Problems with L2 on samples/net/echo_client and nrf52_pca10040
Flavio Arieta <flavioarieta@...>
I'm having some problems with the echo_client sample while using my nrf52 pca10040.
From what I understood of the problem is that net_if_get_ll_reserve called from net_ipv6_send_nscrashes because of iface->l2->reserve (no function attached to it maybe?).
The project configuration is the default prj_nrf5.conf and no modifications where made on the code apart from some extras debug messages.
Since I haven't changed anything from the configuration and project that could generate this error I'm very confused.
Steps to reproduce the problem:
1. make pristine
2. make CONF_FILE=prj_nrf5.conf BOARD=nrf52_pca10040
3. program the board.

I'm new to Zephyr, so I can lack basic knowledge while configurating the project and with the Zephyr RTOS structure and data flow.
