| Supported Targets | ESP32 | ESP32-C2 | ESP32-C3 | ESP32-C5 | ESP32-C6 | ESP32-H2 | ESP32-P4 | ESP32-S2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | -------- | -------- | -------- | -------- | -------- | # Partitions Tool Example This example demonstrates common operations the partitions tool [parttool.py](../../../components/partition_table/parttool.py) allows the user to perform: - reading, writing and erasing partitions, - retrieving info on a certain partition, - dumping the entire partition table Users taking a look at this example should focus on the contents of the Python script [parttool_example.py](parttool_example.py) or shell script [parttool_example.sh](parttool_example.sh). The scripts contain programmatic invocation of the tool's functions via the Python API and command-line interface, respectively. Note that on Windows, the shell script example requires a POSIX-compatible environment via MSYS2/Git Bash/WSL etc. The example performs the operations mentioned above in a straightforward manner: it performs writes to partitions and then verifies correct content by reading it back. For partitions, contents are compared to the originally written file. For the partition table, contents are verified against the partition table CSV file. An erased partition's contents is compared to a generated blank file. ## How to use example ### Build and Flash Before running either of the example scripts, it is necessary to build and flash the firmware using the usual means: ```bash idf.py build flash ``` ### Running [parttool_example.py](parttool_example.py) The example can be executed by running the script [parttool_example.py](parttool_example.py) or [parttool_example.sh](parttool_example.sh). Python script: ```bash python parttool_example.py ``` Shell script: ``` ./parttool_example.sh ``` The script searches for valid target devices connected to the host and performs the operations on the first one it finds. To perform the operations on a specific device, specify the port it is attached to during script invocation: Python script: ```bash python parttool_example.py --port /dev/ttyUSB2 ``` Shell script: ``` ./parttool_example.sh /dev/ttyUSB2 ``` ## Example output Running the script produces the following output: ``` Checking if device app binary matches built binary Found data partition at offset 0x110000 with size 0x10000 Writing to data partition Reading data partition Erasing data partition Reading data partition Partition tool operations performed successfully! ```
