signature (or checksum) is part of the hex file already. The below steps need to be carried out if the checksum calculation is not part of the code been compiled. In this case, the checksum calculation has to be done by the utility. Step1: Open the “Buffer” menu and browse to “Flash Buffer operations”. When this menu item is clicked the following window will pop-up. Step2: Now click on the “Load Hex file” button. Please browse to the hex file, which needs to be downloaded into Flash. In this case, Blinky.hex would be loaded. Step3: Select the hex file and press “Open”. This would load the hex file into the buffer window as shown below. Please take a note of location 0x14. In this case, the checksum is not computed before the code is compiled. Step4: Now click on the “Vector Calc” button, which would calculate the checksum and load it at the reserved memory location, 0x14. As shown below this location gets updated. The updated value at 0x14 is as shown below Step5: Since this hex file is modified with the checksum, it needs to be saved back into the same location from where it was loaded. Clicking on the “Save Hex File” button would complete this step. When this is done, a message as shown below should appear. Click “Yes”. Step6: Download the hex file into Flash by clicking on the “Download Flash” button. The progress window should show the progress of the Flash download. Step7: The Flash Buffer Operations window can now be closed. Now, please click here and browse to “Blinky.hex” again. Now click the “Compare Flash” button and it should be a success. Flashless devices- LPC2220, LP2210, LPC2290: Since the LPC2220/2210/2290 does not have on-chip Flash, the ISP utility does not have these devices in its listing of supported Flash devices. However, the utility can still be used to issue ISP commands that would access the on-chip SRAM (using RAM Buffer Operations Window) and bootloader specific ISP commands like Read Device ID. For instance, when the above button is clicked, the ISP utility would complain saying that the “Type is not supported” which basically means that this device is not present in the listing of Flash devices. This error message can be ignored. After “OK” is pressed in the above message, the ISP commands will still be executed and the Part ID and the Boot loader ID will be displayed.*/ /*AN10302 Using the Philips LPC2000 Flash utility with the Keil MCB2100 and IAR LPC210x Kickstart evaluation boards Rev. 03 — 10 June 2004 Application note Document information Info Content Keywords LPC2000, Flash utility, Keil MCB2100, IAR LPC210x Abstract Application information for the Philips LPC2000 Flash utility with the Keil MCB2100 and IAR LPC210x Kickstart evaluation boards 9397 750 13354 © Koninklijke Philips Electronics N.V. 2004.

All rights reserved. Application note Rev. 03 — 10 June 2004 3 of 14 Philips Semiconductors AN10302 Using the Philips LPC2000 Flash utility 1. Introduction In-System programming (ISP) is a method of programming and erasing the on-chip flash or RAM memory using the boot loader software and a serial port. The part may reside in the end-user system. The flash boot loader provides an In-System Programming interface for programming the on-chip flash or RAM memory. This boot loader is located in the upper 8 kB of flash memory, it can be read but not written to or erased. 2. LPC2000 ISP overview The flash boot loader code is executed every time the part is powered on or reset. The loader can execute the ISP command handler or pass execution to the user application code. A LOW level, after reset, at the P0.14 pin is considered as the external hardware request to start the ISP command handler. The boot loader samples this pin during reset. Assuming that proper signal is present on X1 pin when the rising edge on RST pin is generated, it may take up to 3 ms before P0.14 is sampled and the decision on whether to continue with user code or ISP handler is made. If P0.14 is sampled LOW and the watchdog overflow flag is set, the external hardware request to start the ISP command handler is ignored. If there is no request for the ISP command handler execution (P0.14 is sampled HIGH after reset), a search is made for a valid user program. If a valid user program is found then the execution control is transferred to it. If a valid user program is not found, the auto-baud routine is invoked. Pin P0.14 is used as hardware request for ISP requires special attention. Since P0.14 is in high impedance mode after reset, it is important that the user provides external hardware (a pull-up resistor or other device) to put the pin in a defined state. Otherwise unintended entry into ISP mode may occur. Figure 1 shows the boot sequence of the LPC210x devices. 9397 750 13354 © Koninklijke Philips Electronics N.V. 2004. All rights reserved.

Application note Rev. 03 — 10 June 2004 5 of 14 Philips Semiconductors AN10302 Using the Philips LPC2000 Flash utility 3. Details of the Philips LPC2000 Flash utility This flash utility is available for free download from the Philips website. This software, in combination with the hardware described below, allows for hands-off erasure, uploading, and execution of code. The Philips LPC2000 Flash utility utilizes two, otherwise unused, signals (RTS and DTR) of the PC serial port to control the microcontroller reset and P0.14 pins. The port pin P0.14, if LOW during reset, puts the microcontroller into In System Programming (ISP) mode; this pin has the alternate functions of external interrupt one and general purpose I/O (GPIO). Some details on the associated circuitry will help in understanding how this works. 3.1 Manual entry into ISP mode With jumper J1 removed and jumper J2 in place ISP mode will be entered manually by holding S2 while pressing and releasing S1 (reset). This can become cumbersome and so it is advantageous to use RTS/DTR control of these signals. 3.2 ISP mode entry using DTR/RTS With jumper J1 inserted and jumper J2 removed the reset and P0.14 signals may be controlled by the previously un-used RTS/DTR signals of the PC serial port. In this application both these signals are active HIGH. When RTS is asserted Q2 is turned on and the microcontroller reset is pulled LOW. While the micro is held in reset, DTR is asserted and P0.14 is held LOW. RTS is then brought LOW and so Q2 is turned off. The 10K pull-up resistor releases the RESET signal by pulling it HIGH. The microcontroller is now running in ISP mode. This sequence of ISP mode entry is performed for every operation offered by the Philips LPC2000 Flash Utility. Fig 2.

Application note Rev. 03 — 10 June 2004 6 of 14 Philips Semiconductors AN10302 Using the Philips LPC2000 Flash utility The main screen of the Flash Utility provides access to most if its functionality. When the “use DTR/RTS…” box (1) is checked then control of reset and P0.14 is done by the utility as described above. If this box is unchecked then ISP mode must be entered manually. If the “execute code after upload” is checked then, after code is programmed into the flash, an extra reset pulse is sent to the microcontroller to reset the part. Since, at this time, P0.14 will be HIGH, the part will execute code in flash after this reset. When the utility connects to the MCB2100 it will attempt to connect at the selected baud rate. The highest baud rate achievable will depend mostly on the frequency of the crystal. Using standard baud rate crystals (e.g. 14.7456 MHz) will increase the maximum baud rate achievable. 3.3 Flash buffer operations The flash buffer operation screen (accessible from the “buffer” pull-down menu) allows functions such as loading a HEX file, downloading from flash, uploading to flash, filling the buffer, saving the HEX file and calculation of the checksum “valid code” vector1. There is also the ability to fill the buffer with a particular value1 and program this buffer to flash. Fig 3. Flash Utility main screen. 1. The valid code vector at 0x14 is merely the two’s complement of the sum of the vector table. By assigning it this value the checksum for the entire vector table is 0x00 which indicates valid flash code. After reset the bootloader will examine this location and, if the value is correct (an indication of valid user code in flash), will execute code out of flash. If the value is not correct the bootloader will enter ISP mode. The Philips LPC2000 Flash Utility will automatically calculate and program this value during an upload to flash. Alternatively the vector calculation may be performed on the contents of flash buffer as shown in the screen-shot below. 9397 750 13354 © Koninklijke Philips Electronics N.V. 2004.

4、HDFS-java操作类HDFSUtil及junit测试（HDFS的常见操作以及HA环境的配置） 网址：https://blog.csdn.net/chenwewi520feng/article/details/130334620 本文编写了java对HDFS的常见操作，并且均测试通过。 其功能包含构造conf、设置系统环境变量、创建目录、判断文件是否存在、获取文件/目录的大小等 在本文中，我们将深入探讨如何使用Java操作HDFS（Hadoop分布式文件系统），以及如何配置高可用性（HA）环境。我们将关注以下几个方面： 1. **HDFSUtil类的构建**： HDFSUtil类是Java中用于与HDFS进行交互的工具类，它封装了HDFS API的基本操作。这些操作包括但不限于： - 构造`Configuration`对象：这是HDFS客户端与HDFS集群通信的关键，用于存储HDFS的相关配置信息。 - 设置系统环境变量：例如，设置HADOOP_CONF_DIR指向HDFS配置文件的位置，以便正确地加载集群配置。 - 创建目录：使用`FileSystem`的`mkdirs()`方法创建HDFS上的目录结构。 - 文件存在性检查：通过`exists()`方法来判断HDFS上某个文件或目录是否存在。 - 获取文件/目录大小：使用`getFileStatus()`获取文件或目录的`FileStatus`对象，从中可以获取文件大小。 2. **JUnit测试**： 使用JUnit测试框架对HDFSUtil类进行单元测试，确保每一种操作都能正常工作。`assertArrayEquals()`, `assertEquals()`, 和 `assertTrue()` 是JUnit中常用的断言方法，分别用于比较数组、值和布尔表达式是否符合预期。 3. **POM.xml配置**： Maven项目对象模型（POM）文件定义了项目的构建、依赖管理等信息。在本例中，POM.xml包含了对Apache Hadoop相关模块（如hadoop-common, hadoop-client, hadoop-hdfs）和JUnit的依赖，确保项目可以正确编译和运行测试。同时，还引入了Lombok库，它提供了一些方便的注解，简化了Java对象的创建和维护。 4. **高可用性（HA）环境配置**： 在高可用性环境中，HDFS通常会配置两个NameNode，以实现主备切换。为了在Java代码中处理这种HA环境，可能需要： - 配置多个NameNode地址：在`Configuration`中设置`fs.defaultFS`为HDFS的HA地址，通常是一个带有`hdfs://`前缀的URL，包含两个NameNode的地址。 - 处理失败切换：使用`FileSystem`的`get()`方法获取`FileSystem`实例时，Hadoop客户端会自动处理NameNode之间的切换，如果当前连接的NameNode不可用，它会尝试连接到备用NameNode。 5. **具体实现**： 文中未展示具体的Java代码实现，但通常，一个简单的HDFSUtil类可能会有如下的方法签名： - `createConfiguration()`: 创建并返回一个配置对象。 - `mkdir(String path)`: 创建指定的HDFS路径。 - `exists(String path)`: 检查HDFS路径是否存在。 - `size(String path)`: 返回HDFS路径的大小。 - `writeToFile(String src, String dst)`: 将本地文件写入HDFS。 - `readFromFile(String src)`: 从HDFS读取文件内容。 以上就是关于HDFSJava操作类HDFSUtil以及JUnit测试的主要内容，它涵盖了HDFS的基础操作和高可用环境的配置，对于在Java应用中集成HDFS操作非常实用。在实际项目中，还需要根据具体需求进行调整和扩展，例如添加数据上传、下载、复制、移动等更多功能。
