ADL-N DSP boot failure

[brentlu]

We received a broken ALD-N Chromebook device which audio DSP always fails to boot. The failure rate is 100% and so far we couldn't find another device with same symptoms.

Linux kernel log suggests there is error returns from SOF_IPC_DAI_CONFIG(0x80010000) command: linux.txt

Can you double-check the topology settings @brentlu ? Wondering why what the changes are for this platform?

[brentlu]

There is nothing special for this topology. The only difference is that MCLK rate is 24.576MHz but this setting has been long used in max98373 topology.

"sof-tgl-max98357a-rt5682\;sof-adl-rt5650\;-DUSE_RT5650\;-DFMT=s24le\;-DPLATFORM=adl\;-DLINUX_MACHINE_DRIVER=sof_rt5682\;-DAMP_SSP=1\;-DSPK_MIC_PERIOD_US=10000\;-DBT_OFFLOAD\;-DNOHOTWORD\;-DNO16KDMIC"

[brentlu]

DSP panic could be observed with same FW image. The exception cause LoadStorePIFDataErrorCause also suggests that there is problem with the memory. So my question would be "is there anything we can do / need to do about it?". If not, I would suggest ODM to go through CQE process for further analysis.

[plbossart]

My guess is that you have a conflict between SSPs, specifically I am not sure if you can have BT_OFFLOAD along with the MCLK at 24.576?

Can you try and force the nocodec mode to see if you are able to use the SSPs in default mode? that would point to a problem in the topology or SSP setup.

#define SOF_DBG_FORCE_NOCODEC           BIT(10) /* ignore all codec-related  configurations */

[brentlu]

Memory corruption could be observed even on nocodec mode. I print the variables of same structure and found the value would change. It seems to me that there is something wrong with the memory.
