How to start a sound&microphone on the Orange Pi Zero 2+ H3? root@orangepizeroplus2:/# aplay -l aplay: device_list:268: no soundcards found... root@orangepizeroplus2:~# uname -a Linux orangepizeroplus2 4.11.5-sun8i #3 SMP Thu Aug 3 08:36:37 CEST 2017 armv7l armv7l armv7l GNU/Linux root@orangepizeroplus2:~# lsmod Module Size Used by can_raw 16384 1 bluetooth 270336 0 qmi_wwan 24576 0 qcserial 16384 2 usb_wwan 16384 1 qcserial sun8i_codec_analog 24576 0 snd_soc_core 122880 1 sun8i_codec_analog snd_pcm_dmaengine 16384 1 snd_soc_core usbserial 32768 6 qcserial,usb_wwan snd_pcm 77824 2 snd_pcm_dmaengine,snd_soc_core sun8i_ths 16384 0 uio_pdrv_genirq 16384 0 cpufreq_dt 16384 0 uio 16384 1 uio_pdrv_genirq thermal_sys 57344 2 cpufreq_dt,sun8i_ths mcp251x 20480 0 can_dev 24576 1 mcp251x can 36864 1 can_raw usb_f_acm 16384 1 u_serial 20480 3 usb_f_acm g_serial 16384 0 libcomposite 40960 2 g_serial,usb_f_acm brcmfmac 172032 0 brcmutil 16384 1 brcmfmac cfg80211 204800 1 brcmfmac rfkill 24576 5 bluetooth,cfg80211

There was a new problem. The system worked with a flash drive. I transferred to internal memory. And orange stopped booting! If I disconnect the interrupt pin, orange is loaded ... In what there can be a problem, how it to win?

If you find the time, try different pins for interrupts, for me it is not entirely clear why it was PA2, but when connected to other pins, orange could not reboot

Everything worked! I tried various pins to interrupt and with PA2 worked without errors. Thank you all for the help!

After all the fixes, errors ceased to appear and the interface can0 appeared! Thank you! root@orangepizeroplus2:~# dmesg|grep mcp [ 8.873365] mcp251x spi1.0 can0: MCP2515 successfully initialized. root@orangepizeroplus2:~# dmesg|grep can [ 8.803670] can: controller area network core (rev 20120528 abi 9) [ 8.873365] mcp251x spi1.0 can0: MCP2515 successfully initialized. root@orangepizeroplus2:~# ifconfig -a can0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 NOARP MTU:16 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:10 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) I connected the interrupt pin to PA7, orange is loaded normally, but when I execute the reboot command, orange does not load. When the interrupt terminal is connected, the orange can not normally reboot. What can be done about this? If I disable the interrupt pin, the orange is loaded and the can-modules also. Next, I connect can0: Ip link set can0 up type can bitrate 250000 I try to forward the message: Cansend can0 100 # 43414e2054650000 I see this message on another device connected to another computer. But the re-sending does not work and command "candump can0" does not show anything either. Perhaps this is due to the disconnected interrupt pin. But when the output is connected it is not possible to restart the orange. In what here there can be a problem?

My connection with the module: 4 VCC 6 GND 19 - GPIO 15 - MOSI 21 - GPIO 16 - MISO 23 - GPIO 14 - CLK 24 - GPIO 13 - CS0 It's right? Is it necessary to connect a pin-INT on the module mcp2515, or without it to worked?

What pin should I choose?

Need help! I'm trying to connect the mcp2515 module to the Orange Pi Zero 2+ H3, but I can not. Dmesg wrote: [8.572220] mcp251x spi0.0: Can not initialize MCP2515. Wrong wiring?
