i'm using banana-pi-m2+

already enable i2s0 by changing dtb file in /boot/dtb and can see i2s module load

but aplay -l still not showing 

anybody help?

I manage to get this working using released Armbian 5.65 (kernel 4.14.78).

Somehow armbian kernel never include pcm5102a driver module, so have to compile it manually as compiling via menuconfig also not working (Kconfig not include "CONFIG_SND_SOC_PCM5102A=m" ).

After successfully compiled snd-soc-pcm5102a.ko (see attached file), copy it at /lib/module/kernel/4.14.78-sunxi/kernel/sound/soc/codecs/

Copy sun8i-h3-I2S-out.dts (attached file) in /boot/overlay-user and convert it to dtbo file with armbian-add-overlay

Enable i2s in board dtb (for my board sun8i-h3-bananapi-m2-plus.dtbo).

You have to convert dtbo file to dts file first to be readable and change to "status = "okay";" under i2s@01c22000 section

(see attached sun8i-h3-bananapi-m2-plus.dts) and convert it back to dtbo file.

After reboot then pcm5102 i2s device will show up :)

Could you please tell how how did you compile snd-soc-pcm5102a.ko?

On my NanoPi Neo I

- changed the .dtb for the Neo

- did armbian-add-overlay ./sun8i-h3-I2S-out.dts

- now have in armbianEnv.txt: 

   user_overlays=sun8i-h3-I2S-out

- lsmod|grep i2s
     sun4i_i2s              16384  0
     snd_soc_core          118784  2 sun4i_i2s,sun8i_codec_analog
     snd_pcm                69632  3 sun4i_i2s,snd_pcm_dmaengine,snd_soc_core  

 

I think I do only need the .ko in my system - compiled for

ARMBIAN 5.65 stable Debian GNU/Linux 9 (stretch) 4.14.84-sunxi

Linux npi-neo 4.14.84-sunxi #3 SMP Sat Dec 1 07:18:41 CET 2018 armv7l GNU/Linux

 

I did try to see it in "only U-Boot/kernel" in the armbian-build-system - BUT failed :(
I did see that kernel-menuconfig, but dont know what to do with it and the patch:

 

 

For the Neo I have the PCM5102A-Hat from FriendlyARM

https://www.friendlyarm.com/index.php?route=product/product&product_id=169

and it is/was running fine with legacy kernel 3.4:

You have to modify config PCM5102A like below on  cache\source\linux-mainline\v4.14.84\sound\soc\codecs\Kconfig

config SND_SOC_PCM5102A
    tristate "Texas Instruments PCM5102A CODEC - I2S"

then replace config-default.conf with attached

With this conf, script compilation will stop to overwrite kernel source to build patch

At that time, overwrite original Kconfig with the one you modified above

Then script compilation will stop again to ask whether you want to add pcm5102a to compile

Default is N, so you need to enter m for module compilation

 

config-default.conf.mod

I did all this - after getting it into my brain the last night - AND IT WORKED :) Many Thanks!

BE HAPPY about a successful i2s mapping in dmesg (on NanoPi Neo)

I did wrote a new thread for the NanoPi Neo - it could be better found if anyone does earch for the information :
