ShaneCCC,
during the compilation of the DT (that I though it went OK)
/usr/src/kernel/kernel-4.4$ make dtbs
The printing out displayed something like this:
DTC arch/arm64/boot/dts/_ddot_/_ddot_/_ddot_/_ddot_/_ddot_/_ddot_/hardware/nvidia/platform/t18x/quill/kernel-dts/tegra186-quill-p3310-1000-a00-00-base.dtb
DTC arch/arm64/boot/dts/_ddot_/_ddot_/_ddot_/_ddot_/_ddot_/_ddot_/hardware/nvidia/platform/t18x/quill/kernel-dts/tegra186-quill-p3310-1000-a00-00-ape-cam.dtb

...
instead of
DTC arch/arm64/boot/dts/../../../../../../hardware/nvidia/platform/t18x/quill/kernel-dts/tegra186-quill-p3310-1000-a00-00-base.dtb
...
The dots some how turned into letters, so eventually instead of going up the directory tree it created sub-directories by the name ddot
any suggestions?
ShaneCCC,
I saw that in a Makefile that the ddot
I have finally succeed to compile a DT from source files (as opposed to from a de-compiled file source).
The terminal provides the following failure:

any suggestions?
That’s strange, how do you apply your DTB? by flash the DTB partition? Did you see this message without any DTS modify?
ShaneCCC,
Nothing strange when you flash the correct DT…
[ 3.640528] tegra-snd-t186ref-mobile-rt565x sound: ASoC: CPU DAI DAP not registered
[ 3.640531] tegra-snd-t186ref-mobile-rt565x sound: snd_soc_register_card failed (-517)
what is this DAP that I did not provide.
Thanks.

ShaneCCC,
cpu-dai=<&tegra_i2s1>
now I was informed by the code that the
ASoC: CODEC DAI tlv320aic32x4-hifi not registered
I think that I need to provide somewhere a structure which defines this CODEC DAI, though I’m not sure where…
can you assist?
Thanks.
Hi Igal,
There error code …
[ 3.640531] tegra-snd-t186ref-mobile-rt565x sound: snd_soc_register_card failed (-517)
… is defined as follows …
#define EPROBE_DEFER 517 /* Driver requests probe retry */
This is a normal error and means that we were unable to complete the probe because something is missing not register yet (ie. the codec) and the kernel will retry the probe again later. So do you see the kernel attempt to probe the sound card again after the codec has registered?
