AI Pyramid Software Package Updates

1. Preparation

The factory image already includes the M5Stack APT repository. If you need to add it manually, refer to the following steps.

wget -qO /etc/apt/keyrings/StackFlow.gpg https://repo.llm.m5stack.com/m5stack-apt-repo/key/StackFlow.gpg
echo 'deb [arch=arm64 signed-by=/etc/apt/keyrings/StackFlow.gpg] https://repo.llm.m5stack.com/m5stack-apt-repo jammy ax650c' > /etc/apt/sources.list.d/StackFlow.list

2. Update Software Sources

Step 1: Update the Package List

Run apt update to update the package list:

apt update

3. Install Software Packages

Step 1: View Available Packages

Check the list of available llm deb packages. Packages named in the llm-model-name format are model packages, while those named llm-name are functional module packages.

apt list | grep llm-

Step 2: Install Required Packages

Install the required packages using the apt command as needed, for example, installing the llm-cosy-voice package. Note: Model packages occupy a relatively large amount of storage space. It is recommended to install them on demand.
