Hello.
I need help with SPI and si4463 radio.

si4463 radio works great on Arduino Pro Mini.
FreeBSD 12.2 (armv7 r369379) on NanoPi NEO no not work with it.
MISO always has the HIGH state.
The logical analyser says that values of CLK, MOSI, CS is identical to Arduino.
The only difference is that interval between CS and CLK is much bigger on FreeBSD.

By the way BMP280 works fine on FreeBSD.

What do you think I can be done for si4463?
Maybe there are some additional settings for SPI?
