Setup SD Card
...
For these instruction, we are assuming: DISK=/dev/mmcblk0, "lsblk" is very useful for determining the device id.
...
The u-boot.imx is pre-installed in SPI NOR flash at factory default. SMARC-FiMX6 FiMX7 is designed to always boot up from SPI NOR flash and to load zImage, device tree blob and root file systems based on the setting of BOOT_SEL. If users need to fuse their own u-boot or perform u-boot upgrade. This section will instruct you how to do that.

If SPI NOR Flash is empty
In some cases, when SPI NOR flash is erased or the u-boot is under development, we need a way to boot from SD card first. Users need to shunt cross the TEST# pin to ground. In this way, SMARC-FiMX6FiMX7 will always boot up from SD card.
Copy u-boot.imx to the boot partition. (Note: Rename u-boot-dtb.img to u-boot.img if your for u-boot is v2017v2022.0304)

Setting up eMMC usually is the last step at development stage after the development work is done at your SD card or NFS environments. From software point of view, eMMC is nothing but a non-removable SD card on board. For SMARC-FiMX6FiMX7, the SD card is always emulated as /dev/mmcblk1 mmcblk0 and on-module eMMC is always emulated as /dev/mmcblk3mmcblk2. Setting up eMMC now is nothing but changing the device descriptor.
