• chre: This module provides functionality from the Context Hub Runtime Environment to the Wasm runtime.
• libc: C standard library for Wasm.
• memory: Memory access management between Wasm and native code.
• vela-sysroot: A collection of additional header files for building WebAssembly applications.
• vendor: Wasm application SDKs for third-party chip vendors.

How to use

Wasm runtime function module

Currently only WAMR (WebAssembly Micro Runtime) is supported. If you want to use this function module:

1. Enable WAMR in menuconfig.

2. Enable WASM_LIBC (libc) or WASM_MEMORY_OPERATIONS (memory) in the corresponding submenu.

3. The functions of libc or memory are available in the iwasm command line tool and can be used directly in Wasm applications.

Build Wasm applications using SDK

The vendor directory provides a collection of SDKs for third-party chip vendors. Currently, only BL616 from bouffalo lab is supported. To build applications using the SDK, you can refer to the following document: BL616 SDK
