"Not Enough Memory" at startup on Raspberry-Pi Pico

[mchobby]

Hi, Just for your information. I did install MWS2 on a Raspberry-Pi Pico and getting Memory issue when starting the main.py example. This error is always happening almost every time (the other time, it starts). I will have a look to the previous version.

Additional information:

• I'm running last nightly build of MicroPython (currently 1.19.1 205)
• Free Mem @ startup : 153296 bytes
• Free Mem after error : 52544 bytes
• Running gc.collect() hangs everything

Here the error:

>>> import main_test

Just work pretty well with the MWS version 1 available at https://github.com/jczic/MicroWebSrv

Build it as a module in your own micropython firmware then only it may work

In my experience, uPy is a memory hog. I've had to either compile frozen modules (include in custom firmware) or use the mpy-cross tool to make .mpy files. https://forum.micropython.org/viewtopic.php?t=4510

@BetterAutomations 👍🏻 That's right.
