CS-E9302 power supply should be 5V regulated, please do not use otherthan 5V power supply as the power line goes to the USB hosts and if you
apply power supply above 5V this will destroy your USB devices. The
PWR_JACK inner pin is positive.
The board power consumption is about 400-450 mA with 200 MHz CPU
clock and 100MHz system bus.

RESET CIRCUIT:
The EP9302 chip can be reset through the PRSTN pin(power on reset) or
through the open drain common reset pin(user reset) - RSTON pin.
PRSTN is a Power-on Reset realized with MCP130T Reset circuit with typical
2.9V threshold. On the board is present a PRN button which is used for
manual Power-on Reset.
The user reset – RSTON is common for the CS9203 microcontroller, PHY
chip, NOR flash, JTAG and MCP130 Supervisory circuit.
It can be
generated from JTAG pin(15), RSTN button, CS9302 or MCP130T Resetcircuit.

CLOCK CIRCUIT:
EP9302 generates its internal clock with PLL and uses single14.7456 MHz
crystal connected to EP9302 pin 119 (XTAL0) and pin 118 (XTAL1).
The Real Time Clock operates from a 32.768 KHz crystal.

JUMPER DESCRIPTION:
Boot configuration jumpers:
The Hardware Configuration controls are defined by a set of device pins thatare latched into configuration control bits on the assertion of chip reset on
the rising edge of the PRSTN or RSTON pin. The different hardware
configuration bits define watchdog behavior, boot mode (internal orexternal), boot synchronicity, and external boot width. The latched pins are:

EECLK

– Select internal or external bootThe corresponding jumper is EECLK_L. When thejumper is closed EECLK pin is log. “0”, otherwise – log.”1”.

EEDAT– Should be pulled up to “1”The corresponding jumper is EEDAT_L. When thejumper is closed EEDAT pin is log. “0”, otherwise – log.”1”.

TEST[1:0]– Select boot mode
The corresponding jumpers are T0_H/T0_L and T1_H/T1_L
When the T0_H/T0_L jumper is closed to T0_H side TEST0
pin is “1”. When the T0_H/T0_L jumper is closed to T0_L
side TEST0 pin is “0”.
When the T1_H/T1_L jumper is closed to T1_H side TEST1
pin is “1”. When the T1_H/T1_L jumper is closed to T1_L
side TEST1 pin is “0”.

ASDO

– Select synchronous or asynchronous bootThe corresponding 3 pin jumper is ASDO_H/ASDO_L. If thejumper is closed to ASDO_H side – ASDO pin is log. “1”.
The Other side is log. “0”.

CSN[7:6]– Select external boot width.
CSN6 and CSN7 are the jumpers which define logical levelof these pins. If the jumpers are closed – the corresponding
pin is “0”.

On this connector are available all GPIOs of EP9302 which are not used for otherpurposes. With them you can make add-on modules to control with CS-E9302 like
GSM/GPS, input/output add-on boards.

JTAG:The JTAG connector allows the software debugger to talk via a JTAG (Joint Test
Action Group) port directly to the core. Instructions may be inserted and executed by thecore thus allowing MCU memory to be programmed with code and executed step by step by
the host software.

SOFTWARE:
CS-E9302 is distributed with CD with Linux 2.4, NetBSD and Linux 2.6
sources and pre-build images for Linux 2.4, Linux 2.6 and NetBSD.
The boards are pre-loaded with Linux 2.6 in the internal flash.
The software for CS-E9302 could be developed and debugged on desktop
computer then cross-compiled and loaded in the board. Here below is example how to crosscompile “Hello world” program. In most of the cases you do not need JTAG as on the otherembedded systems which do not have RTOS (how often do you develop on your Pentium
desktop computer with JTAG?), but for case where peoples want to blink LEDs without
RTOS we have provided the JTAG connector as well.

Cross-compiling a simple "hello world" example:
Extract one of the provided cross-compilers on your host system and add it to the
PATH variable. Use the cross-compiler to build the example, then transfer it to theboard by e.g. USB flash drive, http download etc.
Example commands:----- On the host system ----# cd /usr/local/arm# tar xjf arm-linux-gcc-4.1.1-920t.tar.bz2...
$ PATH=$PATH:/usr/local/arm/4.1.1-920t/bin$ cat > hello.c#include <stdio.h>
int main(void){
unsigned int i;
printf("\r\nProba proba ");for (i=0; i<10; i++)printf("\r\n%d", i);return 0;}^D$ arm-linux-gcc -o hello hello.c$ cp hello ~/htdocs/----- On the board ----~ # wget http://192.168.0.xx/hello~ # chmod 777 hello~ # ./hello
