Sample TCP client code fails with:

[Client] Create socket

Environment

• Host OS: esp32-cam

There isn't sufficient information to draw a definitive conclusion; this is just a wild guess.

According to the log, the error code is returned by the socket() function. Typically, EACCESS indicates "Permission to create a socket is denied." And in the case of Wasm, this error may also indicate an incorrect WASI context, which could include (but is not limited to) incorrect command line options for iwasm, or failed calls to WAMR APIs.

For a quick verification, you should try running a similar socket example in the form of a native binary to isolate any potential effects from wasi-libc.
