MCF8329A: Cannot get motor spinning on custom hardware

Tool/software:

Hi,

I am trying to get going with a motordriver based around mcf8329a. However there seems to be a few issues in my setup. 

I have bought and tested everything with ti:s evaluation board for this device, and it is really working well with my motor. I have tuned and exported all the settings in a json.

Now however I am trying the same code on our own hardware and I am getting no expected results. The motor does not start spinning. Once scoped the phases ABC I can see that the driver is doing something, beginning with switching the phases with a 50kHz square on all phases, but after that nothing, no movement, no faults reported or anything. So I am a bit stuck. Do you have any idea of what could be the issue?

I have communication and I can talk to the mcf8329a, but I cannot get the motor turning over. I am using Arduino as a test platform.

Theese are my register settings;

I am interested in how startup and speed command is set over i2c with the evaluation kit. Which pins are asserted high/low to startup? 

I have tried to clear all faults, but no difference.

This is my code for setting speed;

// Function to set the motor speed using ALGO_DEBUG1 register
void setMotorSpeed(uint8_t address, uint16_t speed) {
    // Read the current value of ALGO_DEBUG1 register (address 0xEC)
    uint32_t currentValue = MCF8329AReadRegister(address, 0xEC);

    // Modify the SPEED_OVER_RIDE and DIGITAL_SPEED_CTRL fields
    currentValue |= 0x80000000; // Set SPEED_OVER_RIDE to 1 (bit 31)
    currentValue &= ~(0x1FFFF << 16); // Clear DIGITAL_SPEED_CTRL bits (30-16)
    currentValue |= ((speed & 0x1FFFF) << 16); // Set DIGITAL_SPEED_CTRL bits (30-16)

    // Split the modified value into bytes
    uint8_t byte4 = (currentValue >> 24) & 0xFF;
    uint8_t byte3 = (currentValue >> 16) & 0xFF;
    uint8_t byte2 = (currentValue >> 8) & 0xFF;
    uint8_t byte1 = currentValue & 0xFF;

    // Write the updated value back to ALGO_DEBUG1 register
    MCF8329AWriteRegister(address, 0xEC, byte4, byte3, byte2, byte1);
}

I am not sure if this is the correct way to set the motor rpm. Seems odd that it is a debug register.

Any help appreciated!
