DAC8563: STM32H7 SPI problems

Hello! I tested my DAC8563 on a STM32H743 but it doesn't work (0V on A & B Channels)...

So I tried with an Arduino UNO and it's OK.
Times ago I used different STM MCU without problems (F4, F7).

This is STM SPI initialization code:

void MX_SPI1_Init(void)
{

  hspi1.Instance = SPI1;
  hspi1.Init.Mode = SPI_MODE_MASTER;
  hspi1.Init.Direction = SPI_DIRECTION_2LINES;
  hspi1.Init.DataSize = SPI_DATASIZE_8BIT;
  hspi1.Init.CLKPolarity = SPI_POLARITY_LOW;
  hspi1.Init.CLKPhase = SPI_PHASE_2EDGE;
  hspi1.Init.NSS = SPI_NSS_SOFT;
  hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_128;
  hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;
  hspi1.Init.TIMode = SPI_TIMODE_DISABLE;
  hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
  hspi1.Init.CRCPolynomial = 0x0;
  hspi1.Init.NSSPMode = SPI_NSS_PULSE_DISABLE;
  hspi1.Init.NSSPolarity = SPI_NSS_POLARITY_LOW;
  hspi1.Init.FifoThreshold = SPI_FIFO_THRESHOLD_01DATA;
  hspi1.Init.TxCRCInitializationPattern = SPI_CRC_INITIALIZATION_ALL_ZERO_PATTERN;
  hspi1.Init.RxCRCInitializationPattern = SPI_CRC_INITIALIZATION_ALL_ZERO_PATTERN;
  hspi1.Init.MasterSSIdleness = SPI_MASTER_SS_IDLENESS_01CYCLE;
  hspi1.Init.MasterInterDataIdleness = SPI_MASTER_INTERDATA_IDLENESS_02CYCLE;
  hspi1.Init.MasterReceiverAutoSusp = SPI_MASTER_RX_AUTOSUSP_ENABLE;
  hspi1.Init.MasterKeepIOState = SPI_MASTER_KEEP_IO_STATE_DISABLE;
  hspi1.Init.IOSwap = SPI_IO_SWAP_DISABLE;
  if (HAL_SPI_Init(&hspi1) != HAL_OK)
  {
    Error_Handler();
  }

}

After connecting a signal analyzer to H7 and sending init commands, I had:

//...

	HAL_GPIO_WritePin(SYNC_DAC8563_GPIO_Port, SYNC_DAC8563_Pin, GPIO_PIN_SET);
	dac_reg_write(0x28, 0x0001); //reset DAC
	dac_reg_write(0x20, 0x0003); //power_up DAC
	dac_reg_write(0x38, 0x0001); //internal ref
	dac_reg_write(0x02, 0x0000);//gain a x 2, b x 2
	dac_reg_write(0x30, 0x0003); //deactivate load trigger
//...

I checked supply voltage levels and all seems ok...
Can someone help me?

Thanks a lot and best regards,
Mario
