NAME

       bct_dump — tegra boot config table (bct) dumping utility

SYNOPSIS

       bct_dump [bct filename to read and display]

DESCRIPTION

       This manual page documents briefly the bct_dump command.

       bct_dump is used to convert the contents of a boot config table (BCT) used in NVIDIA Tegra devices, ready
       to be further proceeded by cbootimage (1).  The BCT is usually placed in the first bytes of  the  storage
       device and can be extracted using tegrarcm(1).

       The  BCT is a data structure that provides basic initialization parameters, and defines the bootloader to
       execute.

       The BCT contains:

          •  Header information, such as cryptographic validation hashes and size information.

          •  Boot memory configuration. This allows the boot memory controller to be  programmed  optimally,  in
             order to read the bootloader.

          •  SDRAM  controller  configuration.  This  allows  the  SDRAM  controller to be programmed, and hence
             external SDRAM accessed.

          •  A bad block table.

          •  Information about the bootloader to execute.

          •  A "customer data" area, which may be used to store arbitrary customer- or  device-software-specific
             data. This area includes the ODMDATA.

OPTIONS
