FSL_M_CLk and FSL_S_CLK lost in EDK 11.3 when importing the IP.

[bithuxiaoming]

I'm trying to use the ip windward to create a fsl ip without modifying any parameter and import it into the edk project,

however it report the FSL_M_CLk and FSL_S_CLK are lost, the pao is list as below: will anyone can help me on

this problem? Thanks for your help.

Hi,

Looks like CIP was not able to automatically map FSL_M_CLK and FSL_S_CLK.

So we need to modify the HDL or manually select our ports.

Thnx

So will you please tell me how to correct the hdl file or where can I manually select the ports. Because in the CIP

when it report the error it halts.

Even the CIP report error, and it seems that the IP is import into the project. and the port is connecting as the picture,

however, when I test the FSL IP as the default vhdl, it seem the accumulater doesn't work correctly.

Thanks.

Hi,

Are you using the FSL in Synchronous mode or Asynchronous mode?

FSL_CLK is the input clock to the FSL bus when used in the synchronous FIFO mode (C_ASYNC_CLKS = 0). The
FSL_Clk is used as the clock for both the master and slave interfaces

FSL_M_CLK  port provides the input clock to the master interface of the FSL bus when used in the asynchronous FIFO mode
(C_ASYNC_CLKS = 1).

FSL_S_CLK port provides the input clock to the slave interface on the FSL bus when used in the asynchronous FIFO mode (C_ASYNC_CLKS = 1). 

If you are using Asynchronous mode, let us know the procedure of importing this FSL.

Thnx

I'm having the same problem trying to import an FSL peripheral in 12.3 :

"The Wizard was not able to automatically map all bus interface ports for MFSL. Please manually select your ports or modify your HDL file."  It can't find the FSL_M_Clk. Same with the FLS_S_Clk. I've checked the HDL, the ports exist!

Where do I have the option of specifying whether the FIFOs work in synchronous or asynchronous modes, if that is the problem? There was no such option when creating the FSL based peripheral...

Hi,

Importing this peripheral into EDK system:-

1, Go to Hardware => Configure Co processor

2, You will be able to see the created peripheral

3, Select the peripheral and use the Add button to include it into the system. Once this is done, Click OK.

4, Once this is done, you will be able to see the peripheral being connected to FSL bus.

 Thnx

Just want to clarify one thing, you don't need to import a custom peripheral after creating one. To use the core in XPS, just put it into pcores directory after creating it will be sufficient.

The Import Wizard is helpful if you have changed the HDL code of  your custom peripheral and you want the Wizard to update the MPD, PAO, etc. supporting files automatically. You don't have to use it if you know how to manually update those supporting files.

Actually, the problem seems to have been a mistake in the direction of the clocks FSL_M_Clk and FSL_S_Clk when the Create or Import Peripheral wizard is used. In Xilinx 12.3 both these clocks are output ports when they should have been input ports - someone else mentioned this in the forums in some post that I can't locate now. It worked when I changed the direction of the ports.

This has been fixed in version 12.4 of EDK.
