When the NAND flash is not burned yet, the product is usually configured in order to boot from a different device such as an SD card or through serial download mode. The burning of the boot partition is performed by the kobs-ng tool. Instruction ha to be modified according to Standalone boot from NAND page. This application note was validated before XELK 4 kit version which is using u-boot SPL.

The following section will describe how to burn the boot partition in practice.

The second (redundant) copy of the firmware to loadДЇor more details about the bootrom e the NAND boot process, please refer to the System Boot chapter of the Reference Manual of the specific i.MX6 Application Processor.The Discovered Bad Block Table (DBBT) which is the data structure used to manage the bad blocks of the NAND flash.Three addresses which indicate where are located.A data structure called NAND Control Block (NCB).A 1MB area (named Flash Control Block, FCB) which, in turn, includes.In case the NAND memory is the boot devices, this implies that the boot partition must be organized in order fulfill the bootrom requirements. The bootrom plays a major role in the boot process of any i.MX6 SoC. The following image shows the organization of the boot partition. From the point of view of MTD partitions, the boot partition is mtd0 which is 8MB.Д«oot partition organization The boot firmware image is the U-Boot binary file ( mењ†sx_board_nand_u-boot.imx). The test bed used in this example consists of an i.MX6SoloX-board equipped with a 512MB 8-bit asynchronous 1-bit ECC SLC NAND memory which is connected to the EIM bus of the SoC. This document provides information about the NAND device management, in order to handle it properly when it is used as the boot device on NXP i.MX6-based products.Д®ven though the example shown here refers to an i.MX6SoloX board, the approach is substantially the same across all the i.MX6 family. Several techniques such as wear leveling and bad block management have to be implemented to achieve an acceptable reliability. This is especially true when the NAND flash is used as the boot device. With respect to the NOR flash memories, NAND devices are known to be quite challenging with regard to the reliability.
