[Cannot obtain spidevX.Y on BananaPi M1+]

This is the boot log with the most recent version of Armbian, this log is without the fdtfile in the armbianEnv.txt file.

 

Furthermore another try is with the following lines on the armbianEnv.txt and this is the updated log.

[Cannot obtain spidevX.Y on BananaPi M1+]

Hi, I am trying to use the SPI interface on the board GPIOs of a BananaPi M1+. I have started the latest version of Armbian available for this board (Armbian_19.11.6_Bananapi_bionic_current_5.4.8) and after the initial configuration the "/boot/armbianEnv.txt" file has the following added lines:

	fdtfile=sun7i-a20-bananapi-m1-plus.dtb
	overlays=spi-add-cs1 spi-spidev
	param_spidev_spi_bus=0

I have rebooted but I am unable to use the spidevX.Y under the "/dev" folder. What am I missing? 

NOTE: I have tried several combinations of values on the armbianEnv.txt configuration file (ie: using only overlays flags without the other ones, using only the spi-spidev flag, etc...), none succeeded.
