Freescale ATK (advanced toolkit) is an embedded system flash burning software designed for its MX series CPU core. It can be used to burn Bootloader and kernel to flash.
(Nor, Nand, MC/SD ...).
The principle and workflow are as follows:
First, set the jumper to UART/USB boot. Then, after the Board is powered on, the ROM in the SOC starts to initialize the internal RAM and waits for data on the UART/USB
And load it to internal RAM.
Then on the host side, after starting the GUI, select the flash operation to be executed and other related options. After selecting the option, click execute. the execution process is divided into two phases:
1. Ram kernel and flash lib are first stationed in the SOC internal RAM through UART/USB (SOC has been initialized );
2. Host DLL generates commands Based on the ram kernel protocol, and sends flash operation commands to SOC through UART or USB.

In the SOC, the RAM kernel in internal RAM receives the flash operation command from the host and calls the flash operation implementation in Flash lib to control NFC
(NAND Flash Controller) to complete the corresponding flash operations. The Flash lib operation result is returned to the ram kernel and sent to the host, which is displayed on the GUI.
