Part Number:BOOSTXL-DRV8305EVM
I switched from BOOSTXL-DRV8301 to BOOSTXL-DRV8305EVM because I need a little more power.
Everything worked fine on the 8301, except for the detail with too few power resources. On the DRV8305EVM I have the problem that the motor is not rotating properly. When I read the signals, it doesn't look very good either.
I am used to such signals from the DRV8301 board:
Now with the DRV8305 it looks like this (same svpwm signals):
I am using the 3-PWM-Signal Configuration. I also tried various configurations in the SPI register. Without success. What may be the problem? I noticed that the motor currents are partly identical, which I do not understand.
