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
Video display is not clear when displayed over s-video Not observed on LCD TVs
No workaround
Not consistent on all TVs
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 fixed in future releases
Acquiring different WakeLocks doesn't change power consumption
No workaround
To be fixed in future releases
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
ARM performance data is not shown sometimes when RowboPERF runs ARM bechmarks
No workaround
To be fixed in future releases
On AM37X, after suspend-resume adb over USB connection is not being reestablished.
Use "adb over Ethernet" when enabling PM
See user guide for more details
Android WiFi
Power Consumption values are higher with Wi-Fi and Bluetooth enabled.
No workaround
To be fixed in future releases
Flashing NAND using flash utility v1.6 doesn’t work over UART
USB can be used with same utility to flash the NAND

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
