Boot from SD card & eMMC

My thought/expectation is like if i
a.Press the boot button and power on, BBB has to boot from SD card.
b.Don’t press the boot button and power on, BBB has to boot from eMMC.

By default “u-boot” on the eMMC will scan the microSD for a bootable image (it looks for /uEnv.txt and /boot/uEnv.txt trigger files and if u-boot finds them it’ll boot it)…
