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..? -- ~Vinod > > Tyler > > On 07/07/2015 01:08 PM, Vinod Koul wrote: > >On Tue, Jul 07, 2015 at 10:00:31AM -0400, Tyler Yeomans wrote: > >>Vinod, > >> > >>I am using the ssp0 firmware from: > >>https://git.kernel.org/cgit/linux/kernel/git/vkoul/firmware.git/tree/intel?h=byt. > >Hi Tyler, > > > >Can you enable logs (dynamic debug should help), I want to see if FW > >download was success or not > > > >Also cat /proc/interrupts to see if we are getting interrupts > > > >Thanks >
