below is the consle log:
fl::target -lc "LC for Simple Flash (1)"
fl::target -b 0x0 0x40000
fl::target -v off -l off
cmdwin::fl::device -d "S29GL128P" -o "8Mx16x1" -a 0xff000000 0xffffffff
cmdwin::fl::image -f "E:\\BinHong\\Projects\\HDBUS\\doc\\P2020\\ltib-p1020rdb_p2020rdb-20101029\\rootfs\\boot\\u-boot.bin" -t "Auto Detect" -re on -r 0xff000000 0xffffffff -oe off
