KNOWN ISSUES
Hardware
The PCIe Minicard and the two PCIe Express ports on the PCIe/104†OneBank†connector are
connected to an on-board PCIe Gen2 Switch (a PLX PEX 8605). Certain older, non-compliant Gen
1 devices will not link up properly with this switch (such as the Startech MPEXSATA221
PCIe-to-SATA bridge using a Silicon Image Sil3132 bridge).
Holding the reset button in when powering on the board prevents booting and requires a re-power.
Make sure the reset button is not being asserted low when powering on the board.
If the +5 V input voltage is low (below +5 V) and the wires to the power supply are long (greater
than 12 inches) or too low of a gauge (less than 16 AWG) the board may take longer to power on
due to in-rush current causing a droop on the + 5 V power at the power connector input. This
droop in the +5 V power causes the board to switch the regulators off and then back on again.
Typically, this results in only a short delay (less than 1 second). Users should measure the +5 V
power at the connector with their particular power delivery system to see if the voltage at that point
ever drops below about +4.75 V when power is applied.
BIOS
S3 wake using power button may require keyboard/mouse activity to turn on the display.
The first display port (J3) can also support HDMI (it is a DP++ port). To support HDMI there are
two options:
Use an active DP-to-HDMI adapter
Use a passive DP-to-HDMI adapter and request a custom BIOS from VersaLogic.
Legacy USB support is not available in xHCI (USB 3.0) mode. Non-UEFI pre-OS and installation
environments may require EHCI (USB 2.0) mode for USB keyboard functionality.
Operating Systems
Driver support (via VersaAPI) for SPX-5 module and I2C PWM output are not yet available.
