Hi,

 

I know it's a waste of time to play with an old bananapi pro but I think I could do it so I want to do it !

 

I can't make working PCM5102a DAC.

I read a lot of things through different website but noway !

 

I tried https://forum.armbian.com/topic/9009-info-friendlyarm-pcm5102a-hat-with-nanopi-neo-under-mainline-4xx/ .

I've only obtain this next to the step "armbian-add-overlay ./sun8i-h3-I2S-out.dts":

$lsmod|grep i2s
sun4i_i2s              20480  0
snd_soc_core          114688  2 sun4i_codec,sun4i_i2s
snd_pcm                69632  4 sun4i_codec,sun4i_i2s,snd_pcm_dmaengine,snd_soc_core

I tried the next step but nothing more: dmesg|grep -i pcm keep empty.

 

I tried to make a module with this tuto https://hackaday.io/project/162373/instructions with the make command and his model of pcm5102a.c file, nothing more.

I tried too with https://github.com/torvalds/linux/blob/master/sound/soc/codecs/pcm5102a.c

failed !

 aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sun4icodec [sun4i-codec], device 0: CDC PCM Codec-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Anyway ! Where I am wrong ?

Is there a step that I do well ?

sun8i-h3-I2S-out.dts is not the correct dts for this board, it should be a sun7i-a20 file if it exists 

oh yes, for sure, I modified the sun7i-a20 file, I have adapted the tuto for my Bananapi Pro. Until this step, all is ok.

Did you read his updated post for 4.19.y? He mentioned that he had to create some .deb file because of the missing kernel-headers in the new kernel... Worth trying it?

 

Hi,

 

thank you for your answer, I try to install 

linux-dtb-next-sunxi_5.96_armhf.deb
linux-headers-next-sunxi_5.96_armhf.deb
linux-image-next-sunxi_5.96_armhf.deb
linux-u-boot-next-bananapipro_5.96_armhf.deb

 

but sadly nothing better.

Not simple...
