Note: Issue: COM port limitation for the speed test during the communication.

Root Cause:

In serial communication, data bits received at the serial port are bundled into a byte and transmitted into the serial port hardware buffer. From the buffer, the byte is sent into the CPU. If a new byte arrives before the byte in the buffer is moved into the CPU, a Hardware Overrun Error occurs.

Solution:

1. Try hardware handshaking.

2. See if the UART is an older un-buffered version or a new buffered UART (such as a 16550A or 16750). You should use a buf fered UART for the reasons discussed above.

3. Change the Receive (Rx Trigger) buffer to 8, 4, or 1 (1 is a last resort).

4. For the product, the speed setting of Series Port (COM) is under 9600bps.

3.1 System Test and Initialization

These routines test and initialize board hardware. If the routines encounter an error during the tests, you will either hear a few short beeps or see an error message on the screen. There are two kinds of errors: fatal and non-fatal. The system can usually continue the boot up sequence with non-fatal errors. System configuration verification

These routines check the current system configuration against the values stored in the CMOS memory. If they do not match, the program outputs an error message. You will then need to run the BIOS setup program to set the configuration information in memory.

There are three situations in which you will need to change the CMOS settings:

1. You are starting your system for the first time

2. You have changed the hardware attached to your system

3. The CMOS memory has lost power and the configuration information has been erased.

The TKS-G21-CV05 CMOS memory has an integ ral lithium battery backup for data retention. However, you will need to replace the complete unit when it runs down.

3.2 AMI BIOS Setup

AMI BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed CMOS RAM so that it retains the Setup information when the power is turned off. Entering Setup Power on the computer and press <Del> or <F2> immediately. This will allow you to enter Setup.

Note:

1. If the "Control LVDS2 (CH7511)" has been set "Disable," and then, the

screen cannot be switched to LVDS2 under the OS.

2. If the "Control LVDS2 (CH7511)" has been set "Enable," and then, the

screen can be switched to LVDS2 under the OS.

3. This model does not support LVDS2 output under DOS mode. So if it is a

dual LVDS application, users have to enable “Onboard LVDS 2” on the LVDS1 panel under BIOS interface, and then, enter to the OS.

4. For LVDS1 + LVDS2 application, this model does not support scaling

after entering the OS, users have to set the fixed resolution on their LCD Panel under BIOS interface, and then, enter to the OS.

Appendix A Programming the Watchdog Timer A-1

Embedded Box TKS-G21-CV05

A.1 Programming

TKS-G21-CV05 utilizes ITE 8783 chipset as its watchdog timer controller. Below are the procedures to complete its configuration and the AAEON initial watchdog timer program is also attached based on which you can develop customized program to fit your application.

Configuring Sequence Description

After the hardware reset or power-on reset, the ITE 8783 enters the normal mode with all logical devices disabled except

KBC. The initial state (enable bit ) of this logical device (KBC) is determined by the state of pin 121 (DTR1#) at the falling edge of the system reset during power-on reset.

Appendix A Programming the Watchdog Timer A-2

Embedded Box TKS-G21-CV05

There are three steps to complete the configuration setup: (1) Enter the MB PnP Mode; (2) Modify the data of configuration re gisters; (3) Exit the MB PnP Mode. Undesired result may occur if the MB PnP Mode is not exited normally.

(1) Enter the MB PnP Mode

To enter the MB PnP Mode, four special I/O write operations are to be performed during Wait for Key st ate. To ensure the initial state of the key-check logic, it is necessary to p erform four write opera-tio ns to the Special Address port (2EH). Two dif f erent enter keys are provided to select configuration ports (2Eh/2Fh) of the next step.

(2) Modify the Data of the Regist ers

All configuration registers can be accessed after entering the MB PnP Mode. Before accessing a selected register, the content of Index 07h must be changed to the LDN to which the register belongs, except some Global registers.

(3) Exit the MB PnP Mode

Set bit 1 of the configure control register (Index=02h) to 1 to exit the MB PnP Mode.

WatchDog Ti mer Configuration Registers

Configure Control (Index=02h)

This register is write only. Its values are not sticky; that is to say, a hardware reset will automatically clear the bits, and does not require the software to clear them.

C.1 Digital I/O

The F75111 provides one serial access i nterface, I2C Bus, to read/write internal registers. The address of Serial Bus is 0x6E (0110_1110)

The related register for configuring DIO is list as follows:

Set this bit to 1 will enable auto power down mode, when all function are idle then 20ms the chip will auto power down, it will wakeup when GPIO state change or read write register Set this bit to 1 will power down all of the analog block and stop internal clock, write 0 to clear this bit or when GPIO state change will auto clear this bit to 0.
