Hello,
I use a LPC 1758 Device with V4.54 for a embedded sensor system. The sensor has an Ethernet interface for data acquiring.
The data is read by two different systems (Hardwar_1, Hardware_2) which reconnected by hand.
Hardware_1: 100 MBit Ethernet Full Duplex
Hardware_2: 10 MBit Ethernet Half Duplex
When plug off the Network Hardware_1, and connect Hardware_2 middleware don't adjust Ethernet speed and duplex. Only solution to communicate with sensor on other speed rate is a soft reset of the processor.
Only the first adapter witch was connected with Sensor works fine.
The Problem was already discussed in 2011: www.onarm.com/.../
I have two questions:
1: is this bug already fixed in MDK 5. Is there a possibility to connect different MACs to the SOC.
2: is there a workaround, to initiate a reconnect with new Autonegotiation with other Ethernet interface while system is running.
With kind regards
David Froelich
I just got this Keil mail, so I assume it answers the question of what networking version you have in 5.20:
