Hi Ilandre and Kurt,

I need to download my Spartan 3 by using uboot and I was wondering if
someone had already written something for that.
I found your mails but unfortunately not the patch. :(
This patch will be added to the next uboot version ?? Where can I find it ?
Thanks in advance.

Best Regards
Nicolas Colombain (Armadeus Project)

I've just implemented Spartan-3 download using the existing Spartan 2 
driver. Actually, it required no changes. You simply need to add 
definitions for new image sizes to include/spartan2.h (though even that 
is not mandatory).

I was thinking about doing some cosmetic changes later, like replacig 
references to Spartan-II with "Spartan family" or something, but so far 
had no time nor lots of desire to do that.

Unfortunately, I won't have access to that source until the weekend, but 
since the change is trivial, you should have no problem at all.

BTW, the same seems to be  true about the new FPGAs from the Virtex 
family: the download procedure is still the same.

Happy hacking,
Vladimir

Hi Nicolas,

I used the patch provided by Kurt Stremerch (see attached file).
However I was not able to make the "fpga loadb" command to work while
"fpga load" works fine.
Then I applied the patch posted by Andrew Dyer to the mailing list but
loadb still did not work (for me this is not a problem).



HTH,

Hello,

>Thanks for the file!

you're welcome.

>What the problem with the loadb command ?

IIRC loadb did not parse the header correctly.

>and what is
>the difference between the loadb and load ?

loadb gets a .bit file while load gets a .bin file.
.bin file is the pure bitstream while .bit = <header> + .bin.
The header provides information about bitstream name, creation date etc.
