Choosing between TMDSCNCD28069MISO and LAUNCHXL-F28069M for InstaSPIN-FOC application

Other Parts Discussed in Thread: DRV8301-69M-KIT, LAUNCHXL-F28069M, DRV8301, BOOSTXL-DRV8301

Hello, I tried to find this answer in this forum assuming that many people go through this choice but didn't find...

I have purchased DRV8301-69M-KIT with TMDSCNCD28069MISO in it , yet I am planing to use LAUNCHXL-F28069M as controlling MCU. Same MCU chip, same InstaSPIN... What are the major differences in terms of a development as well as for basis for custom design? EVen though I will not use DRV8301, same driver part leaves few components different... probably  I/O ports ...  What about software? Is InstaSPIN-FOC exactly the same on both? Then only demo to start-up / boot is different? Thanks in advance

    "What are the major differences in terms of a development as well as for basis for custom design?"
    Regarding the 69M controlCARD vs. Launchpad, the differences are minor in re-using for your own design. I think the controlCARD is a bit more battle hardened and proven. For the inverter side, the BOOSTXL-DRV8301 is a superior hardware layout to the DRV8301 EVM, particularly in regards to current sense. I recommend following more of what was done on the BOOST.

    " Is InstaSPIN-FOC exactly the same on both?"
    Yes. The proj_lab##.c are identical. The only files that change are the hal.c/.h (interface to all peripherals) and user.h (interface to the control system where hardware/software scaling is required).

    The BOOSTXL-DRV8301 + Launchpad gives better performance due to the current sense layout.

    "Then only demo to start-up / boot is different?"
    I don't follow this question. The DRV8301 EVM does off the Demo GUI www.ti.com/.../motorkitscncd69miso which is not available for the Launchpad + BoosterPack. From the HW perspective it's simply a matter of connectors and how the pins are brought out to a header or a DIMM slot.
