On ESP32: Out of memory with quite a basic setup? about microdot HOT 4 CLOSED

Is there any chance any of the 436 lines that precede your microdot import are consuming a large part of your memory? You are calling this a "basic setup", but my definition of basic setup would be that you run the web server on its own. These devices have limited resources. If you don't pre-compile your sources, then you must import the largest files first, so that there is more memory available to the compiler. Or else, you should seriously consider pre-compiling, or better yet, freezing as much of your code and libraries as possible.

Thanks for answering so fast...

I had more code working before I encountered this problem. I stripped my code down to basically the minimum. In the 437 lines are functions that are not being used, that makes it so long. I have removed that function now, still with the same result. I even deactivated webrepl.

Could it be that there is a chain of exceptions within your code, each exception consuming heap space or something?

import threading

fails when I try that in the repl

Can I turn on debug somehow? I am not that familiar with micropython yet..

@hagenbuch Most MicroPython ports do not have threading. It is expected for that import to fail. If you are getting any errors, you have to show me the statements that you issued and the errors if you need me to comment on them.

I would suggest that you take hello.py from this repository and save it as your main.py, and see if that works or not. And as I said, if you get any errors, copy the full output here.

See https://microdot.readthedocs.io/en/latest/freezing.html for information on how to cross-compile and/or freeze your application and dependencies to reduce the memory footprint.
