does not help I do not know @OrangePI:# dmesg | grep spi [ 1.756723] sunxi_spi_chan_cfg()1355 - [spi-0] has no spi_regulator. [ 1.767699] sunxi_spi_chan_cfg()1355 - [spi-1] has no spi_regulator.

tell me how to do it correctly all my attempts are unsuccessful generally disappears / dev / spidev i have orange pi one

HI what will happen if you change the FEX up to this type [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 = 1 spi_cs_bitmap = 1 spi_cs0 = port:PA13<2><1><default><default> spi_sclk = port:PA14<2><default><default><default> spi_mosi = port:PС00<2><default><default><default> spi_miso = port:PС01<2><default><default><default> [spi_devices] spi_dev_num = 2 will both devices work?

and can be /deb/devspi0.0 brought on board in this controller?

But you can find out If it is still possible to connect two readers on pin On which contacts: SCLK - 10pin SDA - 8pin MOSI - ? MISO - ? RST - pin 19, 21, 23, 24, 22 use first reader spi0 Where to connect and where to rule pyA20 or MFRC522 for RST-conact on reader

So where on the Orange PI One board we find PA15 and PA16 for the second reader Linux orangepione 3.4.113-sun8i # 16 SMP PREEMPT Tue Jun 13 14:15:57 CEST 2017 armv7l armv7l armv7l GNU / Linux @orangepione: # ls / dev / spi * /dev/spidev0.0 /dev/spidev1.0 leds_para leds_used = 0 Thank you
