2.5 FLASH Programming
In addition to the microSD card available on the front panel and the embedded
eMMC (not supported as primary boot device in the design) the board hosts 2
redundant sets of serial flash memories. One set is dedicated to the Main FPGA (Zynq
Ult) and one to the secondary FPGA (Spartan 7). The selection of which of
the 2 devices available for each FPGA will be used during the configuration process is
controlled by the MMC Stamp SoM (see FPGA boot mode selection). The Flash
memories can be accessed through the same device they will program using the JTAG
interface and a supported programming device/tool connected to the on-board JTAG
connector or MicroTCA JSM (JTAG Switching Module) or they can be accessed for
in-chassis programming by the MMC Stamp through IPMI instructions (HPM.1,
Hardware Platform Management).
2.6 White Rabbit Support
The board provides most of the necessary infrastructure needed to implement a
White Rabbit End Point. The interconnections required to implement the missing
features are made available on the front panel high density connector whose pin-out is
described in High Density microHDMI type-D section). A breakout board with an
SFP/SFP+ interface has to be connected to the high-density connector to complete the
set of required components of a White Rabbit endpoint. Alternatively, port 1 on the
MicroTCA backplane could be used for this purpose although this is not the preferred
method and might require an additional MCH.
The firmware needed to operate the White Rabbit End point on the DAMC-
FMC2ZUP can be derived from the OpenHardware Cute-WR project (information
available on ohwr.org
). The firmware customization required will later on be made
available under the OpenHardware license terms.
