To build Embedian’s SMARC-FiMX6 u-boot and linux kernel, you will need to install the following Linaro arm compiler that is the same as that we build for SMARC-T335X:

For For u-boot 20142018.04, 03 and Linux 34.14.98, you need to use the following newer Linaro arm compilier.

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.MX6 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 will boot up to SD card first. The u-boot we need to use now will be 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.
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.
If your rootfs is yocto built, the kernel modules will be included in the rootfs.
