Let's say we are not using DFU and we want to flash u-boot.imx in the
SD card of mx6qsabresd, for example. In this case, we simply do:

dd if=u-boot.imx of=/dev/mmcblk0 bs=1k seek=1

and the new u-boot.imx is flashed in the SD card, and the env vars are
not touched.

Same happens with DFU, so that's why I include the ' env default -f
-a' in the instructions.

Not sure if I understand the issue you are trying to describe.
