zephyr: unable to build simple example targeting the nucleo_f767zi board with libc wasi #2846

Open deadprogram opened 10 months ago

deadprogram commented 10 months ago

I am trying to build the product-mini/platforms/zephyr/simple example targeting the nucleo_f767zi board with WAMR_BUILD_LIBC_WASI so that a WASM module compiled for wasi can execute on the board itself.

This is the command I am trying to use to build:

ZEPHYR_BASE=~/zephyrproject/zephyr west build -b nucleo_f767zi . -p always -- -DWAMR_BUILD_TARGET=THUMBV7 -DWAMR_BUILD_LIBC_WASI=1

However, the code is unable to build without errors:

Any ideas? Thanks in advance!

If I try to execute my WASM code compiled targeting wasi but without the WAMR_BUILD_LIBC_WASI=1 I get the following log from the board after flashing:

Connected to /dev/ttyACM0. Press Ctrl-C to exit.
*** Booting Zephyr OS build zephyr-v3.5.0-2399-gc94cd30cecbf ***
WASM module instantiate failed: allocate memory failed

If I compile iwasm for Linux, and I set WAMR_BUILD_LIBC_WASI 0 then I get the following error:

$ ./iwasm ../../../app-samples/hello-world-tinygo/test.wasm 
[16:13:34:719 - 7FCAE7617B80]: warning: failed to link import function (wasi_snapshot_preview1, fd_write)
Exception: lookup the entry point symbol (like main, _main, __main_argc_argv) failed

If I compile iwasm with WAMR_BUILD_LIBC_WASI 1 then the code executes as I expect:

$ ./iwasm ../../../app-samples/hello-world-tinygo/test.wasm 
Hello world!

@deadprogram thanks for reporting! I've been working on the zephyr support and will look into this!

deadprogram commented 10 months ago

Thanks @hasheddan

Hello @hasheddan any updates on this by any chance? :smile_cat:

@deadprogram thank you for the ping and my apologies on the delay here! I have just opened #3086 to address the primary issue you encountered here, but am also investigating additional rough spots regarding WASI support with Zephyr. Feel free to try out the patch and report any further problems you encounter!

Hello, I have the same issue with build to qemu_cortex_a53 :( I am running the latest wamr version (I've just pulled from main branch)

srberard commented 7 months ago

Is there any update on this issue? I'm having similar problems building with WAMR_BUILD_LIBC_WASI 1 on Zephyr. I'm still targeting WASI preview 1 so I'm on the release/1.3.x branch.
