OC8051 working with BRAM
I was able to synthesize a design with BRAM and am able to update the contents of the BRAM/ROM in the bitstream. Now for testing with actual hardware tomorrow.

Porting OC8051 processor to Butterfly Platform.
I’m working on porting the OC8051 project from OpenCores to the Butterfly Platform. The ultimate goal is to have a core that supports a c compiler like gcc or sdcc and that supports wishbone for easily connecting Wings. I’ve got the design synthesizing but am running into trouble with the ROM. It appears that the…

It’s been quiet at Gadget Factory.
I know its been quiet at Gadget Factory but I have been working overtime to develop a modular system to plug a suite of peripherals into the Butterfly Platform hardware. The designs have been sent off to the board house and there will be a slew of activity on the website very soon. The modules…

Version 2.0 of the Spartan 3E Cocoon was submitted to board house.
Version 2.0 of the Spartan 3E Cocoon was submitted to a board house today. It should arrive within 7-10 days and take a couple more days for verification. This new version adds SPI Flash so designs can work independently of a computer. It also implements the new Butterfly Bus which is designed to allow peripheral…

Revision 2.0 of USB and S3E Cocoons.
Phew, Still working on revision 2.0 of the USB and S3E boards and the Butterfly Platform specification. It’s taking way longer then I was thinking it would. On a side note, I looked through the Logic Analyzer source code and commented out the XON/XOFF code that is most likely limiting the speed to 38400. Next…

Working on revision 2 of the USB Cocoon and the S3E Cocoon
Revision 2 of the USB board follows the new Butterfly Specification and implements a 16 Cocoon Bus. Most pins from the FTDI2232 are routed to the 16 Bit Cocoon bus to allow more flexible use of the FT2232 chip. A mini-USB footprint is also implemented. Revision 2 of the S3E board implements SPI flash to…

FPGA Wiki is running and building more boards today.
The new FPGA Wiki is up and running at http://wikis.gadgetfactory.net/index.php/FPGA_Wiki. The neat thing is that it allows screencasts to be recorded and embedded directly from the Wiki. I also need to build more boards today. So the rest of the day is going to be spent doing that. I did get some time to work…

Trying to add Jabber and MediaWiki to GForge today.
Will be working on adding Jabber and MediaWiki to the website today. Collaboration is a crucial part of Gadget Factory so I am going to take some time to improve the collaboration tools available. Hopefully it will only take half a day and then I will FINALLY be able to work on the Butterfly Spec.…
