28075 device scaling

Grant Freese

My project currently has the 176QFP F28075 designed in. My project easily fits within flash, but is too large for a RAM debug launch. The 3-minute debug launch time and two-breakpoint limit for flash builds makes development on this device rather painful.

The document SPRW261A mentions a range of parts in the delfino single core and delfino dual-core series that are pin compatible. If I drop one of those devices into my project for increased RAM during development, is a linker file change the only thing I'll need?

Thanks,


Grant

    Grant,

    Which emulator are you using now? XDS100V2 takes long time to program Flash. XDS200 would help to speed up the Flash program operation and is not too expensive.

    Also, assuming that you don't need to load code every time when you launch, try to launch the target configuration manually instead of using the bug button which would compile/launch/connect and load the code.

    Thanks and regards,

    Hi Grant,

    A few thoughts:
    1) The 3-minute debug launch/programming time is a function of the emulator you are using as much as anything.  If your board has the ability to plug in something like an xds200 emulator (and have budget to buy said emulator :) ), you can improve your flash programming time significantly.
    2) If you're using an old version of CCSv6, please note that the CCS emulation driver was improved in CCSv6.1.1 (for C2000 devices).
    3) Doing what you're thinking is feasible.  If you're planning on doing in-field flash upgrades, you may also have some minor teething things there too.  I think that's it though - it should be relatively easy to move back and forth.


    Thank you,
    Brett

    I ended up getting an XDS-560v2 emulator. It took my three minute debug launch times down to about 20 seconds. It's a huge improvement.

    Thanks for the advice.
