Interface wiring tool for the Development Board

The arm Development Board is essentially a small computer system. Therefore, you can compare the Learning Development Board with a PC computer.
    A new computer needs to be installed with a system (pre-installed by the manufacturer or installed by yourself) before it can be used. In the same way, the Development Board must first burn the software before it can be used. PC computers can be installed on a CD system and used on keyboards and monitors. For Development Boards, you can use the JTAG interface to write software and use the serial port as the input and output.
    PC computers generally have CPUs, memory, hard disks, NICS, parallel serial ports, and so on. Correspondingly, the Development Board also has CPUs, memory, flash (equivalent to PC hard disks), NICS, and serial ports.

    1. Interface wiring:
    1> parallel port: connect the JTAG interface and the JTAG adapter of the Development Board with a cable. If the PC does not have a parallel port, connect the parallel JTAG adapter to the parallel port of the PC, if the PC does not have a parallel port, you can use USB to switch to the JTAG board for connection. The USB to JTAG board can be openjtag or jlink. Because you do not have JTAG and openjtag, select jlink.
    2> serial port: for the Development Board, a serial port is usually used to connect to the USB serial port card and then to the serial port of the PC. However, the jz2440v2 Development Board will be integrated into the development board, so you can directly use USB cable to connect the Development Board USB-COM1 port and pc usb port.

    2. Install the driver:
    1> If the PC has a parallel port, install the parallel port driver. For details, refer to 2.2.1windows in the 4.3 inch LCD edition user manual for jz2440 Development Board.
    2> jz2440v2 integrated USB serial port: Run pl2303_prolific_driverinstaller_v1.5.0.exe, and then connect USB cable (USB-COM1 port on the Board <===> pc usb port)

    3. Install software:
    1> install the program-Burning Software oflash: Copy oflash.exe and ftd2xx. DLL to c: \ windows \ system32 to run the oflash software on the command line of the PC.
    2> install securecrt and click scrt522.exe under the "WINDOWS \ tools \ scrt522" directory.

    4. Use the serial port to operate the Development Board. Press the Space key within 3 seconds to enter u_boot. Otherwise, the system runs directly. This is the same principle as pressing the delete key in Windows to enter the BIOS.
