Hi.
Now I am trying to implement Slavefifo Bulk In mode woth FPGA and FX3 Kit.
I'm followed the AN65974 example code.
In my case, I use 8bit data width. and use 100Mhz pclk from FPGA into FX3 boards.
The Problem is the slavefifo does not work.
So I need help with any hint. Please. Does anyone know how to fix?
-FPGA code ------------------------------------
always @(posedge pclk or negedge rst)
begin
if(!rst) begin
slcs_n<=1;
slwr_n<=1;
sloe_n<=1;
slrd_n<=1;
pktend_n<=1;
end else begin
slcs_n<=0;
slwr_n<= 0
sloe_n<=1;
slrd_n<=1;
pktend_n<=1;
end
end
always @(posedge pclk or negedge rst)
begin
if(!rst) begin
dq <= 0;
end else begin
dq <= dq+1;
end
end
endmodule
-Firmware code--------
I 've attached the Firmware code in here.
Basically, I followed as follow concept. Please check the Images and firmware code.
BULK IN transfer
BULK IN transfer failed with Error Code:997
What am I supposed to fix my problem to work?
I've already double checked PCLK = 100Mhz, dq is working normaly into the FX3 board.
