[etherlab-users] Making the LED stay on in the "user" example

[Matthieu Bec]

Hello Allan,

What do you mean by `stop writing`, stopping the cyclic task?
Slaves usually drop off OP state if they stop receiving frames, yours
might default itself to an Off state that could explain the issue.
Try explicitly setting the watchdog_mode to EC_WD_DISABLE in your
sync_info_t.
