The uploaded contents from the ICDI USB port through USB DFU is 8+256000 bytes. With the 8 bytes at the head "01 00 06 00 00 e8 03 00". It is a DFU_CMD_PROG record, according to "Stellaris® Application Update Using the USB DFU Class". So this image is starting from block 6 and extends to the end (256KiB).
Using the lmtool on Windows, I got the image 256KiB.
But the contents disagree, as I compared the 256KiB image from 6k with the 8+256000 bytes image from 8.
It seems the contents I got using ICDI USB DFU interface is not correct! Why?
