Raspberry Pi 5 - Google Coral Edge M.2 TPU installation guide

To get started with either the Mini PCIe or M.2 Accelerator, all you need to do is connect the card to your system, and then install our PCIe driver, Edge TPU runtime, and the TensorFlow Lite runtime. This page walks you through the setup and shows you how to run an example model.

The setup and operation is the same for both M.2 form-factors, including the M.2 Accelerator with Dual Edge TPU.

Requirements

Raspberry Pi 5 with the following Linux operating system:
Raspberry Pi OS (64-bit) based on Debian 10 or newer

Instructions to Update the BIOS/UEFI for an HP Laptop on Linux

To update the BIOS/UEFI firmware requires HP-specific files in the EFI System Partition, also referred to as ESP.

On a Linux system, the ESP is typically mounted on /boot/efi or /efi. Whithin you should also find a EFI directory, e.g. /boot/efi/EFI or /efi/EFI. This article assumes that the ESP is mounted on /efi and that the /efi/EFI directory exists. You can replace that with the mount point your system uses.

The HP-specific files are located in /efi/EFI/HP or /efi/EFI/Hewlet-Packard. These files typically come preinstalled in HP Windows PCs. If you have these files you could skip Install HP-specific files.

What's Cool

Encrypted root partition
- AES-256 bit cipher
- Argon2id variant for PBKDF
- Sha3-512 bit hash
rEFInd bootloader
- With dreary theme
- Optimal Settings (optimized for aesthetics, and boot time)

This uses Linux kernel dyamic debug features

This asumes that debugfs is mounted under /sys/kernel/debug

Enable WireGuard debug

echo 'module wireguard +p' | sudo tee /sys/kernel/debug/dynamic_debug/control
