enable SPI0 fail (armbian - Bananapi Zero M2 - proc: H3)

[Bruno POULTIER]

Hi all,

 

SPI has been enabled into /boot/armbianEnv.txt with:

overlays=spi-spidev
param_spidev_spi_bus=0

 

Nothing works knowing that the wiring between device and BPI has been checked more than 3 time.

 

How can I check that SPI0 works well? where can I check that dtd file is correctly loaded? What are created files on fs when the spi port is correctly enabled?

 

==> Armbian 21.05.1 Focal with Linux 5.15.48-sunxi

 

Many thanks

[Myron]

Hello Bruno,

 

I don't have any BPI boards, but in addition to Myron's request to understand specifics.

 

What is the output ?

demsg | grep spi*

 

armbianEnv selections look correct, but will require more info.
