mpremote: enter_raw_repl: not working with micropython v1.26

Port, board and/or hardware

esp32-s3, mpremote

MicroPython version

micropython v1.26 with ESP32-S3

Reproduction

mpremote cp process_handler.py :/process_handler.py

Expected behaviour

Should copy

Observed behaviour

mpremote.transport.TransportError: could not enter raw repl

Additional Information

I observed that from being in raw REPL, you cannot initiate a reboot with CTRL-D any more like it was in earlier micropython version.
For reboot, you now need to leave the raw REPL with CTRL-A first before being able to reboot with CTRL-D.

So the behavior of enter_raw_repl in transport_serial.pymight need modification.

Code of Conduct

Yes, I agree

mpremote: Use time delay between copying files in WINDOWS batch file

closedby IhorNehrutsaopened 2021-06-18updated 2022-03-07

tools

I use WINDOWS 10 and ESP32

python.exe mpremote.py connect port:COM8 cp file1.py :
timeout 2
python.exe mpremote.py connect port:COM8 cp file2.py :
timeout 2
python.exe mpremote.py connect port:COM8 cp file3.py :

If timeout less 2 then raise "could not enter raw repl"
