Does USB Blaster supports AS X4 mode ? - Does USB Blaster supports AS X4 mode ? Dear, Does USB blaster support AS X4 mode ? It seems that it only supports AS X1 mode. How can I download .pof into EPCQ-L in AS X4 mode when using USB Blaster? Except the J-TAG -> SFL -> EPCQ-L path. Thank you. Brs, Leon Replies: Re: Does USB Blaster supports AS X4 mode ?
