Hi,
Amongst others I am trying to add an RFNoc axi_ram_fifo using
radio_2x64.yml to a E310 RFNoC image. But I am having a hard time to
find out which port names to use for connections and clocks.
Apparently I am using the wrong port name for dram. Or I somehow have to
add dram to the _device_
But I haven't found where all ports of _device_ are defined for each
USRP. In which file is that?
Do I have to add a dram component to the verilog?
I saw that e320_core.v has dram defined. But I am still not sure where
the dram portname is defined and how it corresponds to the dram_xxx
wires in the verilog.
I added the following to my e310_rfnoc_image_core.yml file based on the
examples I saw in e320 and x310 yml files.
noc_blocks:
fifo0:
block_desc: 'axi_ram_fifo_2x64.yml'
parameters:
# These parameters correspond to the memory interface on the E320
MEM_ADDR_W: 31
MEM_DATA_W: 64
MEM_CLK_RATE: "300e6" #TODO MDVH check if this clockspeed is
correct for E310 (copied from E320)
# Create two non-overlapping 32 MB buffers by default
FIFO_ADDR_BASE: "{31'h02000000, 31'h00000000}" #Are these
addresses correct for E310 (copied from E320)
FIFO_ADDR_MASK: "{31'h01FFFFFF, 31'h01FFFFFF}"
connections:
- { srcblk: fifo0, srcport: axi_ram, dstblk: _device_, dstport: dram }
clk_domains:
- { srcblk: _device_, srcport: dram, dstblk: fifo0, dstport: mem }
When I try to build with rfnoc_image_builder I get the error
[ERR] 1 Unresolved connection(s)
