5 | Setting the Ethernet Hardware Address |
---|
6 | ===================================== |
---|
7 | |
---|
8 | The hardware Ethernet address is not set at the factory. It is the |
---|
9 | responsibility of the end-user to insure that it is set properly. |
---|
10 | This file describes the standard procedure recommended by DY-4 |
---|
11 | technical support for setting this address. This procedure is |
---|
12 | similar to that followed by VxWorks as documented in DY-4 |
---|
13 | Document Number #807885. |
---|
14 | |
---|
15 | The hardware Ethernet address and OS configuration information |
---|
16 | must be stored in the SEEPROM non-volatile memory of the |
---|
17 | SVME/DMV-176/177. The Foundation Firmware (FFW) reserves the |
---|
18 | first 256 bytes of the SEEPROM for its own use and the remaining |
---|
19 | remaining 256 bytes are available for OS specific information. |
---|
20 | |
---|
21 | Three bytes in the Serial EEPROM are used for the lowest three bytes |
---|
22 | of the hardware Ethernet address These should be set to the serial |
---|
23 | number of your SVME/DMV-176/177 card to ensure a unique Ethernet |
---|
24 | address on your network. The three high bytes are hard coded in the |
---|
25 | BSP and represent the vendor-specific Ethernet codes (0x00, 0x80, 0x7F). |
---|
26 | Together these six bytes form the target's Ethernet address. |
---|
27 | |
---|
28 | Address is of the form ... |
---|
29 | |
---|
30 | NOTE: The serial number is found on the packaging (box) that the |
---|
31 | board came in OR it is also located on the solder side of the board and |
---|
32 | looks something like SERNO:XXXXXX. It can not be determined dynamically |
---|
33 | by software. |
---|
34 | |
---|
35 | Prior to using the Ethernet controller on the SVME/DMV-176/177 for the |
---|
36 | first time, the Ethernet address bytes must be programmed into the |
---|
37 | Serial EEPROM on the target card. The 'emm' (EEPROM Memory Modification) |
---|
38 | command in the General Purpose Monitor (GPM) can be used to do this. |
---|
39 | |
---|
40 | In this example we will assume that the serial number of the target card |
---|
41 | is 123456. |
