Enable Raspberry Pi 4B SPI GPIO Interface
it is easy to enable the SPI interface in Emteria OS 7.6 on Rasp 3 B+. Just add "dtparam=spi=on" in config.txt.
I try the same approach in Emteria OS 13.3 on Rasp 4. It does not work.
Does anybody known, if SPI is supported on Rasp 4 ? If yes, how to Enable it ?
Thanks a lot in advance !
