Problems with L2 on samples/net/echo_client and nrf52_pca10040

Flavio Arieta <flavioarieta@...>
 

Hi,

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.


Serial output (I can't access pastebin from here, sorry):

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

Hi,

 

Please use prj_bt.conf for nrf52_pca10040. This will give you echo example running over BLE, since nrf52830 present on this DK has only BLE radio.

 

The configuration you have used if for nrf52840_pca10056 and builds the echo example to run over 802.15.4 radio present in nRF52840 chip.

 

 

Kind regards,

Wojtek

Hi Wojtek,


Thanks for your guidance, I played with it for a while and it is exactly as you state on your email.
