STM32U585QI SPI Issue

Hi,

I have successfully configured the SPI1 with following parameters and trying to transfer a single byte but it is being timed-out in HAL_SPI_Transmit as EOT is not being set.

Init.Mode = SPI_MODE_MASTER;

Init.Direction = SPI_DIRECTION_2LINES;

Init.DataSize = SPI_DATASIZE_8BIT;

Init.CLKPolarity = SPI_POLARITY_LOW;

Init.CLKPhase = SPI_PHASE_1EDGE;

Init.NSS = SPI_NSS_SOFT;

Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_256;

Init.FirstBit = SPI_FIRSTBIT_MSB;

Init.TIMode = SPI_TIMODE_DISABLE;

Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;

Init.CRCPolynomial = 0x7;

Init.NSSPMode = SPI_NSS_PULSE_DISABLE;

Init.NSSPolarity = SPI_NSS_POLARITY_LOW;

Init.FifoThreshold = SPI_FIFO_THRESHOLD_01DATA;

Init.TxCRCInitializationPattern = SPI_CRC_INITIALIZATION_ALL_ZERO_PATTERN;

Init.RxCRCInitializationPattern = SPI_CRC_INITIALIZATION_ALL_ZERO_PATTERN;

Init.MasterSSIdleness = SPI_MASTER_SS_IDLENESS_00CYCLE;

Init.MasterInterDataIdleness = SPI_MASTER_INTERDATA_IDLENESS_00CYCLE;

Init.MasterReceiverAutoSusp = SPI_MASTER_RX_AUTOSUSP_DISABLE;

Init.MasterKeepIOState = SPI_MASTER_KEEP_IO_STATE_DISABLE;

Init.IOSwap = SPI_IO_SWAP_DISABLE;

Init.ReadyMasterManagement = SPI_RDY_MASTER_MANAGEMENT_INTERNALLY;

Init.ReadyPolarity = SPI_RDY_POLARITY_HIGH;

I have tried many different combinations but no success so far.

I have sourced the SPI1 by RCC_SPI1CLKSOURCE_SYSCLK and my I2C peripheral on RCC_I2C1CLKSOURCE_PCLK1 is working so I am expecting SYSCLK to be correct. I have also enabled the SPI clock in HAL_SPI_MspInit

That would be great if you could help me with this.

Thanks in advance,

Ramin
