  • RE: FPC402: SCL stuck for more than 300ms issue after hot-plug of SFP56

    Hi again, Strange thing is here: FPC only need 20ms after power on. But our SW wait for 300ms after power on. This means SCL stuck happened and continue to 700ms and then recovered. So if you are suggesting we add a FPC402 reset(not port) after…

  • AM625: I2C controller becomes stuck with SCL low

    Part Number: AM625 On our TQMa62xx SoM, we've observed the I2C controller becoming stuck under high system load (simultaneous stress test of CPU, RAM and various peripherals). We've noticed multiple symptoms of this state: SCL is permanently pulled…

  • RE: FPC402: Port state machine is stuck when host side SCL is interrupted or delayed for long time during remote downstream port access.

    Resolved
    Hi Liming, Glad you were able to mitigate the issue. Unfortunately, there are not any additional hidden registers that could help indicate this status. You could check the "Port SCL Stuck Interrupt Register" and "Port SDA Stuck Interrupt Register…

  • MSPM0G3507: How to know and then reset if I2C SCL is held low abnormally

    Resolved
    Part Number: MSPM0G3507 Tool/software: Hi champs, I am asking this for our customer. The user uses I2C as target mode to implement PMBus 1.2. When the I2C SCL is held low abnormally, how does the user know and then reset I2C module? For example…

  • MSP430FR5738: I2C slave sometimes holds scl low until bus is restarted

    Part Number: MSP430FR5738 Hi, We are having an issue where sometimes the msp stops replying correctly on the i2c until it gets reset. The msp acts as slave. When it starts to misbehave, the msp acknowledges the address, the data received, but…

  • RE: TMP468: THERM2 output stuck low until power-cycle

    Hello Carl, If the 3V3_i power is always on, then then the temperature should be constantly on and can constantly receive THERM Status. There is not a setting that would cause the THERM2 output to get stuck low. I do not see an issue with turning off…
