2010-08-16 07:53:07     Why isn't sound enabled in the BF518F image?

I was surprised to learn that the audio codec was not enabled in the distribution uImage for the BF518F EZ board.  Is there a particular reason that it was not enabled (such as "because it doesn't work")?

 

Is it as easy as following the instructions given at https://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:ssm2602?

 

Should I anticipate any issues getting this to work on rev 0.0 hardware?

the BF51x focus has been on RSI and PTP.  i'm not sure we've looked at the sound codec too much.

 

you'll have to add asoc platform resources to the board file so that enabling the drivers would work ...

OK thanks.  I'll go work on that.  I presume that you mean I shall have to modify arch/blackfin/mach-bf518/boards/ezbrd.c and that it should be pretty obvious what needs to be added based on working examples.  (An example "working example" would be welcome here.)

 

Would you like a patch file when I'm done?  Should it be against trunk or against the 2009R1.1-RC4 distribution?

yes, that's the file & what you need to do

 

the bf537-stamp should have plenty of examples, but the bf527-ezkit might be easier to use since it has a ssm codec

 

patches are always welcome even if we dont accept them (not that we wouldnt here) ... trunk would be best since it's going to be released soon
