    This is what my U2 does.

    These are the settings I have for the PK4:
    Code:
    -TPPK4 -P$target-device$ -F$hex-filename$ -E -M -OAS2 -OB -OL -OV -W -YP -YE
    E = Erase Flash Device (there are no options)
    M = Program entire device (does not include calibration, same like U2)
    OAS2 = Maximum programming speed
    OB = Batch mode operation (so the window stays open to check out the results)
    OL = Release from RESET NOT SURE ABOUT THIS GUY!
    OV = Verify device ID before program in batch mode
    W = Power target from tool
    YE = Verify EEPROM
    YP = Verify Program memory (U2 verifies Code, Calibration, Data, User ID and Configuration)

    If anything, the U2 should be waaaaay slower, it verifies more, and the PK4 is supposed to be running at max speed and it's plugged in a SS USB port.

    Weird...
