To build Embedian’s SMARC-FiMX7 u-boot and linux kernel, you will need to install the following Linaro arm compiler first:

For u-boot 2018.03 and Linux 4.14.98, you need to use the following newer Linaro arm compilier.

Note1:

If the board is SMARC-FiMX7-S (Solo Core), use
$ make ARCH=arm CROSS_COMPILE=${CC} smarcfimx7s_ser3_defconfig

If the board is SMARC-FiMX7-D-2G (Dual Core with 2GB DDR3L), use
$ make ARCH=arm CROSS_COMPILE=${CC} smarcfimx7d_2g_ser3_defconfig

Note 2:

"ser3" stands for console debug port. In this example, we uses SER3 as debug port. If user uses SER0 as your debug port, make change to "ser0" instead. Same as SER1 and SER2.

Note 3:

The SMARC-FiMX7 module always boot up from the on-module SPI NOR flash. The factory default will be u-boot.imx pre-installed with SER3 as console output. In some cases when the SPI NOR flash is empty or needs to be upgraded. Users can shunt crossed the TEST# to ground. In this way, the SMARC-FiMX7 module will boot up to carrier SD card, if TEST# pin is shunt crossed. The u-boot.imx image are the same, the difference is how you flash u-boot.imx. This will be explained in the "Setup SD card" section.

After compiled u-boot, it will generated u-boot.imx (u-boot-dtb.imx if using u-boot v2017.03) ) and u-boot.bin. The only difference is IVT header that will tell i.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-FiMX7 will boot up to SD card first. The command to copy u-boot.imx (rename u-boot-dtb.imx to u-boot.imx if using v2017.03) 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.
MAC address is factory pre-installed at on board I2C EEPROM at offset 60 bytes and 66 bytes (ENET2). It starts with Embedian's vendor code 10:0D:32. u-boot will read it and pass this parameter to kernel.
If your rootfs is yocto built, the kernel modules will be included in the rootfs.
