    Notes: all our mini2440 boards have the same MAC address, which can be set via software. For Linux users, please refer to section 3.1.1 of this user’s manual. For WinCE users, please refer to the BSP’s DM9000 driver and registry file (platform.reg).

  • Page 241: Audio Interface

    The S3C2440 has an I2S bus interface, it can be connected to an external 8/16 bit stereo CODEC. The mini2440 uses the I2S based UDA1341 chip to implement audio decode/encode system. This chip’s registers’ setting and initialization are controlled by the L3-bus. Here we adopted SAMSUNG’s design by using CPU’s GPB2, GPB3 and GPB4 to simulate the L3-Bus’s standard...

  • Page 242: Jtag Interface

    20Pin or 10Pin. As long as a JTAG interface has those signal lines, it will be a standard JTAG interface. The mini2440 has a 10Pin JTAG interface which has complete standard JTAG signals.

  • Page 243: Gpio

    High Performance Low Cost Embedded Systems GPIO GPIO is the abbreviated form of General Purpose Input Output. The mini2440 has a 34 Pin 2.0mm GPIO interface, i.e. CON4. In fact, CON4 has not only quite a few GPIO pins but also some CPU pins such as AD0-AIN3, CLKOUT and so on.
