Flashing Tools Guide

I am following this guide in order to flash U-Boot to NAND:

http://processors.wiki.ti.com/index.php/DM816x/C6A816x/AM389x_PSP_Flashing_Tools_Guide

but have come across several obstacles in getting it to work with my DDR2 board.

The first issue was that the "ti816x_ddr.gel" file it says to use is actually for DDR3 not DDR2 (I still have the old EVM and am waiting for the new EVM to arrive). I downloaded "evm816x.gel” from http://support.spectrumdigital.com/boards/netradimm/revc/
as this seemed the next best thing.

Now when I go to "Scripts" in CCS, there is no "NETRA External Memory -> do_all" option. What should I do instead?

Thanks,
Ralph

    Ralph,

    If you open the GEL file made for DDR3, you can comment out the DDR3 section and un-comment the DDR2 section. These changes will make it work for DDR2. Once a proper GEL file is used, you will get the "NETRA External Memory -> do_all" option.

    Regards,

    Okay, the GEL file is happily loaded. I am now having problems with the next stage.

    The flashing document says to load "host-tools/nand-flash-writer.out". First of all, this isn't present in EZSDK 5.00.00.56 so I obtain it from 5.01.00.77 and run it.

    When it is run, no prompt appears as the document suggests and instead I get an error message saying: "Can't find a source file at "D:/Netra/nand-flash-writer/src/main.c"".

    Please tell me where this file is as I can't find any equivalent file in the EZSDK.

    Thanks,
    Ralph
