I'm trying to boot from the micro sd card, but it boots from the eMMC indepentent upon the position of the maskrom jumper.

Is this because there is not boot.env file as indicated?
Where is u-boot located? Is it starting at the first sector of the eMMC?
The currently installed u-boot appears to look for /boot/boot.env on the first parition?
