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)

$ sudo dd if=u-boot.imx of=${DISK} bs=512 seek=2 
Note
  1. If your u-boot hasn't been finalized and still under development, it is recommended to shunt cross the test pin and boot directly from SD card first. Once your u-boot is fully tested and finalized, you can fuse your u-boot to SPI NOR flash.
  2. When TEST# pin of SMARC-FiMX6 FiMX7 is not shunt crossed, it will always boot up from SPI NOR flash. U-boot will read the BOOT_SEL configuration and determine where it should load zImage and device tree blob. When TEST# is shunt crossed (pull low), it will always boot up from SD card.

Copy Kernel Modules:

...

Note
titleNote
  1. After compiled u-boot, it will generated u-boot.imx (u-boot-dtb.imx if using and u-boot v2017.03) and u-boot-dtb.bin. The only difference is IVT header that will tell i.MX6 MX7 internal ROM where to load u-boot. If the firmware in SPI flash need to be update or empty. Users could pull the TEST# pin on carrier board to low. In this way, SMARC-FiMX6 FiMX7 will boot up to SD card first. The u-boot we need to use now will be u-boot-dtb.imx. Please rename it as u-boot.imx. The command to copy u-boot.imx to SD card now is:
    $ sudo dd if=u-boot.imx of=${DISK} bs=512 seek=2 
    In this case, user will only need to copy uEnv.txt, zImage and device tree blob to partition one of your boot device.  
  2. MAC address is factory pre-installed at on board I2C EEPROM at offset 60 bytes. It starts with Embedian's vendor code 10:0D:32. u-boot will read it and pass this parameter to kernel.
  3. If your rootfs is yocto built, the kernel modules will be included in the rootfs.

...

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.
