Partition Hex Example

This directory contains example files showing how to use the Partition Hex module.

Files

  • generate_hex.py: A Python script that demonstrates how to generate an Intel HEX file from JSON data
  • sample_data.json: An example JSON file containing sample provisioning data

Usage

To use this example, you would typically:

  1. Define a partition in your application's partition manager configuration
  2. Configure the Partition Hex module in your application's prj.conf or sysbuild.conf
  3. Run your build, which will invoke the script to generate the hex file

Example Command Line

# Manual execution example (normally called by CMake)
python generate_hex.py \
  --address 0x80000 \
  --output provision_data.hex \
  --max-size 4096 \
  --json-file sample_data.json \
  --magic 0x57FA57FA \
  --prepend-length

Example Configuration

CONFIG_PARTITION_HEX=y
CONFIG_PARTITION_HEX_PARTITIONS="app_provision"
CONFIG_PARTITION_HEX_COMMANDS="\${PYTHON_EXECUTABLE} \${APP_DIR}/modules/partition_hex/example/generate_hex.py --json-file \${APPLICATION_CONFIG_DIR}/provisioning_data.json --magic 0x57FA57FA --prepend-length"
CONFIG_PARTITION_HEX_DEPENDENCIES="\${APPLICATION_CONFIG_DIR}/provisioning_data.json"

Requirements

  • Python 3.6 or later
  • IntelHex Python package (pip install intelhex)
