Is the file on external medium (usb stick, SD card)? the boards are custom?
Try to debug, sometimes it helps.

the file is on external flash w25q128jv and the board are custom.
debug many time, but no use.

If the boards are custom, there is a chance that some boards are defective. Can you get more boards to test ?
