[BBB.IO] new to MTP, File (Create/Save) access issues?

[RobertCNelson]

Thanks for this wonderful project, i just discovered it today while trying to solve one of our age old, "out of box" configuration problems we have at BeagleBoard.org..

I've got things mostly working, just really a quick question on MTP or maybe my config is messed up.. With a Windows 10 host, we can correctly create Folders, Drag Drop Files and Rename Files..

But i can't seem to "create" a new file (or open, edit and "save" as the same file name), is this normal in MTP or did i mess things up?

My Default config for uMTP is:

https://github.com/rcn-ee/repos/blob/master/bb-usb-gadgets/suite/bullseye/debian/bbb-umtprd.conf

Our gadget "mess" is this script for reference:

Using:

[uMTPrd - 21:44:14 - Info] Version: v1.4.3 compiled the Oct 8 2021@18:04:33

and daily builds for BeagleBone Users:

https://rcn-ee.net/rootfs/debian-armhf/ (any date on or after: 21-10-08/ has MTP enabled by default..)

I'm working on polishing our Bullseye release..

Thanks!

File creation should work. Please enable the debug mode at the compilation (CFLAGS="-DDEBUG") and share the logs with one file creation attempt.

I'll also try on Linux, as Windows just doesn't show the option

Very strange, so in Linux, NEMO allowed me to write the drive.. Should we be using a third part application in Windows 10 maybe? My laptop is running Windows 10 Enterprise, 20H2.. (corporate laptop..)

[jfdelnero]

According to the windows logs it appears that the file is correctly created. am i missing something ? Are you trying to save something to this file ?

[RobertCNelson]

So "Original.txt" was "drag" n "dropped" via Windows.. I guess i'm expecting the ability to Right click and "add new File" or even "open" and then save in the same directory??

(picture attached..)

Can you try the same operation with an android smartphone ?
