Papilio Pro bscan bitfile source code?

4 posts in this topic

I'm trying to build the ./bscan_spi_xc6slx9.bit file from source, to program the flash on my Papilio Pro board.                                            
                                                                                                                                                           
From the git source, the only .v or .vhdl source file for Spartan 6 is:                                                                                    
  ./xc3sprog/trunk/bscan_spi/bscan_s6_spi_isf_ext.v                                                                                                        
Is this the one I should use?                                                                                                                              
                                                                                                                                                           
Then for the User Constraints File, the only relevant one I can find is the generic one,                                                                   
    
                                                                                                                                                           
The two files obviously don't match, so I from the .ucf file I removed everything                                                                          
except the FLASH_* lines.
And in the .v file, I replaced all the MOSI/MISO lines with the FLASH_SI/SO etc lines, like:
module top
  (
   output wire FLASH_SI,  //MOSI,
   output wire FLASH_CS, //CSB,
   output wire FLASH_CK, //DRCK1,
   input  FLASH_SO //MISO
   );
(and all other places)

The resulting .v & .ucf files do generate a bscan .bit file, but when I use that to program
the flash, I get this:

./papilio-prog -f ../Helper_App/Quickstart-Papilio_One_LX9-v1.5.bit -b ~joostje/VHDL/bscan-Papilio/top.bit -v
Using built-in device list
JTAG chainpos: 0 Device IDCODE = 0x24001093     Desc: XC6SLX9

Done.

Using the original bscan_spi_xc6slx9.bit does work:


As for the reason why I want to build the source (apart from "I should be able to"),
I'm using a modified Papilio board design with a Spartan XC6SLX16 (256 pin BGA),
So I need to generate a new bitfile for that XC6SLX16.

So, doesn anyone know where the .v or .vhdl source files (preferably with a .ucf file) are that
can generate a .bit file for the Spartan 6 (Papilio Pro)?

Papilio-Loader source was this morning cloned from here:
  https://github.com/GadgetFactory/Papilio-Loader.git

 

(I've attached my modified .ucf and .v files, both renamed to .txt as the uploader didn't like my .ucf extention)

Thanks,
joost

papilio-prog is not the same as xc3sprog.  papilio-prog was forked off from xc3sprog way back and is using a different bscan file.

I have attached  a zip file with the vhdl source file as well as the ucf file for the qfp144 package.

 

Hope this helps,

Magnus

Thanks Magnus!

 

Yes, the .vhd and .ucf files you provided do work.

 

I do know papilio-prog uses a different bscan file, but somehow I couldn't find any other .vhd or .v files in the papilio-prog source code.

I now see that the file you sent is actually present in the git repository (although the one from git looks like an older version), so

I apologize.

 

Thanks for the quick help!
