   It’s great to use BF537 with a PHY ( Mac) inside for IP04 upgrade.

   Jason,
   The BF537 has only built in MAC, you still need an external PHY.
   We are using one of the best PHYs DP83848 available on the market.
   Since the first BR4 is already up and running, I can tell you that overall networking speed seems to be much faster than DM9000AE based boards.
   I will blog with details very soon….
   Thx,
   Mark

   Hi Guys,

   Its a very nice job. Mark have you evaluated the cost of this new board, you think it must be cheaper than BF1 v.2 ?

   Looking forward to see this new board soon.
   Regards.

   Hi,
   The actual BOM for br4-appliance and bf1 are very close. The BR4-appliance will cost slightly more to manufacture, as you have one BGA component and 4 layer PCB (vs. 2 layer in case of BF1). You will get slightly faster board with options to go up to 128MB of SDRAM, (you need bf537 silicon rev 1.0.3 for that!!!), plus four BRI interfaces…
   Cheers,
   Mark

   Hi Mark,

   I’m so exited with all these open hardwares. I couldn’t wait to see your new board. Please let the community know about the schematic and BOM as soon as possible.

   Thanks.

   Hello,
   The schematics are already available, please see my blog about bringing up BR4-appliance. At the end you will be able to download the schematics…

   Thanks,
   Mark

   Hi mark,
   I wonder if there is anyone interested in a USB interface for USB FLASH DRIVE for voicemail storage (or general storage).

    Hi Andy,
    We provide MMC/SD card interface which is inexpensive as it uses an existing SPI bus. The USB would increase cost by several $. Please see Blackfin One design for an example of USB integration.
    Cheers,
    Mark

    Mark,

    I see a few posts up that you say the schematics are available.. I easily found the BR4-appliance ones, but I can’t seem to find the PR1-appliance schematics anywhere. This is all very exciting stuff, and I’m really anxious to be able to follow along.. Unfortunately, being in the U.S., the BRI Appliance doesn’t do me much good since BRI Is not very standard here…

    THANK YOU FOR ALL OF YOUR HARD WORK, DEDICATION AND GENEROSITY!
    Bill

    Bill,
    I will post the PR1’s schematic together with details of test results.
    Please stay tuned…
