    Boot from i2c sometimes default to USB boot

    LuCu_4098176

      Hello,

       

      Sometimes after a manual hard reset (without powering off everything) the boot defaults to USB and the code stored in the eeprom is no longer read.

      I did my research an found that for some unknown reason SDA gets low and then the FX3 assumes the i2c bus is in use and default to USB boot.

      After that no matter what I do it will stay like this forever and I need to take power off and turn it all back on.

       

      When powering it up all works perfect all the times. It is only if I apply a manual hardware reset with the chip powered that sometimes it locks up in this state.

       

      Is there a way to avoid this situation ?

       

       

      Thanks.
