I am using EVB NUCLEO-H503RB with I3C Target feature.
I have successfully assign a dynamic address (0x50) to this I3C Target:
Below are my configure, is there anything missing for responding the address?

Hi @KHALSI_Foued ,
I have some new discover.
I found my I3C Target could ACK to the I3C Controller.
But it could not response correctly to the Legacy I2C Controller, even both of them are sending same signal:
Is there any way to fix it?
By the way, below are my code for I3C Controller:
/* Context buffer related to Frame context, contain different buffer value for a communication */
I3C_XferTypeDef aContextBuffers[3];
/* Array contain targets descriptor */
TargetDesc_TypeDef *aTargetDesc[1] = \
{
&TargetDesc1, /* DEVICE_ID1 */
};
/* Descriptor for private data transmit */
/* Buffer used for transmission */
uint8_t aTxBuffer[2] = {0};
uint8_t T_aTxBuffer[0xFF] = {0};
/* Buffer used for reception */
uint8_t aRxBuffer[0xFF];
uint8_t T_aRxBuffer[0xFF];
uint64_t Dyn_aRxBuffer[0xFF];
/* Buffer used by HAL to compute control data for the Private Communication */
uint32_t aControlBuffer[0xF];
I3C_PrivateTypeDef aPrivateDescriptor[2] = \
{
//Controller Read Write
{TARGET1_DYN_ADDR, {aTxBuffer, 2}, {NULL, 0}, HAL_I3C_DIRECTION_WRITE},
{TARGET1_DYN_ADDR, {NULL, 0}, {aRxBuffer, 2}, HAL_I3C_DIRECTION_READ},
};

/* USER CODE BEGIN 1 */
/* USER CODE END 1 */

/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();

/* Enable Interrupt for Dynamic Address Assignment on I3C Target */
HAL_I3C_ActivateNotification(&hi3c1, NULL, HAL_I3C_IT_DAUPDIE);
/* Handle Dynamic Address Assignment (Applying CCC 0x07 to I3C Bus) */
HAL_StatusTypeDef result = HAL_ERROR;
HAL_I3C_Ctrl_DynAddrAssign(&hi3c2, Dyn_aRxBuffer, I3C_ONLY_ENTDAA, 100);
result = HAL_I3C_Ctrl_SetDynAddr(&hi3c2, TARGET1_DYN_ADDR);
LL_mDelay(2);
/* Prepare Transmit context buffer with the different parameters */
aTxBuffer[0] = 0x80;
aTxBuffer[1] = 0xCC;
aContextBuffers[0].CtrlBuf.pBuffer = aControlBuffer;
aContextBuffers[0].CtrlBuf.Size = 1;

LL_mDelay(10);
