[Bug] NXT REPL hangs or craches after a command is entered #2272
Description
Utterly premature, but maybe still good to report now.
Describe the bug
What is the problem?
Starting at pybricks-micropython build "3931 pbio/protocol: Add slots info to hub capabilities and status."
the REPL hangs or crashes.
Flash was done with pybricksdev v1.2.0
To reproduce
Scenario-1 starting with the REPL active:
- type
print()and [enter]
terminal goes to the next line and crash (NXT display empty) or a hang.
Scenario-2 starting with the REPL active:
- press CTRL-A
- press CTRL-B
- press CTRL-D
- press CTRL-C
this goes all fine. - press CTRL-E
- type
print()and [enter]
all OK the prompt===is presented each [enter]. - press CTRL-D
terminal goes to the next line and crash (NXT display empty) or a hang.
Did not try to paste any command in raw paste mode.
Sometimes (not so easy to hear) after the hang /crash there is clicking (twice per second) where the reset click is once per second.
Expected behavior
What did you expect to happen instead?
Normal micropython response for the command.
