    Used the Cypress CY7C68013A EZ-USB FX2LP USB2.0 Developement Board/module which is also used for the vu boxes, and using BroadbandStudio 3.1

    The main objective is to reach the Dreambox 800se / 500hd via the SCL / SDA method.
    Just for the fun, and maybe it's useless, but it would be nice if it succeeded.


    First thing to known is, if both boxes have a SCL/SDA connector, so this I have examined and found.
    It's the P801 connector on both motherboards.
    Just measure the ground pin, next to it is SDA, and then SCL.
    The other is the 3vdc pin, but this is not needed.


    Image 500hd see this,

    [​IMG]

    And for the 800se, see this image,

    [​IMG]

    Okay, so far so good.

    BroadbandStudio 3.1 connection story.
    This is another story because the bbs has no drivers for the bcm97405 CPU, but for the bcm97413.
    These are almost identical, so too works an bcm97413 cpu fine on the 800se / 500hd board.
    So most logical is to use the bcm97413 drivers, but unfortunately, it will not connect.


    [​IMG]

    Then I had the idea to edit all the 7413 references, in the bcm97413 files, to 7405, which gives a better result, it now connects with the motherboard, but when choosing the bcm97405 drivers gives an update error, so something is still wrong.

    [​IMG]

    But okay, it's connected, that's the good part.

    [​IMG]

    But still, it's useless because of the errors, as the Video tool, or flash tool.
    [​IMG]

    So, editing the files needs to be further investigated.
    To be continued ....?

    UPDATE...
    I started all over with the bbs software because I did it on the wrong way.
    I only needed to make a copy from the Bcm97413.device file and change the,

    <device name="Bcm97413" type="Broadcom.Driver.ReferenceBoard.Bcm97413">
    to
    <device name="Bcm97405" type="Broadcom.Driver.ReferenceBoard.Bcm97413">


    And save it as Bcm97405.device to the Broadcom Driver map.
    After that it works flawless, you can choose between the Bcm97413 or Bcm97405, both are connected.


    Nand flash rom scripts.

    For the DM800SE and DM500HD there were no scripts present in the bbs,
    So I have made them myself.
    I made them for Hynix HY27US08121A and HY27US08121B, but in fact both are equal.

    It looks like this..
    Code:
    <?xml version="1.0" encoding="utf-8"?>
    <Flash maker="Hynix" name="HY27US08121A" type="NAND" technology="SLC">
      <Command type="Nand" programmode="Block" maxbyte="512"/>
      <ID>
        <Maker maxbyte="1" offset="0x00">0xAD</Maker>
        <Device maxbyte="1">
          <DevId offset="0x01">0x76</DevId>
        </Device>
      </ID>
      <Size unit="mbit">512</Size>
      <Sector uniform="true" secure="false">
        <MaxSector>4096</MaxSector>
        <Size unit="kbyte">16</Size>
      </Sector>
    </Flash>
    
    These must be placed in the Broadcom Flashes folder.
    You can find it in the zip file, including the Bcm97405.device file.
    Broadband Studio 3 Bcm97405.zip

    Steps...
    Assuming the software is installed.

    1. Download the zip file
    2. Copy the Bcm97405.device file to the c:\Program Files\Broadcom\Broadband Studio 3\Drivers folder.
    3. Copy the Hynix HY27US08121A.xml and Hynix HY27US08121B.xml files to the c:\Program Files\Broadcom\Broadband Studio 3\Flashes folder.
    4. Connect your Cypress board SCL/SDA/GND wires to the 800se or 500hd box, see picture for the I2C connections.
    Vcc is not needed.

    5. Connect the Cypress usb cable to your computer and switch it on.
    6. Switch on the dreambox.
    7. Start the Broadband Studio 3 program and see the device list etc.

    Good luck....

    Okay, than I have some another idea's..
    BBS, erase nand flash, upload the boot loader on the regular way, an make a backup with BBS.
    Or,
    I have one 800se with a tsop48 nand chip socket.
    I remove the nand chip, erase it, put it back on the 800se, flash the boot loader, and make a backup with my nand chip programmer.

    I shall see if I find the time this weekend to do it.

    Johnny ,what will you find out by flashing the boot loader to a NAND you previously deleted?
    How will you find out the starting address, that BBS requires ,by doing that procedure you described?
    I do not think, the doing backup will solve the problem of unknown starting address. Or am I wrong?
