* The "ip" config option can now be set to "use_dhcp" to use DHCP to obtain an IP address. * The "ip" config option can now be set to "use_dhcp" in order to use DHCP to obtain an IP address.
DHCP will also be used if no "ip" config option is set.

For Kasli devices, flashing a MAC address is not necessary as they can obtain it from their EEPROM. For Kasli devices, flashing a MAC address is not necessary as they can obtain it from their EEPROM.
Alternatively you can set the "ip" config field to "use_dhcp" to have the device use DHCP to obtain an IP address on If DHCP has been used the address can be found in the console output, which can be viewed using: ::
boot. e.g. ::
$ artiq_mkfs flash_storage.img -s ip use_dhcp $ python -m misoc.tools.flterm /dev/ttyUSB2
$ artiq_flash -t [board] -V [variant] -f flash_storage.img storage start
Check that you can ping the device. If ping fails, check that the Ethernet link LED is ON - on Kasli, it is the LED next to the SFP0 connector. As a next step, look at the messages emitted on the UART during boot. Use a program such as flterm or PuTTY to connect to the device's serial port at 115200bps 8-N-1 and reboot the device. On Kasli, the serial port is on FTDI channel 2 with v1.1 hardware (with channel 0 being JTAG) and on FTDI channel 1 with v1.0 hardware. Check that you can ping the device.
