v5 v6 20 20 Mango has a block of MAC addresses assigned by the IEEE: {{{40-D8-55-04-20-00}}} to {{{40-D8-55-04-2F-FF}}}. We allocate two addresses from this range for each WARP v3 board. You can find your node's reserved addresses on a label on the back of the board. These addresses are also recorded in the board's EEPROM during manufacturing (see the [wiki:../EEPROM EEPROM page] for details). 21 21 22 '''Note''': early WARP v3 kits did not include this label, nor do early kits have MAC addresses in the EEPROM. '''For boards with serial numbers lower than W3-a-00110''', you can calculate your board's addresses with: 22 '''Note''': early WARP v3 kits did not include this label. These kits likewise do not have MAC addresses stored in their EEPROMs. 23 24 '''For boards with serial numbers lower than W3-a-00110''', you can calculate your board's addresses with: 23 25 {{{ 24 26 ETH A address: 40-D8-55-04-20-00 + (serial number)*2 … … 27 29 For example, for serial number W3-a-00050 the allocated addresses are {{{40-D8-55-04-20-64}}} and {{{40-D8-55-04-20-65}}}. 28 30 29 For boards with serial numbers higher than W3-a-00110 this mapping does not apply. The assigned addresses will have no relation to the board serial number. 31 We have prepared an FPGA design which will calculate these MAC addresses and store them in the EEPROM. To use it: 32 1. Download [attachment:WARPv3_MAC-Addr-EEPROM_Init.zip WARPv3_MAC-Addr-EEPROM_Init.zip]. 33 1. Connect your WARP v3 kit to power, JTAG and USB-UART, configured for 57600bps. 34 1. Configure the FPGA with the download.bit file in .zip archive. 35 1. Watch the UART output for status messages. 36 37 '''For boards with serial numbers higher than W3-a-00110''': these boards include the MAC address label and their EEPROMs are pre-programmed with the MAC addresses. For these newer kits there is no relation between serial number and MAC address. 30 38 31 39 == Hardware Constraints ==
