[meta-freescale] SX-SDCAN Ath6kl firmware

[Morgan McKenzie]

Hi all,

I sent a message a while about getting an SX-SDCAN module working on a i.mx6qSabreAuto board.  Several months later with a lot of banging my head against various walls (or at least that's what it seemed like) I believe that I've finally figured out what was going on -  it is configured to load as a module in my kernel configuration due to something else it requires also being a module; and as far as I can tell, module is trying to load before the file system is fully ready (or something like that) and therefore cannot find the required board configuration files.
So if anyone runs into a problem with this chip in the future that's at least a possible cause. I'm going to try to figure out a good way of solving the problem and supply a patch if I can - but to be honest I don't know nearly enough about Yocto/linux to do it properly so that might not happen.. (if anyone else has any good ideas on that I'm very open to suggestion!)

Regards,
Morgan McKenzie

Hi,
Thanks for the feedback, I was thinking of posting there but hadn't got around to it yet. It's weird - I used to have it working with LTIB back a few months ago (well, almost a year) and I have a really similar configuration on the board now.
Anyways, thanks for your help - hopefully someone in the imx-community will know.
Regards,
Morgan McKenize
