TS-7970 uboot

From embeddedTS Manuals

This platform uses U-Boot as the bootloader to launch the full operating system. The i.MX6 processor loads U-Boot from the on-board 8 MiB SPI flash. U-Boot provides support for loading data from various mediums; this allows booting a kernel from SD, eMMC, SATA, NFS, or USB. U-Boot is a general purpose bootloader that is capable of booting into common Linux distributions, Android, Windows, or custom software OSes.

On a normal boot the output should be similar to the output below:

U-Boot 2014.10-gee73348 (Oct 07 2015 - 11:12:20)

I2C:   ready
DRAM:  1 GiB
SF: Detected N25Q64 with page size 256 Bytes, erase size 4 KiB, total 8 MiB
In:    serial
Out:   serial
Err:   serial
Net:   using phy at 7

By default the device will boot to SD or eMMC depending on the status of the "SD Boot" jumper on startup.

To break into the U-Boot console, press and hold the SW1 button while the unit is being powered up. This mode will also check for a USB mass storage device to use for production purposes.
