It is the +responsibility of the end-user to insure that it is set properly. +This file describes the standard procedure recommended by DY-4 +technical support for setting this address. This procedure is +compatible with that followed by VxWorks and is documented in +DY-4 Document Number #807885. + +EEPROM non-volatile memory of the SVME/DMV-176/177. The FFW +reserves 256 bytes of the SEEPROM for its own use and the remaining +remaining 256 bytes is reserved for OS specific information. + +Three bytes in the Serial EEPROM are used for the lowest three bytes +of the hardware Ethernet address These should be set to the serial +number of your SVME/DMV-176/177 card to ensure a unique Ethernet +address on your network. The three high bytes are hard coded in the +BSP and represent the vendor-specific Ethernet codes (0x00, 0x80, 0x7F). +Together these six bytes form the target's Ethernet address. + +NOTE: The serial number is found on the packaging (box) that the +board came in OR it is also located on the solder side of the board and +looks something like SERNO:XXXXXX. It can not be determined dynamically +by software. + +Prior to using the Ethernet controller on the SVME/DMV-176/177 for the +first time, the Ethernet address bytes must be programmed into the +Serial EEPROM on the target card. The 'emm' (EEPROM Memory Modification) +command in the General Purpose Monitor (GPM) can be used to do this. + +In this example we will assume that the serial number of the target card +is 123456. + +Start VxWorks by entering +rts <CR> +at the GPM prompt. Stop the auto-booting sequence by pressing any key. +The VxWorks prompt appears as: +[VxWorks Boot]: +Use the N command to modify the SEEPROM as follows: +[VxWorks Boot]:N +Current Ethernet Address is : 00:80:7f:5a:5a:5a +[VxWorks Boot]:N +Current Ethernet Address is : 00:80:7f:5a:5a:5a +Modify only the last 3 bytes (board unique portion) of the +Ethernet Address. +The first 3 bytes are fixed at the manufacturer's default +address block. +00 - 00 +80 - 80 +7f - 7f +5a - 12 +5a - 34 +5a - 56 +New ethernet address is :00:80:7f:12:34:56 +[VxWorks Boot]: +The SEEPROM is now programmed. + |
