# csf\_parser(1)

Parse signed images or CSF binary files for NXP secure boot

## NAME

csf\_parser - Parse signed images or CSF binary files for NXP secure boot

## SYNOPSIS

**csf\_parser** **\[-d\]** (**-s** *signed\_image* \| **-c** *csf\_binary*)

## DESCRIPTION

**csf\_parser** is a utility to parse signed images or binary Command Sequence Files (CSF) used in the secure boot process on NXP i.MX processors. It extracts and displays information from either a signed boot image or a CSF binary file.

Only one input type (signed image or CSF binary) can be processed at a time.

## OPTIONS

- **-d**, **--enable-debug**

  Enable debug information output.

- **-s**, **--signed-image** *file*

  A signed image file as input for parsing.

- **-c**, **--csf-binary** *file*

  A CSF binary file as input for parsing.

## EXAMPLES

- Parse a signed image with debug enabled:

  ```
    csf_parser -d -s signed_image.bin
  ```

- Parse a CSF binary file:

  ```
    csf_parser -c csf_binary.bin
  ```
