Hi, How i can find information for set the fex file, kernel, etc. etc. for use the spi in userspace? root@orangepipc:~# uname -a Linux orangepipc 4.10.0-sun8i #5 SMP Tue Feb 14 02:53:01 CET 2017 armv7l armv7l armv7l GNU/Linux root@orangepipc:~# lsmod Module Size Used by sun4i_codec 28243 3 rt2800usb 16226 0 sun8i_codec_analog 13766 1 rt2800lib 57122 1 rt2800usb snd_soc_core 115473 2 sun4i_codec,sun8i_codec_analog snd_pcm_dmaengine 4221 1 snd_soc_core rt2x00usb 9245 1 rt2800usb rt2x00lib 34437 3 rt2800lib,rt2800usb,rt2x00usb mac80211 324953 3 rt2800lib,rt2x00lib,rt2x00usb snd_pcm 70145 2 snd_pcm_dmaengine,snd_soc_core input_leds 2724 0 ir_lirc_codec 4630 0 evdev 9979 0 cfg80211 192770 2 rt2x00lib,mac80211 lirc_dev 8351 1 ir_lirc_codec rfkill 10928 3 cfg80211 sunxi_cir 3825 0 sun8i_ths 3134 0 cpufreq_dt 3522 0 thermal_sys 43232 2 cpufreq_dt,sun8i_ths uio_pdrv_genirq 3354 0 uio 8012 1 uio_pdrv_genirq gpio_keys 8517 0 spidev 6382 0 uas 11678 0 orangepipc.fex [spi0] spi_used = 1 spi_cs_bitmap = 1 spi_mosi = port:PC00<3><default><default><default> spi_miso = port:PC01<3><default><default><default> spi_sclk = port:PC02<3><default><default><default> spi_cs0 = port:PC03<3><1><default><default> [spi1] spi_used = 0 spi_cs_bitmap = 1 spi_cs0 = port:PA13<2><1><default><default> spi_sclk = port:PA14<2><default><default><default> spi_mosi = port:PA15<2><default><default><default> spi_miso = port:PA16<2><default><default><default> [spi_devices] spi_dev_num = 1 [spi_board0] modalias = "spidev" max_speed_hz = 33000000 bus_num = 0 chip_select = 0 mode = 0 full_duplex = 1 manual_cs = 0 root@orangepipc:~# ls /dev/spi* ls: cannot access '/dev/spi*': No such file or directory i don't see in /dev any spidevx.0 device armbianmonitor -u ------------- http://sprunge.us/OCaP
