[Info] FriendlyARM PCM5102A-Hat with NanoPi Neo under mainline 4.x.x and dev 5.3.3


Recommended Posts

I did that on a NanoPi Neo with the FriendlyARM PCM5102A Hat

https://www.friendlyarm.com/index.php?route=product/product&product_id=169 )
using kernel 4.14.87-sunxi and armbian 5.67 (or later would be only 5.65?)
(before that I did use legacy kernel 3.4.x with the PCM510A)


and the armbian-BuildSystem

plus (THANKS to) informations in threads from  @dony71 , @Christos, @Valery Rezvyakov
and the the Reference-Threads you could find above :)

!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ATTENTION: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
After reboot my NanoPi Neo show the following armbian-version:
ARMBIAN 5.65 stable Debian GNU/Linux 9 (stretch) 4.14.84-sunxi
and 2 upgrades for headers&image (without the PCM5102A support)

please keep in mind to freeze the kernel-updates in armbian-config
for not to loose the support (module) for the PCM5120A!

Yesterday I did read on twitter about a new 4.19.y armbian for the Neo - so I did try that with my PCM5102A-Hat:
 

Quote

Added polished, minimal and top performant #Bionic or #Stretch based images with optimised @linuxfoundation K4.19.y, @armbian hardware configurator and @armbian software installer for @AllwinnerTech #H3 powered #nanopineo https://www.armbian.com/nanopi-neo

 

I did try it like in my instructions above in this thread, but failed (again) with the armbian-add-overlay part.

armbian-add-overlay told me that it cant compile a overlay-dts.

I did found the information that this is because of the missing kernel-headers - the older dtc did told this "secret".

 

OK - I did try to install the kernel-headers via armbian-config -> software, BUT this will not install the kernel-headers for the current kernel-version :(

It will only install the latest available as kernel-header-package.

 

Latest available was 4.14.87 and I did use the new "next" 4.19

 

So I had to use at first the armbian-build-system to create the following .deb's for me :
 

-rw-r--r-- 1 root root   173380 Jan 11 21:43 linux-dtb-next-sunxi_5.70_armhf.deb
-rw-r--r-- 1 root root 10608812 Jan 11 21:43 linux-headers-next-sunxi_5.70_armhf.deb
-rw-r--r-- 1 root root 19933808 Jan 11 21:43 linux-image-next-sunxi_5.70_armhf.deb
-rw-r--r-- 1 root root   171212 Jan 11 20:39 linux-u-boot-next-nanopineo_5.70_armhf.deb

While editing the Kconfig file I did see the name/path has changed

from 

/home/guido/build/cache/sources/linux-mainline/linux-4.14.y/sound/soc/codecs/Kconfig

to 

/home/guido/build/cache/sources/linux-mainline/orange-pi-4.19/sound/soc/codecs/Kconfig

but there was nothing to change because it was already
[EDIT] there was nothing to change, because it was the 2nd compile and the patch was created at the 1st compile.

 

( @dony71 did you also see that there isnt to change anything? I am not sure about the menu-driven screen after selecting m for Module,
  but it did work and create the module)

config SND_SOC_PCM5102A
    tristate "Texas Instruments PCM5102A CODEC - I2S"

 

After installing the .deb's I hadnt no problem anymore with armbian-add-overlay - because now I had the right kernel-headers for my kernel :)

 

Later I converted the .dtb to .dts, edited the .dts and converted it back to .dtb

 

Now the PCM5102A-Hat is running under

ARMBIAN 5.69 stable Debian GNU/Linux 9 (stretch) 4.19.13-sunxi

Linux npi-neo 4.19.13-sunxi #5.70 SMP Fri Jan 11 21:40:58 +03 2019 armv7l GNU/Linux

Around  8 months later I did test my instructions with my NanoPi Neo and 

Debian Buster with Armbian Linux 5.3.3-sunxi <== dev-version
package bsp-kernel[5.98] u-boot[5.98] dtb[5.98] firmware[5.98] config[5.98]

 

Some changes:

 

1.) in the actual armbian-build-system there is no more a ./build/config-default.conf

now you have (after backuping the file) to fill in the content of the attached config-example.conf
to ./build/userpatches/config-example.conf


On my mind I recall there is a symbolic link from ./build/userpatches/config-default.conf
to ./build/userpatches/config-example.conf - so I edited this file ;)

 

2.) for the actual Armbian Linux 5.3.3-sunxi <== dev-version
you have to edit /home/guido/build/cache/sources/linux-mainline/orange-pi-5.3/sound/soc/codecs/Kconfig
( former filenames: 

/home/guido/build/cache/sources/linux-mainline/linux-4.14.y/sound/soc/codecs/Kconfig   OR

/home/guido/build/cache/sources/linux-mainline/orange-pi-4.19/sound/soc/codecs/Kconfig )
 

from

config SND_SOC_PCM5102A
        tristate

to

config SND_SOC_PCM5102A
        tristate "Texas Instruments PCM5102A CODEC - I2S"

 

gentle reminder: (because I missed it again while compiling  and had to compile 3 times :( )

when asked about compiling the PCM5102A module press m

Texas Instruments PCM5102A CODEC - I2S (SND_SOC_PCM5102A) [N/m/?] (NEW) m = m for module compilation

 

But with these changes it also does work with kernel 5.3.3 armbian dev debian buster :)

@guidol should we have an I2S overlay for the H3 boards?  I don't see why not...

Yes ;) a working overlay would be fine if there is also support included for the 5102A in the kernel :)

 

see
 

config SND_SOC_PCM5102A
        tristate "Texas Instruments PCM5102A CODEC - I2S"

Today I tested volumio ( https://volumio.org/ )

The audiophile music player designed and
fine-tuned for high quality music playback.

on a x86-system and a Raspberry Pi3 and on a webpage I did read that a PCM5102A DAC can be used with the Raspberry Pi (40 Pin header) as a HiFiBerry-DAC.

So I searched how to connect the FriendlyARM (Neo) PCM5102A-Hat to the Raspberry 40-pin header:

I  want a digital music player base on NanoPi NEO,  with device PCM5102A I2S sound card build.

here is my pross: 

1: Kernel: uname -a
Linux nanopineo 5.8.14-sunxi #trunk SMP Sun Oct 11 18:51:16 CST 2020 armv7l armv7l armv7l GNU/Linux

 

2: build u-boot and kernel with armbian--build , and It is passed, so wirite the IMG file to sd card!.

 

3: I use command dtc to conver dtb to source, and chang I2S, SPI0, IR0,CODEC
i2s@1c22000 ---->okay
codec@1c22c00 --->okay
spi@1c68000 --->okay
ir@1f02000 --->okay

the soundcard H3 Audio Codec is only the "normal" analog audio device - not a I2S-audio device.
 

I also got since 5.8.x kernels the problem with a NanoPi A64 that 

1c22c00.codec mapping ok

but I cant get any sound out of the I2S-audio-device.

 

I think its not only a NanoPi Neo problem :( - but when the I2S device like

Karte 1: I2Smaster [I2S-master], Gerät 0: 1c22000.i2s-pcm5102a-hifi pcm5102a-hifi-0 []

doenst show up - then there is another problem in your .dtb/.dts :(

@spender

PCM5102A-Test with Raspberry did end here ;) - so I could test my instructions with armbian buster and Kernel 5.9.0

again on the NanoPi Neo :) 

 

I had only to

- enable (from disabled to okay) i2s@1c22000 in .dtb (decomple and compile)

decompile:
dtc -I dtb -O dts /boot/dtb/sun8i-h3-nanopi-neo.dtb -o /boot/dtb/sun8i-h3-nanopi-neo.dts

compile:
dtc -I dts -O dtb /boot/dtb/sun8i-h3-nanopi-neo.dts -o /boot/dtb/sun8i-h3-nanopi-neo.dtb

 

- build / addoverlay (  armbian-add-overlay ./sun8i-h3-I2S-out.dts )

- create /etc/asound.conf
[EDIT]
- apt-mark hold linux-dtb-dev-sunxi

- reboot

 

and it works again very well:

According to the method you introduced, the music played happily. thank you very much.  Good good study, day day UP.

@spender for not loosing the .dtb-change (disabled to okay) you also have to set the dtb-package on hold
(here armbian dev example):

apt-mark hold linux-dtb-dev-sunxi
linux-dtb-dev-sunxi auf Halten gesetzt.

apt-mark showhold
linux-dtb-dev-sunxi

if you are not using dev you could find your dtb-packe with the following command:
root@npi-neo-25(192.168.6.25):~# dpkg -l|grep dtb
linux-dtb-dev-sunxi		20.08.11	armhf	Linux DTB, version 5.9.0-sunxi

Thanks again! There is a new knowledge point! Identified as not modifying dtb.
Now I am trying to add an ILI9341 screen to IT. Since the new kernel no longer supports fbtft_device.ko, it is modified to be defined by DT in dtb. I don't know yet. I am learning how to learn overlay to revise, just like this pcm5102a. If you don’t understand, try to add it yourself. If it is really unclear, I will post for help! enjoy working!

Sorry - Iam not a big specialist in dtb-files. So I cant help you with the display :( 

It could be very difficult/impossible to support the display via dtb when the kernel doenst support it.
But as I remember reading teh forum you did aleready got a own thread for the display (or was it another member of the form)?:
