Spi Problem On Olimex Lime 2

Recommended Posts

Hi

I' am trying to use the SPI device on the Olimex Lime 2 board but i am having a lot of trouble.

Basicaly i do not see the spidev on the device three.

i am using the last image (Armbian_5.91_Lime2_Debian_buster_next_4.19.59), i have activated the overlays and that is the my armbianEnv.txt file

 

verbosity=1
logo=disabled
console=both
disp_mode=1920x1080p60
overlay_prefix=sun7i-a20
rootdev=UUID=3563b9df-bd15-4366-b897-da0963dfd5a0
rootfstype=ext4
overlays=spi-spidev
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

 

Where am i  wrong?

Thanks in advance for any kind of help

"spi-spidev" overlay requires additional parameters : "param_spidev_spi_bus" and optionally "param_spidev_spi_cs".

For more details, look at /boot/dtb/overlay/README.sun7i-a20-overlays ...
