sample net_sockets_can does not start correctly

[T.B-D]

Hi I try to build the sample 

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.7.1/zephyr/samples/net/sockets/can/README.html

but i get this this error.

Hi rfc

Did you try to apply the pull request I linked to earlier? 

It is a slightly different version of the fix you shared, and this one should be integrated in a future SDK update. 

Back to you Tomas (sorry for the confusion), are you still struggling to build the example? 

Could you try a pristine build and see if that fixes the problem?

Best regards
Torbjørn

Hi Torborn.
With the above sugestion from rfc im able to compile and have the canbus starting now.
I have a machine sending data  (CAN 2.0) with a speed of 250.000 
But as you see it seems that i´m not reciving data.
Any sugestion what to cange ?

Hi rfc
Thank you for your support 

Regards Tomas

Hi 

Have you been able to send data successfully?

Have you checked if there is any communication happening over the SPI bus after the CAN data is starting to arrive?

As a general note you might want to open a new ticket for this different problem, since the devzone is not well optimized for long running threads covering multiple different topics. 

Best regards
Torbjørn
