Known Issues

Issue Description
USB EHCI Host port doesn't work on few AM37x EVMs
No workaround
No fix available currently, suggestion is to use TI USB PHY
Pinmux Utility: could not resize the GUI, so could not see what the other button on the bottom right corner is.
User may need to adjust the display resolution of their Windows PC
To be fixed in future releases
Pinmux Utility: could not resize the GUI, so could not see what the other button on the bottom right corner is.
Pinmux utility requires Left-click to select a peripheral interface cell. The cell should be auto selected when user right-click it.
No impact to functionality. Just a note on the user interface.
To be fixed in future releases
AM35x EVM platform booting doesn't continue after below shown messages
AudioPolicyService not published, waiting...
This happens if the Filesystem was not unmounted properly.
Look for the process ID in the console messages.
Kill the process with "kill" command.
This will not appear again.

ARM performance data is not shown sometimes when RowboPERF runs ARM bechmarks
The CPU tests in Rowboat Bench will generate ARM benchmarks, this can be used for same purpose

Netperf Ethernet performance is low when using a buffer size of 8192
No workaround
Other buffer sizes give better performance, see the performance results sheet for this release
System does not obtain IP address automatically after booting
Use netcfg <eth0> dhcp on the console.
See user guide for more details
Graphics Screen resolution is changed after suspend/resume sequence
No workaround
This is only with one of the demo app, this will not affect UI. The other 3D tests in RowboPerf work good.
SUSPEND power consumption is too high (~85mw)
No workaround
To be done
Acquiring different WakeLocks doesn't change power consumption
No workaround
To be done
Video display is not clear when displayed over s-video Not observed on LCD TVs
No workaround
Not consistent on all TVs
Flashing NAND using flash utility v1.3 doesn’t work over UART
USB can be used with same utility to flash the NAND

"Four Dalvik VM unit tests failed during testing
failed: 057-iteration-performance
failed: 062-character-encodings
failed: 063-process-manager
failed: 071-dexfile
No workaround
To be done
When the system is set to display through the S-video output, the display start flickering after a wake-up from suspend
No workaround
To be done
N/A system boot-up takes too long, UI is less responsive, or video playback is sluggish use the SD cards listed in the "SD Card Recommendations" section in the User Guide
