when uplaoding a file, at least from a nand partition, the complete mtd nand partition size is transferred. This leads in a wrong md5sum as the filesize is different between the downloaded file and the uploaded file. Limit the uploaded filesize to the downloaded fixes this.

Tested this on the siemens boards, with current ml I get:
Init script for generating data necessary for DFU test script OK ========================================================================================= DFU EP0 transmission test program Trouble shoot -> disable DBG (even the KERN_DEBUG) in the UDC driver @ -> TRATS2 # dfu 0 mmc 0 ========================================================================================= File: dat_960.img TX: md5sum:2947e8f573bc34ba3791f991bd2da869 RX: md5sum:cde0b2024d8ddb55eee9d4b51264ad67 -------> FAILED
with this patch:
