2.2.2 Network Interface
OK6410 The Development Board integrates a 100M Ethernet interface, via Dm9000ae chip to expand. In developing
process, the Ethernet interface can be used to connect PC Machine Download WINCE Mirror, in Linux system development, you can
used to Mount NFS Network File System. When using, connect the PC directly via a crossover cable , or you can use a direct-connect
The network cable connects the switch or router.
Dm9000ae Interrupt Signal Usage s3c6410 Processor Interrupt ' EINT7 ' signal.
The network port socket adopts RJ45 socket, built-in transformer.
2.2.3 JTAG Interface
OK6410 Development Board JTAG interface uses 10X2 pin connector (CN2) .
s3c6410 Processor Design JTAG interface is used to access ARM11 cores or on-chip devices that can be Sbgsel
The configuration of the signal is selected, the specific configuration is as follows:
Dbgsel When the signal is high, JTAG The interface connects the processor peripherals.
Dbgsel When the signal is low, JTAG Connection Access ARM11 Kernel for code debugging.
OK6410 of the Development Board Dbgsel The signal can be passed J9 jumper to select.

2.2.5 User keys
The board has a total of 6 user test keys, which are directly derived from the CPU interrupt pin, belong to the low-power
The 6 keys are defined as follows:
2.2.6 PWM Control Buzzer
Figure 2-11
PWM Control Buzzer
The buzzer buzzer of the Development Board is controlled by PWM0, and the schematic diagram is shown below, wherein PWM0
Should be GPF15, the pin can be set to the PWM output by the software, or it can be used as a normal GPIO.
2.2.7 Startup mode
The S3C6410 processor supports a variety of start-up modes, such as NAND Flash, NOR Flash, and SD cards, to determine the appropriate starting mode by configuring the PIN's different states when the system is powered up.
The OK6410 Development Board selects the boot mode by configuring the DIP switch SW2, as shown in:
Note: (1) The SW2 switch on is "1", when OFF is "0", "X" is high or low level.
(2) OK6410 Development Board Factory default setting is NAND FLASH boot mode.
