NDK
Support Package for EVMDM6437
Changes
Introduced in Version 1.92 (from Version 1.91)
Supported Platforms / Devices
- The following platforms are supported:
Example Programs
Functional Changes
- The NDK Support Package for EVMDM6437 is
delivered separately from NDK itself.
Bug Fixes
- Modified checking through PHYs present from ALIVE register instead of Link
Register
Known issues
- On the DM6437 EVMs, the PHY address
(should be 0x1) is not latched correctly on power up. As a workaround on
these boards, the build batch file overrides the default PHY_MASK value
with mask value corresponding to PHY address zero (which is the default
with this release). On boards with fix for correct PHY address reset the
PHY _MASK value in makehal_evmdm6437.bat to 0x2.
- For Socrates Visualization, please ensure
that the log library included is “log8.a64P”
Observations
- With certain PC network interface cards, only Half-duplex mode
will be negotiated if auto-negotiation is not chosen on the PC side. On
such cards if 100 Mbps full duplex is chosen, the interface instead of
reporting 100Mbps full duplex capability alone during auto-negotiation,
defaults to not using auto negotiation at all.
- Approximately 2 % packet loss is observed
with ping packets when used from a Windows Platform. However no drops are
seen for flood ping & ping from Linux machines.
