How to get MicroBlaze running on Papilio Pro

fpgamicroblazespartan

I am new to the FPGA world, and there seems to be gazzilions of boards and FPGA vendors. I just bought the Papilio Pro, which is based on the Spartan 6 LX9, and although I can already bitstream basic VHDL designs, I was looking to install the MicroBlaze soft core; but there doesn't seem to exist a top-level component for the LX9. Thoughts?

Use EDK to create the design. If you don't have a BSB Wizard file for the board, you have to build it up by hand. If I recall rightly, the flow goes:

Add microblaze
Add LMB
Add BRAM controller
Add BRAM
Add UART
Add clock generator
Add reset controller
Update UCF file for Tx, Rx, Reset and Clock

Build a bitstream and then you should be able to use the SDK Wizards to build and run a Hello World app.

Then add interrupt controller & timer at least. Then you can run xilkernel (or another OS).

Followed by an external memory controller, more timers, other peripherals that take your fancy

The answer is that it is mandatory to put all unused pins to tri-state.

Close the EDK and take a look at the system.mhs file. You should see the FSL clock and reset lines connected to sys_clk. If not, you can add them straight into that system.mhs file and re-generate the bitstream.

You need two lines like this in the BEGIN/END block

BEGIN fsl_v20

  PARAMETER .... 
  PARAMETER ....

  PORT SYS_Rst = sys_rst
  PORT FSL_Clk = sys_clk

END

For a late night read, browse the FSL patent. It won't help you with your implementation, but I find it's always interesting to read up on a technology patent:
