Question

The --usb_host flag is no more active in build.py

It has been removed in PR #4313 in commit 2977d0c

Is there any plan to add the USB Host support again ?

In fact I would like to clean-up ST USB Host files but I need to build and test my modifications...

Could you just add a --source <path-to-usb-host>? That should do exactly the same thing as the flag would have.

[bcostm]

Thanks for the tip. Using --source flags, the build is now OK.

My command for reference is:
python ./tools/build.py -v -x -j 4 -m NUCLEO_F429ZI -t ARM --rtos --usb --source . --source features\unsupported\USBHost --source features\unsupported\USBHost\USBHostHID --source features\unsupported\USBHost\USBHost --build BUILD

But now I have an issue with make.py:
python ./tools/make.py -m NUCLEO_F429ZI -t ARM -n USB_1 --usb

Note that I have replaced the main.cpp file for USB_1 test by the main.cpp found in tests/usb/host/mouse (previously USB_11 test).

[Error] USBEndpoint.h@22,0: #5: cannot open source input file "rtos.h": No such file or directory

This points me to the comment in commit 2977d0c

usb host has dependency on rtos1 that is no longer in the
code base.

So, effectively I think I cannot use USB Host for now.

[theotherjimmy]

You're welcome.

That does look like a blocking issue. If it really does depend on rtos1, then it should not have compiled without the rtos. Hmmmmmm, strange.

This is the command I use to build it successfully

Thanks! It works for me too using this command.
