`ubx160_eeprom` HDL Worker

Ettus x310 UBX160 daughter board EEPROM worker.

Detail

Each UBX160 daughter board is fitted with two EEPROMs. One is associated with the RF transmit path and one with the RF receive path. Both of these eeproms are accessed using a single I2C interface. A single instance of this worker provides access to both of these eeproms. In addition to the eeproms on the UBX160 daughter board, the x310 motherboard also has its own eeprom. The mother board eeprom shares the same I2C interface with the UBX160 daughter boards and can be accessed using this same worker.

It is not necessary for the application to read the contents of the eeproms. The drc_x310.rcc Digital-Radio-Controller reads the eeprom contents, and displays the contents (at logging level OCPI_LOG_INFO=8) when the application is run.

The mother board eeprom contains the following information:

Field	Usage
revision	x310 product revision
product	product identifier
revision_compat	x310 product revision
mac_addr 0	Port 0 Ethernet MAC address
mac_addr 1	Port 1 Ethernet MAC address
gateway	IP Default gateway
Subnet Masks subnet[0] subnet[1] subnet[2] subnet[3]	Subnet masks for x310 ethernet interfaces Port 0 interface - 1 Gb Port 1 interface - 1 Gb Port 0 interface - 10 Gb Port 1 interface - 10 Gb
IP Address ip_addr[0] ip_addr[1] ip_addr[2] ip_addr[3]	IP addresses for ethernet interfaces Port 0 interface - 1 Gb Port 1 interface - 1 Gb Port 0 interface - 10 Gb Port 1 interface - 10 Gb
name	Not used
serial	PCB serial number
