I am fully recompiled all Omega firmware, now my kernel have all spi drivers:
root@Omega-3079:/# lsmod | grep spi
regmap_spi 1274 0
spi_bitbang 2661 1 spi_gpio
spi_gpio 5424 0
spidev 6336 0
I also successfully compiled driver spi-gpio-driver-master using some additional required files from firmware sources. For example, onion-debug.h was found in i2c-exp-driver, etc.
After spi-gpio-driver-master compile I have spi-tool utility, libonionspi.so and python onionSpi.so module.
But I don't see soft-spi device in /dev:
root@Omega-3079:~# ls -l /dev/spi*
crw------- 1 root root 153, 0 Dec 6 16:29 /dev/spidev0.1
/dev/spidev0.1 -- hardware SPI, used python3-spidev driver.
But spi-tool utility, libonionspi.so and python onionSpi.so used /dev/spidev%d.%d device too.
As I think spi_gpio driver should create some other device in /dev. May be I should run some "activate procedure" for spi_gpio kernel driver?
Or https://github.com/OnionIoT/spi-gpio-driver too old and it cannot work with some latest Omega's Linux kernels?
dmesg outputs only hardware /dev/spidev0.1:
root@Omega-3079:/# dmesg | grep spi
