I solved the problem myself. Armbian images are perfect!
The problem was that I tried to use /dev/spidev0.0, but the first available is /dev/spidev1.0,
contrary to the i2c which is /dev/i2c-0.
So the right parameter is param_spidev_spi_bus=1 ... with /dev/spidev1.0 things work great!
I am very sorry for disturbing the community ... I had to be more careful!
Friendliness to all.
