GP2040-CE Binary Tools
Tools for working with GP2040-CE binary dumps.
Dependencies
Interacting with your board (e.g. getting dumps, etc.) requires picotool, and currently the expectation is that you can run it yourself before invoking these tools. That may change one day.
Installation
% pip install gp2040ce-binary-tools
Development Installation
% git clone [URL to this repository]
% cd gp2040ce-binary-tools
% python -m venv venv
% source ./venv/bin/activate
% pip install -e .
% pip install -Ur requirements/requirements-dev.txt
Tools
In all cases, online help can be retrieved by providing the -h
or --help
flags to the below programs.
Config Editor
A terminal UI config editor, capable of viewing and editing existing configurations, can be launched via
edit-config
. It supports navigation both via the keyboard or the mouse, and can view and edit either a binary file
made via picotool
or configuration directly on the board in BOOTSEL mode over USB.
Simple usage:
Key(s) | Action |
---|---|
Up, Down | Move up and down the config tree |
Left, Right | Scroll the tree left and right (when content is long) |
Space | Expand a tree node to show its children |
Enter | Expand a tree node, or edit a leaf node (bools toggle) |
Tab (in edit popup) | Cycle highlight between input field and buttons |
Enter (in edit popup) | Choose dropdown option or activate button |
S | Save the config to the opened file |
Q | Quit without saving |
A quick demonstration of the editor is available on asciinema.org.
concatenate
concatenate
combines a GP2040-CE firmware .bin file (such as from a fresh build) and a GP2040-CE board's storage
section .bin or config (with footer) .bin, and produces a properly-offset .bin file suitable for flashing to a board.
This may be useful to ensure the board is flashed with a particular configuration, for instances such as producing a
binary to flash many boards with a particular configuration (specific customizations, etc.), or keeping documented
backups of what you're testing with during development.
The produced binary can be written to a file with --new-binary-filename FILENAME
or straight to a RP2040 in BOOTSEL
mode with --usb
.
Sample usage:
% concatenate build/GP2040-CE_foo_bar.bin storage-dump.bin --new-binary-filename new-firmware-with-config.bin
dump-config
dump-config
replaces the need for picotool in order to make a copy of the GP2040-CE configuration as a binary file.
This could be used with the other tools, or just to keep a backup.
Sample usage:
% dump-config -P ~/proj/GP2040-CE/proto -P ~/proj/GP2040-CE/lib/nanopb/generator/proto `date +%Y%m%d`-config-backup.bin
dump-gp2040ce
dump-gp2040ce
replaces the need for picotool in order to make a copy of a board's full GP2040-CE image as a binary file.
This could be used with the other tools, or just to keep a backup.
Sample usage:
% dump-gp2040ce `date +%Y%m%d`-backup.bin
visualize-storage
visualize-storage
reads a GP2040-CE board's configuration, either over USB or from a dump of the board's flash
storage section, and prints it out for visual inspection or diffing with other tools. It can also find the storage
section from a GP2040-CE whole board dump, if you have that instead. Usage is simple; just connect your board in BOOTSEL
mode or pass the tool your binary file to analyze along with the path to the Protobuf files.
Because Protobuf relies on .proto files to convey the serialized structure, you must supply them from the main GP2040-CE project, e.g. pointing this tool at your clone of the core project. Something like this would suffice for a working invocation (note: you do not need to compile the files yourself):
% visualize-storage -P ~/proj/GP2040-CE/proto -P ~/proj/GP2040-CE/lib/nanopb/generator/proto --filename memory.bin
(In the future we will look into publishing complete packages that include the compiled _pb2.py
files, so that you
don't need to provide them yourself.)
Sample output:
% visualize-storage -P ~/proj/GP2040-CE/proto -P ~/proj/GP2040-CE/lib/nanopb/generator/proto --usb

Miscellaneous
Dumping the GP2040-CE board with picotool
Some of these tools require a dump of your GP2040-CE board, either the storage section or the whole board, depending on
the context. The storage section of a GP2040-CE board is a reserved 8 KB starting at 0x101FE000
. To dump your board's
storage with picotool:
% picotool save -r 101FE000 10200000 memory.bin
And to dump your whole board:
% picotool save -a whole-board.bin
