8 CHAPTER 1 Introduction 1.1 About this manual The purpose of this document is to describe the functions and abilities of the emfile NAND Image Creator.

1.2 What is the purpose of the NAND Image Creator? The NAND Image Creator is a command line tool which gives the customer the ability to build a file containing 1-to-1 representation of NAND flash device (image) with preselected files and directories found on the host PC. 1.2.1 How is the image created? Files and directories from the host PC are copied to the image file using emfile API function creating the file structure which is required on the target device. 1.2.2 How is the NAND flash image transferred to the target? The image file created by the NAND Image Creator is a standard bin file which can be flashed directly into the NAND flash of the target via third party tools. 9 UM02002 User & Reference Guide of NAND Image Creator

16 CHAPTER 2 The NAND Image Creator 2.3 Flash image related functions The following section describes functions required to create a NAND flash image. 2014-2013 SEGGER Microcontroller GmbH & Co. KG

17 2.3.1 createimage Creates/opens a new/existing NAND flash image file on the host PC. createimage <ImageFileName> <NumBlocks> <PagesPerBlock> <PageSize> [<SpareAreaSize>] ImageFileName Filename of the NAND flash image file that will be created/ opened. NumBlocks Number of blocks in the NAND flash device PagesPerBlock Number of pages in a NAND block (Typ. 64) PageSize Number of user bytes which can be saved in a page (Typ. 2048 bytes, must be a power of 2 value) Optional number of add. bytes in a page reserved for management SpareAreaSize information. When not specified the value is computed as 1/32 of PageSize Table 2.2: createimage parameter list Additional information The size of the image file will be NumBlocks * PagesPerBlock * (PageSize + SpareAreaSize) bytes large. If the image file already exists but the size of the file does not match it will be silently overwritten. The example shows how to create 128MByte image file. createimage C:\nand.bin 1024 64 2048

18 CHAPTER 2 The NAND Image Creator 2.3.2 setdrivertype Configures the type of NAND driver which will be used to access the NAND flash on the target. setdrivertype <DriverType> Additional information This command is optional. If not executed an image is created which can be accessed using the Universal NAND driver. The examples shows how to specify that the SLC1 NAND driver is used on the target to access the NAND flash. setdrivertype slc1 The type of NAND driver used to access the files on the target. DriverType "slc1" - SLC1 NAND driver (FS_NAND_Driver) "uni" - Universal NAND driver (FS_NAND_UNI_Driver) Table 2.3: setdrivertype parameter list 2014-2013 SEGGER Microcontroller GmbH & Co. KG

19 2.3.3 setsectorsize Configures the error correction type. setsectorsize <SectorSize> Additional information This command is optional. It can be used to set the size of the logical sector when the SLC1 NAND driver type is selected. Any power of 2 value between 512 bytes and the number of bytes in a NAND page size can be used. When this command is not executed the size of the logical sector is set automatically to the configured page size of NAND flash image. This example shows how to set the logical sector size to 512 bytes. setsectorsize 512 Number of bytes in a logical sector (Typ. 2048 bytes, must be SectorSize a power of 2 value) Table 2.4: setsectorsize parameter list

20 CHAPTER 2 The NAND Image Creator 2.3.4 addpartition Configures a new logical partition. addpartition <SectorStart> <NumSectors> [<PartType>] Index of the first sector in the partition relative to the beginning of the storage device. StartSector NumSectors Number of sectors in the partition. Type of the partition to create. Permitted values are: "normal" - The entire partition space can be used by the file system as storage (default). PartType "raid1" - The file system can use only half of the partition space as storage. The other half is used as mirror. Table 2.5: addpartition parameter list Additional information This command is optional. It allows the creation of logical partitions on the image. The command fails if the defined sector range overlaps the range of an already defined logical partition. A maximum of four logical partitions can be created. The partition list has to be stored to image after initialization of the image using the creatembr command. The data on the created logical partitions can be accessed using the DISKPART logical driver. For more details refer to UM02001 emfile User and Reference Guide available from here: https://www.segger.com/downloads/emfile. The logical partitions can be formatted using the format command. This example shows how to configure 2 logical partitions. The sector 0 is reserved for Master Boot Record where the partition list is stored. addpartition 1 10000 addpartition 10001 20000 A possible emfile configuration that allows the application to access the logical partitions looks like this: 2014-2013 SEGGER Microcontroller GmbH & Co.
