utils

A collection of scripts and simple applications

• dtapply - A script that reads a Raspberry Pi config.txt and uses dtmerge to apply all its dtparam and dtoverlay directives to a base .dtb file.
• dtmerge - A tool for applying compiled DT overlays (*.dtbo) to base Device Tree files (*.dtb). Also includes the dtoverlay and dtparam utilities.
• eeptools - Tools for creating and managing EEPROMs for HAT+ and HAT board.
• kdtc - A tool for compiling overlays with #includes, etc., as used in the kernel tree.
• otamaker - A tool for building Remote Update artefacts, as used by Raspberry Pi Connect Remote Update.
• otpset - A short script to help with reading and setting the customer OTP bits.
• overlaycheck - A tool for validating the overlay files and README in a kernel source tree.
• ovmerge - A tool for merging DT overlay source files (*-overlay.dts), flattening and sorting .dts files for easy comparison, displaying the include tree, etc.
• pinctrl - A more powerful replacement for raspi-gpio, a tool for displaying and modifying the GPIO and pin muxing state of a system, bypassing the kernel.
• piolib - A library for accessing the Pi 5's PIO hardware.
• raspinfo - A short script to dump information about the Pi. Intended for the submission of bug reports.
• rpieepromab - A tool to update and manage the AB EEPROM partitions on a device in the Pi 5 family.
• rpifwcrypto - A command line application and shared library for the firmware cryptography service. Intended for use with Raspberry Pi Connect and secure-boot provisioner.
• rpi-gpu-usage - A tool for showing the per-process usage of the V3D GPU on Raspberry Pi 4 and 5.
• splashasm - A tool for writing spi & i2c dumps for fast display at boot
• vcgencmd - A tool to send commands to the VideoCore firmware and display the results.
• vclog - A tool to get VideoCore 'assert' or 'msg' logs with optional -f to wait for new logs to arrive.
• vcmailbox - A low-level tool giving access the VideoCore mailbox interface.

Build Instructions

Install the prerequisites with "sudo sh prerequisites.sh" - you need at least version 3.10 of cmake. Run the following commands to build and install everything, or see the README files in the subdirectories to just build utilities individually:

• cmake . N.B. Use cmake -DBUILD_SHARED_LIBS=1 . to build the libraries in the subprojects (libdtovl, gpiolib and piolib) as shared (as opposed to static) libraries. Add -DCMAKE_INSTALL_PREFIX=/usr to override the default install path of /usr/local.
• make
• sudo make install
