Known Issues

This section lists known issues observed in this release:

Issue Identifier
Issue Headline
Known Workaround(s)
SDOCM00085670 USB: NFS stops working when CDC/RNDIS gadget module is inserted with Arago FS None. This is being tracked as a filesystem issue. http://arago-project.org/cgi-bin/bugzilla3/show_bug.cgi?id=11
SDOCM00085672 AM335x: USB: Video: 640x480 captured image from camera is not clear None. Use lower resolution images.
SDOCM00085673 USB File storage gadget: instability when pendrive connected to host port exposed as storage media from gadget port to PC None
SDOCM00085676 USB: devices connected through a full speed (USB 1.1) hub fail to work in DMA mode Use USB in PIO mode
SDOCM00085830 USB: OTG HNP and SRP not working None
SDOCM00086158 Audio: arecord(version 1.0.24.2) and aplay (version 1.0.24.2) do not work in background Use these utilities in foreground. More information is available here
SDOCM00086520 USB Host port stops enumerating devices after one disconnect / connect cycle Please re-start the VBUS by following the recommended procedure provided in user's guide
SDOCM00085558 AM335x: Allow user to update SPL/Uboot from kernel to NAND None
SDOCM00085659 Nand: 4-bit introduced errors could not be corrected. None
SDOCM00085443 WDT1 timeout inaccurate. None
