I have another Ethernet issue on an RCM6750. I power up the module with an Ethernet cable attached, it powers up fine. I then unplug the Ethernet cable, my app correctly detects the disconnected cable and brings Ethernet down. When the cable is plugged back in, the Net.Lib crashes and the module reboots. Here is what I do: void CheckCable() if ( !pd_havelink( IF_ETH0 ) ) { if (ifpend...


Rabbit 6000: conflict between Ethernet and aux I/O

Hello everyone, I'm new on this group, I look if someone already ask this question but I didn't find about Rabbit 6000. I use aux I/O 16 bit on port A and H and Ethernet connection, but I have many interferences. When I disable ethernet, I read/write with no error, but when ethernet is enabled, I sometimes read a 0 instead of correct data, it seems when there is an ethernet polling. I se...

I have discovered an interesting mode of operation for the Ethernet interface on the RCM3900. With Ethernet configured for DHCP mode, either power up the module without the Ethernet cable plugged in, or unplug it after power up. You will find that after a few minutes the Ethernet controller chip (Asix) gets very hot. Hot enough that you can't keep your finger on the part without burnin...

hello, I have an application where I have to use AUX IO as well as ethernet capabilities of RCM 3000A. While I was testing my code with aux IO disabled and using only ethernet, my computer was able to communicate with rabbit fine. But now as soon as I enable AUX IO, my computer fails to communicate via ethernet. I use Port E bits 0,1,3,4,5 and 6 as strobe.

This is just a piece of info for those using the RCM3200 with a Gigabit Ethernet adapter. I used the Broadcom Ethernet NetXtreme on my Dell Latitude to connect to the RCM3200 ethernet directly using crossover cable and was going crazy trying to figure out why 80% of the time I wouldn't get a LNK light. I then figured out I had to drop the speed down to 100Mbps in the hardware settings to ge...
