Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: BOOSTXL-DRV8305EVM, MOTORWARE, DRV8301, DRV8305

Tool/software: Code Composer Studio

I tried proj_lab11e on Launchxl-F28069M and Boostxl-DRV8305EVM.

I added a potentiometer for speedRef control.

On release, I can use Hall mode and FOC mode smoothly.

On Flash, I can use Hall mode correctly (<400RPM).

But when the motor speed reached >750RPM, load current of the motor increase suddenly and motor stopps.

What's difference?, and what's happened?

Are the changes you made to add the potentiometer the same as in the HAL motorware tutorial?

Yes, I used the manual of Hardware Abstraction Layer(HAL) Module of MotorWare. Section 6.3 Adding a Potentiometer Read.
It works well.

I found one of a problem.
As I said in old thread e2e.ti.com/.../553837,

At that time I did not notice,
In release mode, the project use hal.h for BOOSTXL-DRV8305EVM correctly.
But In Flash mode, the project use hal.h for BOOSTXL-DRV8301EVM with #define DRV8301_EVM flag.
It could not solve the problem by simple "clean".

How can I solve it? Is it Ok by only to use hal.h for DRV8305_EVM flag?
Please check the problem on your environment.

I changed the include path of boostxldrv8301_refB to "${MW_INSTALL_DIR}/sw/modules/hal/boards/boostxldrv8305_revA/f28x/f2806x/src/".
I could solve it. It works fine. Thank you.
