This article is specific to Nvidia Tegra modules. For information about the PXA module flash layout, see PXA Flash Layout. The flash layout is created in recovery mode with the NvFlash tool. The configuration is defined in the file ending with .CFG that is provided with our OS images. A set of parameters is defined for each partition. Here is an example:

[partition]
name=BCT
id=2
type=boot_config_table
allocation_policy=sequential
filesystem_type=basic
size=3145728
file_system_attribute=0
partition_attribute=0
allocation_attribute=8
percent_reserved=0

In most cases you do not need to change the flash layout. In cases you need to change the size of a partition, you can change the size parameter (size in bytes).

An overview of the partitions is provided below.
