This repo contains the source code for the userspace level runtime driver for Coral devices. This software is distributed in the binary form at coral.ai/software.
At present only Bazel build system is supported. For
proper environment setup check docker directory.
Build native binaries on Linux and macOS:
$ make
Build native binaries on Windows:
$ build.bat
Cross-compile for ARMv7-A (32 bit), and ARMv8-A (64 bit) on Linux:
$ CPU=armv7a make
$ CPU=aarch64 make
Build Linux binaries inside Docker container (works on Linux and macOS):
$ DOCKER_CPUS="k8 armv7a aarch64" DOCKER_TARGETS=libedgetpu make docker-build
All built binaries go to the out directory.
If you have question, comments or requests concerning this library, please reach out to coral-support@google.com.
If you're using the Coral USB Accelerator, it may heat up during operation, depending on the computation workloads and operating frequency. Touching the metal part of the USB Accelerator after it has been operating for an extended period of time may lead to discomfort and/or skin burns. As such, if you enable the Edge TPU runtime using the maximum operating frequency, the USB Accelerator should be operated at an ambient temperature of 25°C or less. Alternatively, if you enable the Edge TPU runtime using the reduced operating frequency, then the device is intended to safely operate at an ambient temperature of 35°C or less.
Google does not accept any responsibility for any loss or damage if the device is operated outside of the recommended ambient temperature range.
Note: This issue affects only USB-based Coral devices, and is irrelevant for PCIe devices.
