LAUNCHXL-F28027F: jumpers setting in InstaSPIN-FOC LaunchPad and DRV8301 BoosterPack Bundle

Part Number: LAUNCHXL-F28027F
Other Parts Discussed in Thread: BOOSTXL-DRV8301, DRV8301, MOTORWARE,

Dear all

I'm sorry for repeating the old question regarding jumpers setting in Piccolo. But in spite of reading many papers and watching training movies from Ti pages, jumper settings in Piccolo C2000 is still unclear for me!

My first experiments concerned simple examples related to 28027F launchpad board only.

The supply came from usb thus I have to keeep jumpers 1,2,3 connected as well as switches 1,2,3 = On; ON; ON the same with fat SW4 = ON.

Everything went good, I was able to program and play with the board.

Next stage of my project was to go to the full package - launchpad connected with the boostpack BOOSTXL-DRV8301 and the motor

I tried to go through the example   "Getting Started - InstaSPIN-FOC enabled C2000 LP - Motor BP"   from   https://training.ti.com/getting-started-instaspin-foc-enabled-c2000-lp-motor-bp

According to this example JP1 nad JP2 should be removed, (no sure... JP3 too?)  all SW 1,2,3 ON ... and also SW4 ON:

But his configuration fails, when I try to use the InstaSpin GUI...

on the other hand... in "BOOSTXL-DRV8301 Hardware User's Guide " we have:

the same in: "Motor Drive BoosterPack Quick  Start Guide: BOOSTXL-DRV8301 "

But,  I'm afraid, in this case, SW4 OFF will block the programming/ debuging of the board.

I'm afraid SW4 position is my problem... I know, it's easy to check the right position changing the configuration, but  I'm afraid that experiments with jumpers rise the risk of burning launchpoad or USB port in the PC...

Regards,

Marek

  • For the DRV8301 BoosterPack, the "Kit Readme First" guide in Motorware says to use:

    LAUNCHXL-F28027F
    i. Remove Jumpers 1, 2, 3 to isolate USB and power from BOOSTXL-DRV8301
    ii. S1 set to ON-ON-ON to allow JTAG
    iii. S4 set to OFF
    1. The QSG shows S4 set to ON
    a. ON sets the Piccolo I/Os to UART mode, which is not used by default in the example applications (only JTAG connectivity is used)
    b. OFF sets the Piccolo I/Os to GPIO mode, allowing them to drive the Fault LEDs on the BoosterPack
    2. Fault functionality works regardless of LED functionality
    iv. Provide DC bus through the BoosterPack
