guidol Posted January 12, 2019 Author Posted January 12, 2019 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 dmesg|grep -i i2s [ 8.524723] asoc-simple-card sound_i2s: pcm5102a-hifi <-> 1c22000.i2s mapping ok aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Codec [H3 Audio Codec], device 0: CDC PCM Codec-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: I2Smaster [I2S-master], device 0: 1c22000.i2s-pcm5102a-hifi pcm5102a-hifi-0 [] Subdevices: 0/1 Subdevice #0: subdevice #0 FOR SURE: I did freeze the kernel/updates in armbian-config to keep my PCM5102A working after updating in the future 0 Quote

le51 Posted December 15, 2019 Posted December 15, 2019 I've made a breakout board. The small white IC, is an optocoupler and the non connected cables are for a midi in (but not yet finished) interface. From this breakout board, I will also connect the RCA cinch out. Final goal is to run a zynthian synth on armbian (see https://zynthian.org/) 2 Quote
TonyMac32 Posted January 7, 2020 Posted January 7, 2020 @guidol should we have an I2S overlay for the H3 boards? I don't see why not... Also, for the K1 Plus, the Pimoroni PHAT DAC should work if you just need the DAC. 0 Quote

[ 3.632908] sun4i-codec 1c22c00.codec: Codec <-> 1c22c00.codec mapping ok [ 11.555242] cedrus 1c0e000.video-codec: Device registered as /dev/video0 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 0 Quote
spender Posted October 16, 2020 Posted October 16, 2020 I2S seems to be no problem in the old version of armbian. So I am going to downgrade the version. The question now is how to compile the lower version? All scripts are defined as downloading the latest version. too hard. The attachment is the current device tree definition. sun8i-h3-nanopi-neo_OK-IR-I2S-SPI0.dts 0 Quote

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 0 Quote
spender Posted October 18, 2020 Posted October 18, 2020 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! 0 Quote

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)?: 0 Quote
guidol Posted December 17, 2020 Author Posted December 17, 2020 change of .dtb (activating 1c22000) & creating overlay (armbian-add-overlay ./sun8i-h3-I2S-out.dts) does also work on uname -a Linux npi-neo-25 5.10.0-sunxi #trunk SMP Wed Dec 16 17:45:03 +03 2020 armv7l GNU/Linux package bsp-kernel[21.02.0-trunk] u-boot[21.02.0-trunk] dtb [21.02.0-trunk] firmware [21.02.0-trunk] config[21.02.0-trunk] branch[dev] like before on kernel 5.9.0 1 Quote
MichaIng Posted February 5, 2022 Posted February 5, 2022 Instead of manipulating the main device tree, enabling i2s@1c22000 should be possible via overlay as well, like: fragment@0 { target-path = "/soc/i2s@1c22000"; __overlay__ { status = "okay"; }; }; Hence the whole overlay: /dts-v1/; /plugin/; / { compatible = "allwinner,sun8i-h3"; fragment@0 { target-path = "/soc/i2s@1c22000"; __overlay__ { status = "okay"; }; }; fragment@1 { target-path = "/"; __overlay__ { pcm5102a: pcm5102a { #sound-dai-cells = <0>; compatible = "ti,pcm5102a"; pcm510x,format = "i2s"; }; }; }; fragment@2 { target = <&i2s0>; __overlay__ { status = "okay"; pinctrl-0 = <&i2s0_pins>; sound-dai = <&pcm5102a>; pinctrl-names = "default"; }; }; fragment@3 { target-path = "/"; __overlay__ { sound_i2s { compatible = "simple-audio-card"; simple-audio-card,name = "I2S-master"; simple-audio-card,mclk-fs = <256>; simple-audio-card,format = "i2s"; status = "okay"; simple-audio-card,cpu { sound-dai = <&i2s0>; }; simple-audio-card,codec { sound-dai = <&pcm5102a>; }; }; }; }; }; I will verify that the path /soc/i2s@1c22000 is correct, I guess there is a symbol for this as well, but obviously it is not <&i2s0>. 2 Quote
Nefedorov Posted December 14, 2022 Posted December 14, 2022 Good afternoon dear Gurus! I have a Nano Pe Neo Armbian board. It turned out to output sound to the 5102 chip using your theme. The question arose how can I output sound in TDM format. I use the ADAU1452 chip, but I think that this is not important. As I understand it, you need to correctly register the overlay. but I'm confused. can you please. if it's not difficult, explain how to correctly register the audio settings file for alsa so that I have 4 sound cards in tdm format to output armbian. thank you very much. Posted in the wrong thread last time. I'm sorry 0 Quote
guidol Posted December 14, 2022 Author Posted December 14, 2022 @Nefedorov Sorry - I have no clue about it. For the 5102 I corrected the .DTBs with some other user to make it work. I have no idea abot TDM and how to use 4 soundcards at once 0 Quote
Nefedorov Posted December 14, 2022 Posted December 14, 2022 I may not have written correctly, I would like to transmit several channels on the i2s bus at the same time 6 pcs. As I understand it, you can take any chip that supports multichannel transmission such as front left, right, rear, left right and centre and subwoofer. These chips should just use the method not left justify but tdm 0 Quote
