I was using Linux 5.11 vanilla dts (from Torvalds' github) for NanoPi M4V2 and using that as base for my custom dts without overlays. Also u-boot was built (and patched) by me - learning new things and so on My idea was to share my experience in hope if someone decided to do something similar, but this is Armbian forum where people are using Armbian stuff without compiling their own so... Now I have reinstalled fresh Armbian for NanoPC T4 (u-boot, kernel and ramdisk are on SD card, rootfs is on NVMe but it shouldn't matter). Image I dd-ed to SD card (from 12.06.2021.): https://mirrors.netix.net/armbian/dl/nanopct4/archive/Armbian_21.05.1_Nanopct4_focal_current_5.10.35_xfce_desktop.img.xz NVMe doesn't work in u-boot (works in Linux) for my board but that's another topic I am using Armbian u-boot with /boot/dtb/rockchip/rk3399-nanopc-t4.dtb. After dts overlay I have sound on my SoM-RK3399v2 (which should be pretty similar to T4). # dmesg | grep rt5651 [ 5.727048] rt5651 1-001a: Failed to reguest IRQ 0: -22 # uname -a Linux miki 5.10.35-rockchip64 #21.05.1 SMP PREEMPT Fri May 7 13:53:11 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux # grep -E "SND_SOC_ROCKCHIP_I2S|SND_SOC_RT5651" /boot/config-5* CONFIG_SND_SOC_ROCKCHIP_I2S=m CONFIG_SND_SOC_ROCKCHIP_I2S_TDM=m CONFIG_SND_SOC_RT5651=m # i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- UU -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- # cat /etc/modules <empty> # lsmod | grep snd snd_soc_hdmi_codec 20480 1 snd_soc_simple_card 24576 3 snd_soc_simple_card_utils 28672 1 snd_soc_simple_card snd_soc_rt5651 98304 1 snd_soc_rl6231 20480 1 snd_soc_rt5651 snd_soc_rockchip_spdif 16384 0 snd_soc_rockchip_i2s 24576 4 snd_soc_core 237568 6 snd_soc_rt5651,snd_soc_hdmi_codec,snd_soc_rockchip_spdif,snd_soc_simple_card_utils,snd_soc_rockchip_i2s,snd_soc_simple_card snd_pcm_dmaengine 20480 1 snd_soc_core snd_pcm 118784 4 snd_soc_rt5651,snd_soc_hdmi_codec,snd_soc_core,snd_pcm_dmaengine snd_timer 40960 1 snd_pcm snd 90112 10 snd_soc_hdmi_codec,snd_timer,snd_soc_core,snd_pcm soundcore 16384 1 snd # aplay -l **** List of PLAYBACK Hardware Devices **** Invalid MIT-MAGIC-COOKIE-1 keyxcb_connection_has_error() returned true card 0: realtekrt5651co [realtek,rt5651-codec], device 0: ff890000.i2s-rt5651-aif1 rt5651-aif1-0 [ff890000.i2s-rt5651-aif1 rt5651-aif1-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: hdmisound [hdmi-sound], device 0: ff8a0000.i2s-i2s-hifi i2s-hifi-0 [ff8a0000.i2s-i2s-hifi i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 # cat /etc/asound.conf <empty> # cat /proc/asound/pcm 00-00: ff890000.i2s-rt5651-aif1 rt5651-aif1-0 : ff890000.i2s-rt5651-aif1 rt5651-aif1-0 : playback 1 : capture 1 01-00: ff8a0000.i2s-i2s-hifi i2s-hifi-0 : ff8a0000.i2s-i2s-hifi i2s-hifi-0 : playback 1 # cat /sys/kernel/debug/clk/clk_i2sout_src/clk_parent clk_i2s1 # dpkg -l | grep -v ^rc | grep -E "linux-dtb-|linux-image-" ii linux-dtb-current-rockchip64 21.05.1 arm64 Linux DTB, version 5.10.35-rockchip64 ii linux-image-current-rockchip64 21.05.1 arm64 Linux kernel, version 5.10.35-rockchip64 # grep -iE "name|linux|version" /etc/armbian-release BOARD_NAME="NanoPC T4" DISTRIBUTION_CODENAME=focal VERSION=21.05.2 LINUXFAMILY=rockchip64 I still have these messages in syslog but sound works nonetheless: Jun 13 21:28:31 miki kernel: [ 28.822975] rockchip-i2s ff8a0000.i2s: Fail to set mclk -22 Jun 13 21:28:31 miki kernel: [ 28.823485] rockchip-i2s ff8a0000.i2s: ASoC: error at snd_soc_dai_set_sysclk on ff8a0000.i2s: -22 Jun 13 21:39:50 miki kernel: [ 708.376058] rockchip-i2s ff890000.i2s: Fail to set mclk -22 Jun 13 21:39:50 miki kernel: [ 708.376576] rockchip-i2s ff890000.i2s: ASoC: error at snd_soc_dai_set_sysclk on ff890000.i2s: -22 This is overlay which I have used: #include <dt-bindings/pinctrl/rockchip.h> #include <dt-bindings/gpio/gpio.h> #include <dt-bindings/clock/rk3399-cru.h> /dts-v1/; /plugin/; / { compatible = "rockchip,rk3399"; fragment@0 { target = <&rt5651>; __overlay__ { status = "okay"; }; }; fragment@1 { target = <&i2s1>; __overlay__ { assigned-clocks = <&cru SCLK_I2SOUT_SRC>; assigned-clock-parents = <&cru SCLK_I2S1_8CH>; pinctrl-0 = <&i2s_8ch_mclk>,<&i2s1_2ch_bus>; status = "okay"; }; }; fragment@2 { target = <&pinctrl>; __overlay__ { i2s1 { i2s_8ch_mclk: i2s-8ch-mclk { // GPIO4_A0 - RK3399 I2S_CLK rockchip,pins = <4 RK_PA0 1 &pcfg_pull_none>; }; }; headphone { hp_det: hp-det { // GPIO4_D4 - HP_DET_H pin on SoM-RK3399v2 rockchip,pins = <4 RK_PD4 RK_FUNC_GPIO &pcfg_pull_up>; }; }; }; }; };

I was in similar situation but on other board similar to T4.

To Linux kernel boot argument add "video=eDP-1:1920x1080@60" and remove other "video=HDMI..." parts. I changed mine bootargs in GRUB but similar can be achieved in uboot. Didn't try X11 with it and I didn't manage to get early boot messages on eDP panel (yet). But after booting I get login prompt and I can login on it. Linux 5.10.12 (linux-image-current-rockchip64 on Armbian 21.02).

I am trying to enable sound with RT5651 audio codec on SoM-RK3399v2. Hardware is integrated on the board (on i2c1 bus, address 0x1a), worked with official FriendlyElec Linux (4.4 kernel IIRC) and tests were run with powered speakers (which work when connected to PC). I used this patch to patch my current device tree: https://github.com/armbian/build/blob/master/patch/kernel/rockchip64-dev/board-nanopi-m4v2-dts-add-sound-card.patch I did not use Kconfig file from the patch as it seems that my kernel have has built that modules. page 19 of NanoPI M4V2 and page 7 of SoM-RK3399 schematic shows that same audio codec (rt5651 on the same busses (I2S1 and I2C1) is used on both boards): https://wiki.friendlyarm.com/wiki/images/c/cc/NanoPi-M4V2_1908_Schematic.pdf https://wiki.friendlyarm.com/wiki/images/d/de/SOM-RK3399_Dev_Kit_1904_Schematic.pdf After reboot I can see card but it didn't play any sound on the speakers (except random quite noises - which also occures in u-boot) # dmesg | grep rt5651 [ 3.535527] rt5651 1-001a: Failed to reguest IRQ 0: -22 # uname -a Linux miki 5.10.12-rockchip64 #21.02.1 SMP PREEMPT Wed Feb 3 20:55:02 CET 2021 aarch64 aarch64 aarch64 GNU/Linux # grep -E "SND_SOC_ROCKCHIP_I2S|SND_SOC_RT5651" /boot/config-5.10.12-rockchip64 CONFIG_SND_SOC_ROCKCHIP_I2S=m CONFIG_SND_SOC_ROCKCHIP_I2S_TDM=m CONFIG_SND_SOC_RT5651=m # i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- UU -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- # cat /etc/modules snd_soc_simple_card snd_soc_rt5651 # lsmod | grep snd snd_soc_hdmi_codec 20480 1 snd_soc_rockchip_spdif 16384 0 snd_soc_rockchip_i2s 24576 4 snd_soc_rt5651 98304 1 snd_soc_rl6231 20480 1 snd_soc_rt5651 snd_soc_simple_card 24576 0 snd_soc_simple_card_utils 28672 1 snd_soc_simple_card snd_soc_core 237568 6 snd_soc_rt5651,snd_soc_hdmi_codec,snd_soc_rockchip_spdif,snd_soc_simple_card_utils,snd_soc_rockchip_i2s,snd_soc_simple_card snd_pcm_dmaengine 20480 1 snd_soc_core snd_pcm 118784 4 snd_soc_rt5651,snd_soc_hdmi_codec,snd_soc_core,snd_pcm_dmaengine snd_seq_midi 20480 0 snd_seq_midi_event 16384 1 snd_seq_midi snd_rawmidi 40960 1 snd_seq_midi snd_seq 81920 2 snd_seq_midi,snd_seq_midi_event snd_seq_device 20480 3 snd_seq,snd_seq_midi,snd_rawmidi snd_timer 40960 2 snd_seq,snd_pcm snd 90112 7 snd_seq,snd_seq_device,snd_soc_hdmi_codec,snd_timer,snd_soc_core,snd_pcm,snd_rawmidi soundcore 16384 1 snd # aplay -l **** List of PLAYBACK Hardware Devices **** xcb_connection_has_error() returned true card 0: realtekrt5651co [realtek,rt5651-codec], device 0: ff890000.i2s-rt5651-aif1 rt5651-aif1-0 [ff890000.i2s-rt5651-aif1 rt5651-aif1-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: hdmisound [hdmi-sound], device 0: ff8a0000.i2s-i2s-hifi i2s-hifi-0 [ff8a0000.i2s-i2s-hifi i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 # cat /etc/asound.conf pcm.!default { type hw card 0 device 0 } ctl.!default { type hw card 0 } # cat /proc/asound/pcm 00-00: ff890000.i2s-rt5651-aif1 rt5651-aif1-0 : ff890000.i2s-rt5651-aif1 rt5651-aif1-0 : playback 1 : capture 1 01-00: ff8a0000.i2s-i2s-hifi i2s-hifi-0 : ff8a0000.i2s-i2s-hifi i2s-hifi-0 : playback 1 mpv reports no errors, but there is no sound.

Any ideas what might be the problem?

Finally found the problem - HW "issue". My SPI flash is not soldered (no place on motherboard) - it is connected with wires which are (presumably) too long. Workaround is to reduce SPI speed in u-boot and Linux. U-boot: diff --git a/arch/arm/dts/rk3399-rockpro64.dtsi b/arch/arm/dts/rk3399-rockpro64.dtsi index 9bca258012..797dd80d38 100644 --- a/arch/arm/dts/rk3399-rockpro64.dtsi +++ b/arch/arm/dts/rk3399-rockpro64.dtsi @@ -677,7 +677,7 @@ flash@0 { compatible = "jedec,spi-nor"; reg = <0>; - spi-max-frequency = <10000000>; + spi-max-frequency = <1000000>; }; }; Linux: Recompile your device tree with reduced SPI speed: flash@0 { compatible = "jedec,spi-nor"; reg = <0>; - spi-max-frequency = <10000000>; + spi-max-frequency = <1000000>; };

According to this, to run u-boot from flash I just need latest u-boot, apply patch from the link (CONFIG_SF_DEFAULT_BUS=1), copy config to .config, build it, flash it to SPI and it should work? I did that and for my SOM-RK3399v2 (I have added SPI flash 16 MB chip to it), it starts to boot and it got stuck on line: Trying to boot from SPI I am trying for weeks, tried various .configs/OFFSets/various config options/printf debugging/... , various binary files (for RockPro64, PineBook Pro, Roc-PC, etc) and same error. U-boot flashed to SD/eMMC works. SPI flash works in Linux:
