MCSDK v6.3.2 It looks like the STM32 is failing to PWM fet gates and that's resulting in high current and an Under Voltage fault.I made a board with the STM32G431RBT6 and DRV8323 driver chip. I've used the DRV chip in another board for a long time wi...

I'm trying to make a custom board project with Board Designer and found the documentation lacking for entering the correct parameters. The Bus Voltage Divider needs to be equal to 1/(voltage divider ratio). Also, the resistors on the Board Designer a...

I'm trying out the board designer feature and ran into an issue where after succesfully making a board in Board Designer based on a custom STM32G431 motor controller board, MCWB gives this error about the current sensing not being found:The Board Des...

I found that 4 of the pwm signals were swapped around. After changing them to their correct connection I'm running into low voltage faults. But I'll post that on another thread.

Here are some plots from trying to spin the motor. The rotor stays stationary the whole time. Here are some logic analyzer shots of the 6 mosfet PWM pins:And here is the corresponding scope shot at 16kHz: I can rotate the motor to get other patterns...

Thank you for the support @Gael A . Hopefully ST will make these tools a little easier to use in the future. Perhaps a video walk-through of using the Board Designer (along with how to address any common mistakes) with a custom board would be helpf...

Thank you @Gael A for the thoughtful response. I spun up a new board with all current sensing on a single channel (ADC1). However, now I'm running into other issues:Quadrature encoder does not appear in MCWB, even though it's selected. Even after ...
