How to enable SPI2 on A20 Olinuxino LIME


Recommended Posts

Armbianmonitor:

Hi All,

I'm trying to enable SPI2 on a A20 Olinuxino LIME board.

I found an old post on this forum regarding LIME2, so I try the same and in armbianEnv.txt I add the lines:

 

overlays=spi2 spi-spidev

param_spidev_spi_bus=2

param_spi2_bus_pins=b

 

At reboot, the message:

Failed to load '/boot/dtb/overlay/sun7i-a20-spi2.dtbo'

 

I think because the file is not found

 

Only SPI0 is active

 

How can I enable SPI2 ?

 

Thanks in advance

PaoloC
