The boot ROM of NXP systems on a chip (SOCs) support configuring the peripherals through specific pins of the system on a chip. On the i.MX6 family it also supports configuring the boot order through efuses. The boot ROM of several NXP SoCs have many ways to load the first stage bootloader (from eMMC, microSD, USB, etc.).
The first stage bootloader, which is a part of the MBR, is a 512-byte image containing the vendor-specific program code and a partition table. [6] As mentioned earlier in the introduction part, the first stage bootloader will find and load the second stage bootloader. [6] It does this by searching in the partition table for an active partition. [6]
A bootloader, also spelled as boot loader [1] [2] or called bootstrap loader, is a computer program that is responsible for booting a computer and booting an operating system. If it also provides an interactive menu with multiple boot choices then it's often called a boot manager .
The boot partition (or boot volume) [5] is the disk partition that contains the operating system folder, known as the system root or %systemroot% in Windows NT. [6]: 174 Before Windows 7, the system and boot partitions were, by default, the same and were given the "C:" drive letter.

Unlocking the bootloader allows installing and running unsigned code on a device, including user customized software. Operating outside the manufacturer specification might usually result in voiding any warranties and may make the device susceptible to data theft, as the integrity of the operating system (as intended by the manufacturer) can no longer be guaranteed. [1]
The MBR bootstrap code loads and runs (a boot loader- or operating system-dependent) volume boot record code that is located at the beginning of the "active" partition. The volume boot record will fit within a 512-byte sector, but it is safe for the MBR code to load additional sectors to accommodate boot loaders longer than one sector, provided ...
flashing lock/oem lock *** – locks an OEM unlocked bootloader. erase – erases a specific partition. reboot – reboots the device into either the main operating system, the system recovery partition or back into its boot loader. devices – displays a list of all devices (with the serial number) connected to the host computer.
