Chapter 4. Examples 4.1. Loopback Test
4.1.1. Run Program from Flash ROM
Loopback program is used to test communication capability of i2Chip W3100 on 8051EVB. Communication speed test is performed by sending data from PC to 8051EVB, then having 8051EVB send the received data back to PC.
4.1.1.1. Test Environment The Loopback program has been pre-loaded into Flash ROM as
default application, to facilitate immediate testing of 8051EVB board without additional effort spent for set-up.
First, install Axinstall.EXE (located on CD, in directory Software\PC\Loopback\) on the PC. The set-up program will create a new application, called AX1.EXE, needed to run Loopback test.
To test a new program from Flash ROM, set the CN2 jumper to 2 & 3, and then download the program (start from memory address at 0x0000) using ROM Writer. Connect power, Serial and UTP cables, before powering up. The program can be monitored using HyperTerminal from PC. Use Reset key on 8051EVB board in case of initial difficulty. 4.1.1.2. Loopback Test Procedures ① Set CN2 jumper to 2 & 3
17
② Ping 8051EVB board to confirm proper operation of Network functions.
※ The default IP address on 8051EVB board is 211.171.137.38. User can change this IP address on Flash ROM in 8051EVB by ROM writer.
C:\> ping 211.171.137.38 –t
Picture 4-1. Ping Test Command
③ Run AX1.EXE from PC
Picture 4-2. AX1.EXE Program
④ From ‘TCP’ menu in AX1 program, select ‘Connect’ to get a dialog box shown in Picture 4-3. Enter IP address and Port ID in the dialog box, and press ‘OK’ to connect.
18
Picture 4-3. Connection Information Entry
⑤ When connection has been established, following dialog box is displayed.
Picture 4-4. Connection Established
⑥ Select ‘Send’ from ‘File’ menu to start transferring file for test. ⑦ Select file to start the Loopback test.
Picture 4-5. File Transfer
※ Using ‘A(uto)’ command or ‘I(teration)’ command, the Loopback test can be repeated continuously. The ‘S(end)’
19
command must be performed prior to using ‘A(uto)’ command or ‘I(teration)’ command.
Picture 4-6. Continuous Loopback Test
4.1.2. Run Program from RAM
First, set CN2 jumper to 1 & 2, connect cables, then power up. The application progress can be monitored from PC via HyperTerminal.
From the Monitor program menu, select ‘D’ to download (start from memory address at 0x4000) into RAM. When download has been completed, the completion message will display, and it will return to the Monitor program menu. From the Monitor program
20
menu, select ‘R’ to run downloaded program (refer to 4.2 for procedures to test using the Monitor program).
4.2. Testing with the Monitor program
The Monitor program is included with 8051EVB board to aid development. The Monitor program allows the developer to load their custom program into SRAM to test, and at the same time, monitors memory usage.
The Monitor program communicates with PC through Serial Port connection. A Serial cable (cross cable) is included in the 8051EVB package.
4.2.1. Test Procedures
① Connect 8051EVB to PC using a Serial cable. Open HyperTerminal provided by Windows OS (other similar programs, i.e. Serome’s DataMan, can be used in place of HyperTerminal).
② Set 8051EVB’s CN2 jumper to 1 & 2, then press reset button. ③ Following Table 4.1 lists values used for session connection.
21
Table 4-1. Values for Serial Port Connection
Connection Speed 9600(bps)
Data Bit 8(bit)
Parity None
Interrupt Bit 1(bit)
Flow Control None
④ Following initial screen should be displayed after entering
values. If not, press Reset button on 8051EVB board to reset.

22
The board is now ready to run developer’s custom program using
options provided.
4.2.2. Commands for the Monitor Program
The following 5 commands are provided with 8051EVB Monitor program.
Table 4-2. Quick Reference of Commands
CMD Description
D Download program to RAM at 0x4000 (HEX파일)
F Download program to FLASH ROM
P Display Port status
R Run program from RAM
S Memory dump from 64 Byte Address
※ These commands are case sensitive. Use capital letters. ※ ‘F’ command is not supported currently.
4.2.2.1. D Command
To test HEX file during development, use this command to load program into SRAM. When D command is entered from Command Prompt, “Please Up load program (to RAM)” message will be displayed as shown below.
23
Picture 4-8. D Command Execution
To load HEX file into SRAM, you will need to use “Transfer as
ASCII” as transfer protocol. When using HyperTerminal, select “Transfer => Send Text File” to send HEX file (loopback.hex for Loopback).
24
Picture 4-9. Selecting Transfer Protocol
When file transfer is completed, “Loading complete (to RAM)” message will display, as shown in Picture 4-10. And program will return to ready mode, ready to accept next command.
25
Picture 4-10. Upload Completed
4.2.2.2. R Command This command will execute the HEX file previously downloaded
to SRAM. Picture 4-11 shows an example of program execution, once the R command has been selected. Follow instructions in “4.1.1.1 Test Environment” to complete the test.
26
Picture 4-11. R Command Execution
4.2.2.3. S Command
