     hi,I want to write bootloader example of MQX 4.0.2 for VYBRID to SD card with SD card driver or MFS.I want to know the working pricinple of "ddcopy.exe" (install path\Freescale_MQX_4_0\tools\ddcopy ).I know there is a file "",but I know few about the python.The example in the file "" as :

                  infile=<file_path>    input image file

                  outdevice=<volume:>   output volume, eg. f:

                  seek=<offset>         volume device offset

             Example: ddcopy.exe infile=bootloader_vybrid_twrvf65gs10_a5.imx outdevice=<your disk name:> seek=0x400

     I want to thr "seek" means  offset the  SD card  or  the partition of SD card(for example H:),I also want to know the unit about "seek":byte or sector?
