Hi! I am newbie in Linux.
I booted raspbian on OrangePi zero and don't found /dev/spidevX.X to use SPI.
Dmesg shows me following:

  1. [ 0.469611] sunxi_spi_chan_cfg()1376 - [spi-0] has no spi_regulator.
  2. [ 0.469803] sunxi_spi_chan_cfg()1376 - [spi-1] has no spi_regulator.
Copy code

After little Google browsing I found this:
Fex_Guide and SPIdev
I tried to put following in /boot/config.txt file:

  1. [spi0_para]
  2. spi_used = 1
  3. spi_cs_bitmap = 1
  4. spi_cs0 = port:PI10<2><default><default><default>
  5. spi_sclk = port:PI11<2><default><default><default>
  6. spi_mosi = port:PI12<2><default><default><default>
  7. spi_miso = port:PI13<2><default><default><default>

  8. [spi_devices]
  9. spi_dev_num = 1

  10. [spi_board0]
  11. modalias = "spidev"
  12. max_speed_hz = 12000000
  13. bus_num = 0
  14. chip_select = 0
  15. mode = 0
  16. full_duplex = 1
  17. manual_cs = 0
Copy code


After rebooting the board I don't see spidevs in /dev directory.
Dmesg also doesn't shown me any changes. Does this mean that I need to build linux kernel from sources
or I did something wrong?

Can't use armbian because there are a lot of Raspbian libraries need to be used.

As explained here:
http://www.orangepi.org/Docs/FAQ.html
  1. sudo modprobe spi-sun7i
Copy code

not works:
  1. modprobe: ERROR: ../libkmod/libkmod.c:557 kmod_search_moddep() could not open moddep file '/lib/modules/3.4.39/modules.dep.bin'
Copy code

... but it looks like they don't work? Raspbian for Orange pi is just some old Raspbian+extremly old and unsupported kernel for Allwinner H3 ... which is completely different than RPi.
