Which version of MicroPico are you using?

I've tried multiple versions latest is:
MicroPython v1.22.1 on 2024-01-05; Raspberry Pi Pico W with RP2040
Type "help()" for more information.

Wrote a simple program that prints "sleeping 1" every second. Used listen2pico.py to test

@markt22 Thanks for testing. So it seems like that for some reason on your system the micropython pyboard tool is unable to enter raw repl mode. It could help if you have a serial console program like minicom and connect to your board and press Ctrl+A and send me the output.

raw REPL; CTRL-B to exit

[paulober]

if you first press ctrl-c (maybe twice) and then ctrl-a?

[markt22]

ctrl-c ctrl-a, gets the 'raw REPL' response
ctrl-a ctrl-c, gets the 'raw REPL' response
ctril-c ctrl-c ctrl-a gets the 'raw REPL' response
But ctrl-a only, the program keeps running.

I downloaded pyboard from micropython tools, it only sends ctrl-a (assuming --no-soft-reset) which doesn't interrupt the running program, also because my program is printing out the serial port read_until never times out.

[paulober]

ok, thanks for doing all of the testing. So maybe the lib doesn't stop the executing program correctly.

[markt22]

is your wrapper using pyboard to provide the commincations layer?

[paulober]

right.
I just looked at the initialization and the wrapper should cancel all running programs correctly (so I assume).

[markt22]

Now Added a virtual serial tap between the micropython board and wrapper code

This chunk of data is out of the buffer it is just multiple instances of 'sleeping 1'

###Looking at pyboard.py code
The 04 reset command is sent in (which is default behavior). There is a --no-soft-reset option in the pyboard.py code, which bypasses this code:

if soft_reset:
        data = self.read_until(1, b"raw REPL; CTRL-B to exit\r\n>")
        if not data.endswith(b"raw REPL; CTRL-B to exit\r\n>"):
            print(f"DEBUG 1 {data}")
            raise PyboardError("could not enter raw repl")

        self.serial.write(b"\x04")  # ctrl-D: soft reset

maybe its's somehow connected to this issue - #197 ?
