Known Issues


PHYTEC Known Issues

  • Boot tests showed in about 2 of 2000 boots that the SMSC LAN8710 phy could not be found. The PHY ID readout is wrong. The generic PHY driver will take over. Ethernet is still functional is this case.

Texas Instruments Known Issues

  • See here for a list of TI's known issues for their SDK 7.0 kernel 3.12 release. PD15.2.1 is based on kernel 3.12.30 from TI.
