It should boot from the media selected by the switch. However, uboot typically instructs it to load the kernel from a specific volume by UUID. When more than one volume has the same UUID, it picks the first one it finds (eMMC).
The simplest solution is to change the UUID on either the SD card or eMMC along with the boot.ini on the same media.https://github.com/mdrjr/5422_bootini/b ... ot.ini#L13
Note that future updates may overwrite boot.ini requiring the change to made again.
