If won't pass value to dfu->r_left, it always 0, make no transfer, the dfu-util on host side report failed. So, before starting transfer, pass the value, then nand uploading can work.

Please do not add nand related code to "generic" DFU code. This can damage DFU operation with other memories (like eMMC).
Such code shall be added to dfu_nand.c file.
ret = dfu->read_medium(dfu, 0, dfu->i_buf_start,&dfu->r_left); if (ret != 0) { debug("%s: failed to get r_left\n", __func__);
