The imx_bootlets package in LTIB contains the code that will be the first code loaded and executed by ROM when booting a build of the Linux BSP. It is responsible for initializing some of the low level peripherals such as the integrated power supply and the DRAM controller as well as a few other initialization tasks.

 

The default configuration of the bootlet code for the latest i.MX233 and i.MX28x release (SDK 10.05 and SDK 10.12 respectively) support a hardware configuration that has both a LiIon battery configuration (as shown in the reference schematics for these platforms as shown on freescale.com). For other configurations though such as a VDD5V connection only or a DCDC_BATT/Battery connection only, some additional changes are recommended.
