Hello friends!

I use Orange Pi Zero Plus (H5) with OS Armbian_20.11.7_Orangepizeroplus_buster_current_5.10.4 - on new versions of the distribution kit SPI does not turn on at all!
I connect to pin 19 (SPI1_MOSI, PA15) DI WS2812. In armbianEnv.txt I prescribe overlays:
  1. overlays=analog-codec spi-spidev
  2. param_spidev_spi_bus=1
Copy code
The device appears in /dev:
  1. ls -l /dev/*spi*
  2. crw------- 1 root root 153, 0 мар 21 11:57 /dev/spidev1.0
Copy code
However, SPI doesn't work (I'm testing with python - py-spidev and a test script). With the same configuration on Orange Pi Zero (H3) everything works fine!

Can you tell me what could be wrong and how can I find the problem?
