Re: J1939 + iMX6 + yocto

[Kurt Van Dijck <dev.kurt@vandijck-laurijssen.be>]

Hi Pascal,

I got back to my PC now.
I see how the j1939-v3.10 branch dissapeared. I had pushed it
to gitorious.org, which is obsolete now, thinking that I had pushed it
to github. I set that right just now.

> Which platform do you use?
We have a custom iMX6 platform (in-house developed), with the core
similar to sabre-lite from Boundary Devices (They have renamed that
board now). Our board has 2 SJA1000 chips added.

I also updated iproute2-j1939, to a version that is equal to what yocto
is using now. This was less effort than choosing a different version
of iproute2 in yocto (to me).

Kind regards,
Kurt
