ADS1298ECGFE-PDK: Unable to communicate via SPI

Hi,

I have some severe problems with SPI communication to ADS1298.

I am trying to read Device-ID register but I don't get any response from the device.

After power-up, I reset the device like this:

	// CS
    HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_RESET);

    // RESET LOW
    HAL_GPIO_WritePin(GPIOB, GPIO_PIN_8, GPIO_PIN_RESET);
    HAL_Delay(100);

    // RESET HIGH
    HAL_GPIO_WritePin(GPIOB, GPIO_PIN_8, GPIO_PIN_SET);
    HAL_Delay(100);

    // RESET CMD
    HAL_SPI_Transmit(&this->spi_handle, &COMMANDS.RESET, 1, 250);

	while(HAL_SPI_GetState(&this->spi_handle) != HAL_SPI_STATE_READY);

	// CS
	HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_SET);

After that, I issue SDATAC command:

	// CS
    HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_RESET);

    HAL_SPI_Transmit(&this->spi_handle, &COMMANDS.SDATAC, 1, 250);

	while(HAL_SPI_GetState(&this->spi_handle) != HAL_SPI_STATE_READY);

	// CS
	HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_SET);

And then try to read Device-ID:

	constexpr uint8_t reg_addr = 0x00;

	uint8_t opcodes[3];
	opcodes[0] = 0x20 | reg_addr;
	opcodes[1] = 0x00;
	opcodes[2] = 0x00;

	uint8_t receive;

	// CS
    HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_RESET);

	HAL_SPI_Transmit(&this->spi_handle, &opcodes[0], 1, 250);

	while(HAL_SPI_GetState(&this->spi_handle) != HAL_SPI_STATE_READY);

	HAL_SPI_Transmit(&this->spi_handle, &opcodes[1], 1, 250);

	while(HAL_SPI_GetState(&this->spi_handle) != HAL_SPI_STATE_READY);

    HAL_SPI_TransmitReceive(&this->spi_handle, &opcodes[2], &receive, 1, 250);

	while(HAL_SPI_GetState(&this->spi_handle) != HAL_SPI_STATE_READY);

	// CS
    HAL_GPIO_WritePin(GPIOD, GPIO_PIN_14, GPIO_PIN_SET);

	return (receive >> 5);

but I only receive 0x00. Any ideas what I might be missing? I already checked VCAP1 which is at 1.2V
