See my comment to the second issue: the code runs OK and it seems to be an IDE problem.

You're right. I verified that too. Thank you.

I am having frequent hang as well. Cannot connect to REPL and cannot break out from a loop with CTRL-C. Since then I - Do not run main loop in main.py. Expose run() function to manually start from REPL. - Use SWD to upload frozen code. - Connect reset switch to rp2. Related issues: https://github.co...

The code ret(v) is running a generator function, instantiating a generator, and then discarding the generator. This is an unusual thing to do in a loop. While your observation is very odd, I'm not sure whether the performance of a generator function (rather than a generator) would be seen as a crit...

import time def ret(arg): yield None def test3(klass=int, count=10000): for n in range(count): v = klass() ret(v) def test4(v=0, count=10000): for n in range(count): ret(v) t = time.ticks_ms() test3(dict) print('dict(): ' + str(time.ticks_diff(time.ticks_ms(), t))) t = time.ticks_ms() test3(int) pr...

Similar problem is on github issue now.

Similar result with yield: import time def ret(arg): yield arg def test3(count=10000, d=False): for n in range(count): if d: v = dict(a=0) # list() object() else: v = int() # 0 r = next(ret(v)) t = time.ticks_ms() test3(d=True) print('dict(): ' + str(time.ticks_diff(time.ticks_ms(), t))) t = time.ti...

I found a weird performance issue. In async functions, it is a lot slower when returning scalar types than object types. import time import uasyncio as asyncio async def ret(arg): return arg async def test3(count=10000, d=False): for n in range(count): if d: v = dict() # list() or object() else: v =...

rp2 port is missing FROZEN_MANIFEST option. Just made PR request https://github.com/micropython/micropython/pull/8280 for this. For the moment, this is part of my build script: ... # modify rp2 manifest file # https://docs.micropython.org/en/latest/reference/manifest.html?highlight=manifest MANIFEST...

Thank you. Problem solved.

It seems PYTHONPATH is not recognized by unix port of micropython. How do you set import path for unix micropython, without modifying source code? And if I have to modify sys.path for unix micropython, where is good place put the code? Is there a bootstrap script for unix port? I want to use unix mi...
