CCS newbie easy question

Other Parts Discussed in Thread: OMAPL138

Quick question that occurs to me as I read through some of the docs while I wait for my omap l138 lcdk to arrive.

When you load a program in CCS (after you have started a debug session), is it actually flashing the nand or is it just loading the ddr ram with your program?

    For OMAPL138 it will just be loading into RAM.  For microcontroller devices with onchip flash it will automatically program the flash as well.  For external flash the boards usually come with some sort of utility to flash it.

    Regards,

    Thanks for your fast response.  I'm surprised that isn't part of CCS.  Maybe that would be a good feature for a future build.  Looking forward to my board arriving, I'm sure I'll have lots more questions once I get set up.  Thanks again.

    The trick with external flash is that it is specific to the flash chip used on the board.  With onchip flash we always know the specs and programming API and thus is more controlled.  That said we are looking and extending the flashing capability to be able to support external flash.  We would look at including support for some of our new development boards and then provide a way for people to extend it to handle other flash memory chips.

    That's very interesting.  Thanks.  Just out of curiosity (and you don't have to answer if you have more important things to do) is flashing the SD card the same story?
