This platform includes U-Boot as the bootloader to load and boot the full operating system. The i.MX6UL processor loads U-Boot from the eMMC flash at power-on. U-Boot allows booting images from the microSD, eMMC, NFS, or USB. U-Boot is a general purpose bootloader that is capable of booting into common Linux distributions, Android, QNX, or others.
On a normal boot, output from U-Boot will be similar to the following:
U-Boot 2016.03-00305-g75344a5 (Dec 15 2017 - 13:53:14 -0800) CPU: Freescale i.MX6UL rev1.1 at 396 MHz Reset cause: WDOG Board: Technologic Systems TS-7553-V2 I2C: ready DRAM: 512 MiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 Net: FEC0 [PRIME] Booting from the SD card ... ** File not found /boot/boot.ub ** 34511 bytes read in 162 ms (208 KiB/s) 5460520 bytes read in 391 ms (13.3 MiB/s) NO CHRG jumper is set, not waiting Kernel image @ 0x80800000 [ 0x000000 - 0x535228 ] ## Flattened Device Tree blob at 83000000 Booting using the fdt blob at 0x83000000 Using Device Tree in place at 83000000, end 8300b6ce Starting kernel ...
By default the board will boot to SD or eMMC depending on the status of the "SD Boot" jumper on startup.
