Flashing NAND via serial port

Alex Lifshitz
Intellectual 560 points


Hi all,
I'm trying to burn the NAND flash on our DM365 EVM (REV E) via serial port.
After erasing it (via u-boot), I tried to use the recommended application - sfh_DM36x.exe, but without success.
Maybe I do something wrong.
Here the log:

Thanks in advance for your help.

    Hi,

    I have also seen such errors while using serial flasher. I found out two solutions to this problem.

    1. Erase the NAND using the serial flasher.

    2. Just re-running the flasher has sometimes solved the issue.

    As you can see, option 1 is the more cleaner way to do it.

    IIRC, there is some weirdness in that you have to run the program twice.  Check the readme or docs.  I believe it hangs on the first attempt, then you ctrl-c out and run it again.

    Hi John,

    I have already tried this way. It still doesn't work.

    Hi,

    From where did you get the sfh_DM36x.exe you are using? Can you try with sfh_DM36x.exe from http://arago-project.org/files/releases/davinci-psp_03.01.01.38/board-utils/board-utils-davinci.tar.gz? I have tried this and it consistently works.

    Sudhakar, thanks a lot!

    This version is the same as mine (1.50), but it works.

    Not from the first try, but finally, after several retries, it burned the NAND.

    Alex.
