Hi,
I am trying to use DFU to flash the SPI NOR on a mx6qsabresd. These are the changes I made:

Then I run: => dfu 0 sf 0:0:25000000:0 SF: Detected M25P32 with page size 256 Bytes, erase size 64 KiB, total 4 MiB
and on the PC host: sudo dfu-util -D u-boot.imx -a u-boot dfu-util 0.8

and the mx6qsabresd hangs at the download mark: ########
I used the dfu_alt_info from Boundary Devices' U-boot.
I am able to flash the SD card (need to adjust dfu_alt_info in this case), so DFU is working.
Is there anything I am missing to get SPI NOR to be flashed via DFU?
Thanks,
