Description: FLASH 测试
VMD642 开发板上的 flash 芯片为 Spansion 本例程在 VMD642_flash 目录中。
FLASH 的测试主要包括 FLASH 的擦除和读/写操作，以及其在存储空间中的映射是否
正确。
首先配置 EMIF，使得 FLASH的 8 个 512K空间映射到 DM642的存储空间中。
擦除 FLASH 的 8 个页面。
VMD642_rset(VMD642_FLASHPAGE, page) 设置当前页面。
在 VMD642 开发板中 4M 的 flash 空间被分为 8个 512k 页面，每个 512k的页面由 8 个
64k 的 sector组成。但注意在 Spansion 的这个 FLASH芯片中，
它的4M的地址空间是这么安排的： 总共72个sectors, 其中sector 0-7 为 8k， .sector 8-63
为 64k。
所以，在 VMD642-C 中的第一个页面的第一个 sector又分为8 个8k的 sub sectors。
擦除完后，向 FLASH中写入以每页的页数开始的顺序数据。
按同样顺序依次读出 FLASH 中的数据，比较读/写是否正确。 -FLASH test VMD642 development board flash chips for Spansion This routine VMD642_flash directory. The tests include FLASH FLASH erase and read/write operations, and the storage space in which the mapping is correct. First configure the EMIF, making the FLASH 8 512K space is mapped to the DM642 memory space. Erase the FLASH 8 pages. VMD642_rset (VMD642_FLASHPAGE, page) setting the current page. In VMD642 development board 4M of flash space is divided into eight 512k pages, each page 512k 64k by the eight components of the sector. But note this in Spansion FLASH chip, it' s 4M address space is so arranged: total 72 sectors, including sector 0-7 of 8k,. Sector 8-63 of 64k. Therefore, in VMD642-C in the first page of the first sector is divided into 8 8k the sub sectors. After erase, write to the FLASH pages per order starting data. By the same order of the data read out FLASH compare read/write is correct.

Description: UART 测试
本例程在 VMD642_uartio 中。
VMD642-C卡中有两路 UART 接口，在本例中，UART 的接口标准配置为
RS232，波特率-9600，数据位-8，校验位-None, 停止位-1，采用查询工作方式。
在目录 Win32\serial 下提供一个串口调试器.exe，注意设置正确的波特率。
用开发板随带的串口线将 DSP 开发板的串口和计算机串口连接好，启动串口调试
器.exe，设置串口参数，然后打开串口，就可以在发送窗口发送字符，同时在接收窗口接收
DSP 端传回的数据-UART test
The routines in VMD642_uartio.
The VMD642-C card has two UART interface, in this case, the standard configuration for interface UART
RS232-9600, baud rate, data bits-8, check-None, stop-1, the query mode.
To provide a serial debugger.Exe in the directory Win32\serial, pay attention to set the correct baud rate.
The serial port and the serial port of the computer DSP development board is connected with the development board with the serial line, start the serial debugging
Device.Exe, set the serial parameters, then open the serial port, can send window to send characters, while receiving window
DSP returns the data

Description: DM642的网络开发。这个是网络传输的例程，基于NDK1.7的client 例子，
可以运行在VMD642开发板上。
1、需要首先安装NDK1.7
2、client.pjt工程文件在evmdm642目录里
3、工程运行后，在stdout窗口中会显示出当前板卡的IP地址。
缺省的采用固定IP地址：192.168.1.107
你可以修改这个地址，如果是DHCP方式，请改为0.0.0.0
4、工程运行后，可以用winapps里的客户端例程来测试，请在dos prompt里运行
比如运行 echoc 192.168.1.107,你就能看到网络收发数据，对应的服务器程序在
client里的echosrv.c
5、支持web浏览,可以在IE里输入板卡的IP地址来访问
-DM642 web development. This is the network transmission routines, based on client examples NDK1.7 of
Can run VMD642 development board.
1, you need to first install NDK1.7
2, client.pjt project file directory in evmdm642
3, after the project is running in the stdout window displays the current IP address of the board.
The default fixed IP address: 192.168.1.107
You can modify this address, if it is DHCP, please read 0.0.0.0
4, after the project is running, you can use winapps in client routines to test, run in dos prompt in
Such as running echoc 192.168.1.107, you will be able to see the network to send and receive data, the corresponding server program
client in the echosrv.c
5, support for web browsing, you can enter the IP address of the card to access in IE
