  1. I tried sound@1 { compatible = "allwinner,sunxi-daudio0-machine"; sunxi,daudio0-controller = <0x4e>; status = "okay" device_type = "snddaudio0"; }; and also changed the status to "okay" on below entry. daudio@0x01c22000 { compatible = "allwinner,sunxi-daudio"; reg = <0x0 0x1c22000 0x0 0x58>; clocks = <0x2 0x42>; pinctrl-names = "default", "sleep"; pinctrl-0 = <0x43>; pinctrl-1 = <0x44>; pcm_lrck_period = <0x20>; pcm_lrckr_period = <0x1>; slot_width_select = <0x20>; pcm_lsb_first = <0x0>; tx_data_mode = <0x0>; rx_data_mode = <0x0>; daudio_master = <0x4>; audio_format = <0x1>; signal_inversion = <0x1>; frametype = <0x0>; tdm_config = <0x1>; tdm_num = <0x0>; status = "okay"; linux,phandle = <0x4e>; phandle = <0x4e>; device_type = "daudio0"; }; Even with this changes I2S at Euler pin is not working. Does anyone tried testing I2S on Euler bus pin with kernel 3.10.107 ?
  2. I am using an armbian build image on PINE A64+ board with the kernel 3.10.107. During build i enabled below I2S driver as built-in. CONFIG_SND_SOC_SUNXI_RW=y CONFIG_SND_SOC_SUNXI_AUDIO_DMA=y CONFIG_SND_SOC_SUNXI_TDM=y CONFIG_SND_SUNXI_SOC=y CONFIG_SND_SOC_INTERNAL_AUDIOCODEC=y CONFIG_SND_SOC_INTERNAL_I2S=y CONFIG_SND_SOC_AUDIO_CODEC_MACHINE=y CONFIG_SND_SOC_DAUDIO_PLATFORM=y CONFIG_SND_SOC_VIRCODEC=y CONFIG_SND_SOC_DAUDIO0_MACHINE=y # CONFIG_SND_SOC_DAUDIO1_MACHINE is not set CONFIG_SND_SUNXI_SOC_HDMIAUDIO=y The Internal Audio and HDMI Audio are initialized successfully but failed to snddaudio0 which can be accessed from Euler bus pins. below is the error log.

Please help me to enable I2S codec testing on Euler bus I2S pins using Armbian build image. Regards Ranjit
  3. No, I did not install DTB package. Could you please let me know where can I find that matching DTP package. I don't see it in the output folder of the build directory.
  4. Hi, thanks for the comment. I tried to install image as you mentioned. However the device doesn't boot and stops with following messages. Found legacy kernel configuration ** File not found /boot/script.bin ** Image Name: uInitrd Image Type: ARM Linux RAMDisk Image (gzip compressed) Data Size: 7507703 Bytes = 7.2 MiB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum … OK Loading Ramdisk to 498d7000, end 49fffef7 … OK Starting Kernel ... I wanted to test external audio codec on I2S pin of BPI M2+ which seems cannot be configured to use with Armbian download image. In order to do any BSP level changes, i have to build the kernel. Any help will be highly appreciated.
  5. Hi, I am new to the Armbian. I have build the kernel for BananaPi M2+ using the instruction specified in Armbian document for Building with Vagrant. I could see the output file "linux-image-sun8i-5.59.armhf.deb" in the "output/debs" folder. Know I don't know how to download or install this file on the SD card which is running on my bananaPi M2+. Bascically I need guidance on how to transfer my kernel build image from my windows PC to the SD card which I will be using to test the Bananapi M2+ board. Any help or documents will be highly appreciated.
