The error disappears and the SPI1 pins' mode set back to ALT4 when only "spi1-cs0-spidev" overlay is enabled. But if only "spi-sd" or both is enabled it set them back to "OFF" and the error appears.

now it looks like this:I replaced the target = <&spi1>; to target-path = </soc/spi@5011000>; because i got errors (Reference to non-existent node or label "spi1"). /dts-v1/; / { compatible = "allwinner,sun50i-h616"; fragment@0 { target-path = "/aliases"; __overlay__ { spi0 = "/soc/spi@5010000"; spi1 = "/soc/spi@5011000"; }; }; fragment@1 { target-path = "/soc/spi@5011000"; __overlay__ { spi1_pins: spi1-pins { pins = "PH6\0PH7\0PH8"; function = "spi1"; }; spi1_cs0_pin: spi1-cs0-pin { pins = "PH5"; function = "spi1"; }; }; }; fragment@2 { target-path = "/soc/spi@5011000"; __overlay__ { #address-cells = <0x01>; #size-cells = <0x00>; pinctrl-names = "default\0default"; pinctrl-0 = <&spi1_pins>, <&spi1_cs0_pin>; status = "okay"; mmc@0 { reg = <0x00>; compatible = "mmc-spi-slot"; voltage-ranges = <0xce4 0xce4>; spi-max-frequency = <0x2faf080>; status = "okay"; }; }; }; }; Now I could compile it without any error, but in /dev there is still only one mmcblk. root@orangepizero2w:allwinner/overlay # dmesg | grep -i 'spi' [ 1.415511] spi-nor spi0.0: ZB25VQ128A (16384 Kbytes) [ 24.548702] platform 5011000.spi: deferred probe pending

Like this? /dts-v1/; /plugin/; / { compatible = "allwinner,sun50i-h616"; fragment@0 { target-path = "/aliases"; __overlay__ { spi0 = "/soc/spi@5010000"; spi1 = "/soc/spi@5011000"; }; }; fragment@1 { target = <&spi1>; __overlay__ { spi1_pins: spi1-pins { pins = "PH6", "PH7", "PH8"; function = "spi1"; }; spi1_cs0_pin: spi1-cs0-pin { pins = "PH5"; function = "spi1"; }; }; }; fragment@2 { target = <&spi1>; __overlay__ { #address-cells = <1>; #size-cells = <0>; pinctrl-0 = <&spi1_pins>; pinctrl-names = "default", "default"; status = "okay"; mmc@0 { reg = <0>; compatible = "mmc-spi-slot"; voltage-ranges = <3300 3300>; spi-max-frequency = <50000000>; status = "okay"; }; }; }; };

I can't show you the physical connections because the orange pi is built into a custom board that I don't have access to right now, but the microSD module it connected to the SPI1-MOSI, -MISO, -CLK, -CS0 pins.

Hello, I have connected a microSD module to the SPI1 CS0 pins Is there a way to mount an SPI device? I tried, but I got this error: mount: /mnt/sdcard: /dev/spidev1.0 is not a block device. What is the best way to easily manage files on this secondary SD card?

Thanks, So I have an SD Card module connected to SPI1 (CS0) pins. root@orangepizero2w:~# dmesg | grep -i 'spi' [ 1.336073] sun50i-h616-pinctrl 300b000.pinctrl: pin-64 (5010000.spi) status -517 [ 1.336093] sun6i-spi 5010000.spi: Error applying setting, reverse things back [ 1.336368] sun50i-h616-pinctrl 300b000.pinctrl: pin-230 (5011000.spi) status -517 [ 1.336385] sun6i-spi 5011000.spi: Error applying setting, reverse things back [ 1.349503] spi-nor spi0.0: supply vdd not found, using dummy regulator [ 1.364641] spi-nor spi0.0: spi-nor-generic (16384 Kbytes) [ 234.215538] /dev/spidev1.0: Can't lookup blockdev spidev-test: root@orangepizero2w:/home/kvl/spidev-test# ./spidev_test -D /dev/spidev1.0 -v spi mode: 0x0 bits per word: 8 max speed: 500000 Hz (500 KHz) TX | FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF F0 0D | ......@....▒..................▒.

Yeah, I just realized that after the reinstall everything worked fine. Maybe I just messed up something before. Thank you for your help! Now I have another issue with SPI. Can I write here or should I open a new topic?

Well.. there was a little problem so i reinstalled the whole OS. Currently I only modified armbianEnv.txt. I added this line: overlays:i2c0 I also installed armbian-config and found i2c0-pi in System/Hardware so I enabled it. The device tree is currently unmodified so it has default configuration. Should I remove the PI7-8 from rgmii-pins and then change the i2c0-pins to "PI8\0PI7"? It has also a i2c0-pi-pins. Which one should I modify? i2c0-pi-pins { pins = "PI5\0PI6"; function = "i2c0"; phandle = <0x56>; }; i2c0-pins { pins = "PI6\0PI7"; function = "i2c0"; phandle = <0x1e>; };

Hi, How to enable i2c on PI8(SDA) and PI7(SCL)? I'm newbie in linux and not really understand what am I actually doing so I tried to make it with chatgpt but still not working. root@orangepizero2w:/# sudo i2cdetect -y 0 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- UU -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- It can't see any device, but there should be one on the 0x21.

I cannot receive data on serial port ttyS5. I able to write onto it, but the reading doesnt work. I'm using this https://github.com/officialdoniald/Xamarin.Android.SerialPort . I tried using adb shell commands like "cat < /dev/ttyS5" but there is no received data either. When I try to send data with "LibSerialPort.WriteLine("text")" I can see it in Hercules Terminal so the writing works. In Visual Studio Output there is this line: [c.SerialPortPoc] type=1400 audit(0.0:532): avc: denied { read write } for name="ttyS5" dev="tmpfs" ino=2487 scontext=u:r:untrusted_app_27:s0:c512,c768 tcontext=u:object_r:serial_device:s0 tclass=chr_file permissive=1 app=SerialPortPoc.SerialPortPoc Device: Orange Pi Zero 2, Android 10
