SX-SDCAN

SX-SDCAN

Hi,
I don't know if anyone else has near the same configuration as me - but I've been trying to enable the SX-SDCAN module for my imx6q sabre auto board. I've searched google and come up with a few things but none resulting in a fix, and am going to contact the manufacturer to see if they can help.
I've built up an image based on core-image - I haven't configured the kernel but Atheros ath6kl support is enabled as a module.

I was wondering if anyone has had experience with it (and more particularly success?)
During the board's boot cycle it gives the following messages:ath6kl: Failed to get board file ath6k/AR6003/hw2.1.1/bdata.bin (-2), trying to find default board file.ath6kl: Failed to get default board file ath6k/AR6003/hw2.1.1/bdata.SD31.bin: -2ath6kl: Failed to init ath6kl coreath6kl_sdio: probe of mmc1:0001:1 failed with error -2
And, these are the contents of /lib/firmware/ath6k/AR6003/hw2.1.1, so it seems to have the things I need there:athwlan.binbdata.SD31.binbdata.SD32.binbdata.WB31.binbdata.bin -> bdata.SD31.binbdata.patch.binendpointpoing.binfw-2.binfw-3.binopt.bin
Any help would be much appreciated!

So, you do have the module (*.ko) and you do have the firmware. I think 
you have everything needed. The only missing piece would be the wifi 
tools to control it.

What's your board? What changes did you make?

This is not exactly the right place to get help on this kind of issue 
(as it does not related with yocto). Have you tried to post your 
question in imx-community?

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.

SX-SDCAN Ath6kl firmware

[Morgan McKenzie]

[-- Attachment #1: Type: text/plain, Size: 4253 bytes --]

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!)

Morgan McKenzie

I'd like to understand the issue so we may try to come up with a fix
for it. I don't have a SabreAuto board myself (neither the WIFI
adapter) but I have some understanding about Linux and Yocto Project
and may be able to help.

Could you explain me how did you get to the conclusion it is an order issue?

Hi Otavio,
To be honest I'm not completely sure about it being a timing issue, it's just my best guess. When the board boots up it hangs and isn't able to load the module, but if I log in, rmmod the module, and insmod the module, it works. All the error messages I get during boot are relating to the module file not being found, which makes me think that the file system isn't ready (or perhaps some other system service - maybe udev??).
Unfortunately I've been swamped with work the last few days and haven't been able to take too much of a look at it. I'll be spending some time on it over the weekend so I will probably have a better idea by Monday.
Thanks for your interest! 
Regards,
Morgan McKenzie

Hi Otavio,

I'm sorry I left this on the backburner for so long - I solved the problem a little while ago and I've been meaning to send this and just haven't had the chance. 

I've managed to solve the issue to my satisfaction; I have the board booting and reliably connecting to wifi. However, I don't think that the way I did it would qualify at all for being put back into the repo. For anyone else who might be having/might have the issue, this would probably help though...
in blacklist.conf, which goes in /etc/modprobe.d/:>    install ath6kl /bin/false(note that just doing an ordinary blacklist actually still resulted in it trying to load when the sdio was recognized, which caused the boot sequence to hang for 60 seconds as the module searched for the board data file, so I had to force it to fail...)
And then in an init file, which ignores the blacklist:>   modprobe --ignore-install ath6kl

Which kernel version did you try? Have you tried with 3.10.17? or even
newer as 3.14?
