Modifications to the
util_ds_buf
Modifications to the MPD (Microprocessor Definition) file were necessary to
this core to allow the frequency of the connected clock to be passed to the
Xilinx EDK/XPS tool in order to derive timing constraints clocks and signals
downstream. Changes were done in accordance to Xilinx Answer Record
#42642. The Acromag design uses this core to buffer the 100MHz
differential PCIe Reference Clock to the AXI PCIe core.
Acromag modified library files
Acromag has modified two of the Xilinx supplied source files used to build a
board support package that includes the Lightweight Internet Protocol
(LWIP) library. The files are located in the folder
C:\XMC-V6\sw_source\modified xilinx library. The file names are
xaxiemacif_dma.c
and
xpqueue.c
. These files have been modified to
support multiple instances of the Ethernet interface. As delivered by Xilinx,
the library would only support a single instance of an Ethernet interface.
These files must be copied to the following directory to overwrite the
existing files delivered through the Xilinx installer:
C:\Xilinx\14.2\ISE_DS\EDK\sw\ThirdParty\sw_services\lwip140_v1_02_a\
