I've been trying the nightly builds for the RockPro64. They mostly work, but I can't access windows shares - I had to test using a USB drive. The same shares work fine with recent releases of LibreELEC.
I turned on debug logging and saw the following:
18:01:27.525 T:4070839072 ERROR: GetDirectory - Error getting smb://USERNAME:[email protected]/AV/
18:01:27.525 T:4070839072 ERROR: CGUIDialogFileBrowser::GetDirectory(smb://USERNAME:[email protected]/AV/) failed
I used "Add Network Location" and the correct USERNAME and PASSWORD are set (I double checked this.) I suspect that for some reason these development releases are not passing the correct parameters to SMB.
If this is not the right place to report this, please let me know.
