mpremote romfs deploy: Directory handling is arguably inconsistent with cp -r
Port, board and/or hardware
Board independent. Tested on RP2040
MicroPython version
MicroPython v1.25.0-dirty on 2025-04-19; Raspberry Pi Pico with RP2040
Built with romfs
Reproduction
Issue
$ mpremote deploy foo
where foo is a directory on the PC containing subdirectories
Expected behaviour
The command
$ mpremote cp -r foo :
copies the directory foo with contents and subdirectories to the host. This is consistent with
$ cp -r foo bar
Observed behaviour
By contrast
$ mpremote deploy foo
copies the contents of foo as per
$ cp -r foo/* bar
A typical project might consist of a Python package foo where the executable foo is contained in a directory holding documentation and other resources. The requirement is to copy foo and its contents. Currently this requires a workround involving a temporary directory and a symlink.
Additional Information
Options are either to change this behaviour or provide means of deploying either the directory + contents or contents alone.
Code of Conduct
Yes, I agree
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.
