mpremote cp -r command fails with "mpremote: cp: -r not specified; omitting directory"
Port, board and/or hardware
ESP32 on a custom designed ESP32-s3 board
MicroPython version
MicroPython v1.25.0 on 2025-04-15; Generic ESP32S3 module with ESP32S3
Reproduction
- install mpremote using the instructions here.
- run the command
mpremote connect /dev/cu.usbserial-A5069RR4 cp -r configuration/ :configuration/to recursively copy theconfigurationdirectory to the board.
Expected behaviour
I expected the command to recursively copy all files within the configuration directory over to the board to a folder located at /configuration, and to create that folder if it doesn't exist. This expectation comes from the documentation on this page.
mpremote cp -r utils/ :utils/ + soft-reset repl
Same as above, but update the entire utils directory first.
Observed behaviour
The tool returns the following error:
$ mpremote connect /dev/cu.usbserial-A5069RR4 cp -r configuration/ :configuration/
cp configuration/ :configuration/
mpremote: cp: -r not specified; omitting directory
Additional Information
Running on a M1 MacBook Pro, macOS Sequoia 15.3.2.
Using mpremote 1.25.0.
Code of Conduct
Yes, I agree
mpremote cp -r doesn't work
I'm using esp32-s3 on micropython 1.19.1.
On mpremote document.
If you use cp -r, it assumes you can copy whole directory to esp32.
But when I use following command on Windows,
python -m mpremote cp -r main/ :
REPL give me an OSError:
<pre>
cp main/d40.py :main/
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 21] EISDIR
</pre>
