    I am noticing 1117M3 is getting hot quickly. Do I have right component here?

    Maybe you switched them? 1.2V close to FPGA. Check voltages.
    Check 16MHz generator.

    Output Type: Adjustable.

    Hmmmm, if i'm not mistaken they should output 1.25V, that's good news.
    Which one heats up? 3.3V rail or 1.2V rail?
    Can you messure voltages?

    Desolder the 3.3V 1117 and check (pcb) if 3.3V is shorted to gnd.
    Measure 1.2V.

    I am not sure if this is normal?

    No.
    Desolder 16MHz generator (i'm guessing) and check again.

    What exactly happened?
    Can you make a video (with led's visible)? Start from power on.

    I write image with command:
    Quote:
    cp SD_clean.raw /dev/sdX

    without number at the end.
    (Be careful)

    Are you sure your card is "/dev/disk3"?

    What "dmesg" shows when you insert your card.

    If the card works for uploadning cores, it should work with amiga.
    There must be something wrong with writing the image.
    Partitions should be visible in workbench.
