@ -42,6 +42,8 @@ Highlights:
* ``PCA9548`` I2C switch class renamed to ``I2CSwitch``, to accomodate support for PCA9547, and
possibly other switches in future. Readback has been removed, and now only one channel per
switch is supported.
* 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.
Breaking changes:

@ -231,13 +231,19 @@ If you purchased a Kasli device from M-Labs, it usually comes with the IP addres
and then reboot the device (with ``artiq_flash start`` or a power cycle).
In other cases, install OpenOCD as before, and flash the IP (and, if necessary, MAC) addresses directly: ::
If the ip config field is not set, or set to "use_dhcp" then the device will attempt to obtain an IP address using
DHCP. If a static IP address is wanted, install OpenOCD as before, and flash the IP (and, if necessary, MAC) addresses
directly: ::
$ artiq_mkfs flash_storage.img -s mac xx:xx:xx:xx:xx:xx -s ip xx.xx.xx.xx
$ artiq_flash -t [board] -V [variant] -f flash_storage.img storage start
For Kasli devices, flashing a MAC address is not necessary as they can obtain it from their EEPROM.
If DHCP has been used the address can be found in the console output, which can be viewed using: ::
$ python -m misoc.tools.flterm /dev/ttyUSB2
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.
If you want to use IPv6, the device also has a link-local address that corresponds to its EUI-64, and an additional arbitrary IPv6 address can be defined by using the ``ip6`` configuration key. All IPv4 and IPv6 addresses can be used at the same time.
