WASM module instantiate failed: allocate linear memory failed

[maelp]

I'm trying to build a minimal (non-WASI, for esp32s3) example using the code you display, but it doesn't work, do you have an idea?

Reproduction on this branch: https://github.com/maelp/espidftemplate-with-wamr/tree/feature/add-simple-wasm-plugin/

./build_plugins.sh && ./build_flash_monitor.sh

it shows this

Hmmm when requesting less memory I then have a crash

Same here.
esp32 crashed after wamr call os_self_thread()

{
    uint8 *stack_boundary = os_thread_get_stack_boundary();

#if WASM_ENABLE_THREAD_MGR != 0
    os_mutex_lock(&exec_env->wait_lock);
#endif
    exec_env->handle = os_self_thread(); <<< Crash here!
    exec_env->native_stack_boundary =

}

@AlixANNERAUD I don't know if you have managed to build it on your side perhaps?

[darkautism]

I fix this issue by add a ext function

In your Cargo.toml:

wamr-rust-pthreadcall = { git = "https://github.com/darkautism/wamr-rust-pthreadcall" }

In your code:

// Add ext
use wamr_rust_pthreadcall::PThreadExtension;

    let params: Vec<WasmValue> = vec![];
    let result = function
        .call_pthread(&instance, &params) /// Change call to call_pthread
        .expect("Failed to call WAMR function");
    log::info!("Program exited with code: {:?}", result);
