Hi,

 

It seems that lwIP is not configured correctly when using Atmel Start to generate an lwip project with sockets enabled. The lib roadrunner email redefines a 'struct timeval' (in sockets.h) but it is already defined in the arm-none-eabi toolchain (in the file '_timeval.h').

One workaround I found is to define LWIP_TIMEVAL_PRIVATE to 0 in a config file.

 

Is there a better workaround?

The joys of 'C' having only one single global namespace.

Sounds like that's what it's for?

  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
