Hello Chris

How can I report a bug?

we have an application that uses uarts to connect to a TTL camera and it works perfect until we connect a ethernet cable to the board. Once we connect the ethernet cable the data received is incomplete (for example we expect 512 bytes and we only receive 500 or 505, it is random)

Againt if we disconnect the ethernet cable the serial data receieved is ALWAYS complete and the application works perfect.

In our test we are not even using the sockets library.

We believe there is a bug that causes the ethernet connection to mess up the uart transmissions.

Thank you

Pedro

We have the same problem but we found the issue. The serial communication with the camera works ok when the ethernet port is NOT connected. Once a ethernet port is connected to the network the issue appears again. (even if the ethernet libraries are not used)

This problem occurs in the NP2 and  Fez Cobra I, but it does not occur in the fez panda II with ethernet shield.

When the ethernet cable is connected only small data transfer work ok, but large data transfers fail.

Any ideas how to fix this bug???

Thank you

Pedro

We are also experiencing uart/ethernet problems. We have an application that downloads frames from a ttl camera and it works fine if the ethernet port is not connected. As soon as a ethernet cable is connected the application starts failing becasue the data is received incomplete in the uarts.

At this point we are not even using any ethetnet library. 

We need to transfer the frames to a tcp client but until the uart / ethernet bug is fixed we cannot continue.

Please HELP!!!!

We got the ttl camera working on netduino plus 2, however once we connect the ethernet the uart stops working correctly.

When the ethernet port is connected the uarts works for small data transfers but fails for big data transfers like the frames of the ttl cameras.

This is a bug on the netduino plus 2.
