CCS 4 under Windows -- what's the purpose?

MATT GESSNER
Expert 1435 points
Other Parts Discussed in Thread: AM3505

We're using the 3505.  Why does it seem like TI sells CCS4 for no reason?  The PSP for the 3505 doesn't seem to be compatible with it.  It's all about linux.

Well, what if we don't want to use linux for the target or the host, but we still need the loader?

What are people using CCSv4/Windows for?  Windows CE development?  How come no one mentioned that to us during the sales process?

I'm more than dissatisfied with the lack of responses from TI employees to my last question.  15 reads and no responses toit.

Why even sell products if you're not going to support them?  What's the point?

Theoretically, by not having a staff of people ready to answer the phone, you save money: you let the community answer questions.  This isn't a good way to make customers like your services.

Any TI person want to enter into a dialog about this?

    Matt,

    The AM35x PSP and included xloader are Linux products.  Building xloader is provided through a make file which is explained in the PSP User's Guide here: http://e2e.ti.com/support/dsp/sitara_arm174_microprocessors/f/416/p/87185/301241.aspx#301241.  That said is there is no CCS proj file for xloader. 

    To better help you, can you clarify why you need xloader or what exactly you are trying to do?  Are using using an RTOS or no OS?

    Regards,

    Kevin Chalmers

    Code Composer Studio support a larger number of processor devices from TI than just being able to support the AM3505.  Your specific environment that you mention, AM3505 and Linux is not one where Code Composer Studio is suited for.

    Agreed for the Linux PSP.  There are other toolchains associated with Linux development that are used.

    At this point, there are other RTOS options from our partners that you could interact with including WindRiver, QNX, etc.  What TI does not have currently is a stripped down, no-OS centric software support package.

    No, development with Windows CE requires Microsoft Visual Studio with Platform Builder as mandated by Microsoft.

    Thanks for your response.

    Given that xloader is a generic piece of software, why WOULDN'T we use it to load stuff off SD cards or something similar?  That's the whole point, right?  It's very much OS-agnostic.

    We're not using an OS.  We don't need one.  What we need is horsepower.

    Kevin,

    My apologies since my last reply didn't answer one of your questions.

    I want to load a piece of software I'm writing from SD card.  It's part of our field-upgrade capability for the product (put in an SD card, reboot the unit, load the software on the SD card and let it perform an upgrade).

    Given that xloader already handles initializing memory and such, it seemed like the tool to use to get things started.  I know it loads u-boot for linux, so it seemed natural to allow it to load our image as well.

    This doesn't seem like a big stretch to me.  I'm having trouble figuring out why a basic, basic piece of software is only supported for one kind of application image.

    Thanks,

    Matt

    Matt,

     

    Understood.  There is a BSL (low level test code) accessible through Logic's website (link is below) that allows initializes the AM35x and allows you read/write the SD.

    Kevin,

    Thanks, this seems like it will be very helpful.  I will let you know when I've had a chance to absorb what's in it.
