Hi, I just accidentally modified the PRODUCT_STATE to provisioning and not able to recover.So, I tried to do the OBKey Provisioning and use DA to regression back to Open State.I've created my OBKey:However, provisioning always failed.Is there any oth...

We are trying to use software "STM32 st-link utility" to program stm32h563 series MCU.However, it could not recognize our target MCU and shows "no target connected".Stm32h563 Target not connectedThe SWD pin connections are correct, we are able to do ...

I am using NUCLEO-H503RB as I3C Target with LL library.What's the minimum size of TX-FIFO available when I3C Target is reading by Controller?I setup I3C Target TX-FIFO using function "LL_I3C_ConfigTxPreload" with 1 byte, but it always runs 8 bytes pe...

I am using EVB NUCLEO-H503RB with I3C Target feature. I have successfully assign a dynamic address (0x50) to this I3C Target: However, I could not get ACK from this Target with Address 0x50: Below are my configure, is there anything missing for res...

I have a EVB NUCLEO-H503RB and tried to implement I3C Target feature. Before testing on I3C system, I would like to test some basic read write with legacy I2C Controller. However, I just found that it seems to be not support with static address on I3...

Yes, I have both I3C Controller and Target on the same board.I3C1 act as Target with Interrupt.I3C2 act as Controller with polling (no Interrupt).

Hi @Foued_KH ,I've already setup with "I3C_TXFIFO_THRESHOLD_1_4".The interrupt condition is "One or more free space available in TX-FIFO". (1 byte empty then trigger Interrupt)Is it possible to change the interrupt condition to "TX-FIFO empty" ? (onl...

Hi @Foued_KH ,I think the root cause may be the Target Interrupt "I3C_EVR_TXFNFF" trigger when TX-FIFO is not full with 8 bytes.Is it required to fill TX-FIFO full every time before I3C Target being read from Controller?Are we able to implement I3C T...

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:Why is it happening?Is there any way to fix ...
