    Hello Tseong,

    Does your picozed 7020 SOM+FMC Carrier v1 power up properly when you have nothing plugged into CON1?(pg module led on)

    If the pg module led does not light up when power on your board with no FMC Module attached, then you most likely have damaged some different aspect of your board due to the device not going into overcurrent protection before somthing was damaged. 

    To answer your question "Will the board survive by replacing the inductor?"

    If you are unable to power up the board with the FMC disconnected, there is a chance somthing is shorted/damaged on the 3.3V rail. Inductors don't typically get "damaged" so if it won't power up without that FMC load, then you most likely have a different issue.

    Hello Josh.

    --> Pg module is not on. And the test proceeded to the oscilloscope course with nothing connected to con1.

     

    To answer your question "Will the board survive by replacing the inductor?"

    -->The inductor replacement did not proceed because there was no replacement part. Sorry.

    Can you guess the problem with your thoughts?

     

    I'm sorry I asked a lot. Thank you very much.
