C6748 .cfg file with mddr setup

Bruno Scherrer
Intellectual 820 points

Hi all,

Since my piece of code is getting bigger and bigger, I need to have the mDDR interface initialized before cint call.

I'm Using Logic's C6748 SOM and up to now I've managed tu run the app without having tuo deal with Mddr initialisation through AISgen,

Can you tell me if and where I can find an appropriate.cfg file for this module ?

Thank's in advance for your help,

Bruno

    Bruno,

    Sorry, I do not know what "cint call" is, unless this is the initial start of your program by branching to _c_int00. What exactly does this mean?

    AISgen support may be better from the Compiler Forum, but I am not sure. Sometimes it is hard to figure out where to go for the right information. But since no one answered you in a couple of days and I noticed your post, I wanted to at least get a response to you.

    I am not an AISgen expert. Is a .cfg file a standard thing that is used by the AISgen program? There should be examples of how to do the mDDR initialization through AISgen somewhere in the documentation or SDK. Have you found anything that is for other types of memories and just need to find one for your mDDR device(s)?

    Regards,

    Hi randy,

    Thank's anyway for your reply.

    You're right : cint_call stands for _c_int00.
    A .cfg file is actually a initialisation file that you can use for telling the AISgen tools which peripherals in the chip need to be initlialized before booting and how.
    You might creat youre own file (that's what I did for setting the SPI in the chip so that it can boot from it's SPI Flash memory).
    Obviously setting the mDDR interface is a bit more complicated and I wondered if there isn't any existing .cfg file for Logic's C6748 Som...

    I had another look in the Compiler Forum but with no luck. I also went through all the documentation I have.
    If by any chance you've got some news, please lett me know, in the mean time I will start studing the subject...
    Cheers,

    it looks like most of the posts concerning AISgen are in the hardware forums like this, so please continue searching here and in the TI Wiki Pages for information.
