hi,
this days I make some modify in usrp e310 fpga.
I want to recv my custom data and process in fpga.
so I modify the file xxx/e310/radio.v :
from:
axi_fifo_2clk #(.WIDTH(65), .SIZE(DATA_FIFO_SIZE)) tx_data_2clk_fifo
(.reset(bus_rst),
.i_aclk(bus_clk), .i_tvalid(tx_tvalid_bi), .i_tready(tx_tready_bi),
.i_tdata({tx_tlast_bi,tx_tdata_bi}),
.o_aclk(radio_clk), .o_tvalid(tx_tvalid_r), .o_tready(tx_tready_r),
.o_tdata({tx_tlast_r,tx_tdata_r}));
to:
wire custom_tvalid;
wire custom_tlast;
wire [63:0] custom_tdata;
wire custom_tready;
axi_fifo_2clk #(.WIDTH(65), .SIZE(DATA_FIFO_SIZE)) tx_data_2clk_fifo
(.reset(bus_rst),
.i_aclk(bus_clk), .i_tvalid(tx_tvalid_bi), .i_tready(tx_tready_bi),
.i_tdata({tx_tlast_bi,tx_tdata_bi}),
.o_aclk(radio_clk), .o_tvalid(custom_tvalid), .o_tready(custom_tready),
.o_tdata({custom_tlast,custom_tdata}));
my_module test
(
.valid(custom_tvalid),
.last(custom_tlast),
.ready(custom_tdata),
.data(custom_tdata)
);
when send one packet with tx_streamer->send() , data is send and recv ok!
but when I send many packet, It become stuck!! tx_streamer->send() need many
seconds to return!!
is that some flow control when send?
can I get some tips?
Thank you!
Best Regards,
Carry
