Re: Download & Run Image through EtherNet.

Hello Zubair,

I think that 2440 board u must have got must be having a Porting Guide
or a Readme. I think it wud be a good suggestion to just peek into it.
It might give u some more insights.

Just my suggestion, there will be a menu item in the EBOOT menu for
marking the bad blocks. I think u might have just missed it. Please
check it.

So u need to follow the sequence
1. Erase All blocks and then download the Steploader + EBOOT
combination (u might need to do it only once)
2. Boot up and Halt the EBOOT
3. Mark the Boot Blocks Bad (can be done by 2 options a. marking them
bad b. formating the flash)
4. Download the image and le it boot up....

After this procedure try booting up the board and then loading the
image. I reckon it might solve u'r problem.

 Hi Friends.
 I am working in WinCE 5.0 , and samsung jtk2440 board. Now I want to
download the image and configure it by ethernet. After proper changing i m
able to do my work correctly. I use Nboot to boot from nand-flash. The
problem is that when i Reboot the board after configuring and burning image
on nandflash, to launch the existing image, the control goes to the " BOOL
BP_ReadData()" function of the " bootpart.cpp" file. In the  Loop given below
the board stucks and don't boot.

while (dwNumSects--)
       dwBlockAddress = (dwSectorAddr / g_FlashInfo.wSectorsPerBlock);

       // If the block is marked bad, skip to next block.  Note that the
assumption in our error checking
       // is that any truely bad block will be marked either by the factory
during production or will be marked
       // during the erase and write verification phases.  If anything other
than a bad block fails ECC correction
       // in this routine, it's fatal.
       if (IS_BLOCK_UNUSABLE(dwBlockAddress))
           dwSectorAddr += g_FlashInfo.wSectorsPerBlock;
           ++dwNumSects;        // Compensate for fact that we didn't write
any sector data.

       // Read the sector - if this fails ECC correction, we fail the whole
read operation.
       // Note - only single sector reads supported at the moment..
       if (!FMD_ReadSector(dwSectorAddr, pbBuffer, NULL, 1))
           RETAILMSG (1, (TEXT("ReadData: failed to read sector (0x%x).\r\n")
, dwSectorAddr));

       pbBuffer += g_FlashInfo.wDataBytesPerSector;


I can't understand what is the problem, and why it stucks here.
              Is there any registry settings also for using ethernet??? up
to now i did not change any thing in the registry.
Can any Body help/Guide me to solve this problem.

           Thanx to ALLLL.............and waiting for any suggestion.
