Vinod,
I have attached ... what I think is what you're looking for with regards to the dynamic debug output.
Sorry I should have been clearer. The dynamic debug allows you to enbale debug logs without recompiling
So after boot: echo -n 'module snd_soc_sst_mfld_platform +p' > /sys/kernel/debug/dynamic_debug/control
this will enable prints, so when you start audio, the firmware would be downloaded, and please grab the dmesg ouput and send...
Additionally, the interrupts report as follows... none: $ cat /proc/interrupts | grep sst 7: 0 0 0 0 IO-APIC 28-fasteoi intel_sst_driver
So this makes me suspect interrupts, we should have seen something here
Liam, do you know how whats different in BYT devices from interrupts. I recall Jarkko saying some issues with the way interrupts are exposed..?
