Banana Pi M1 SPI

[PavloPonomarov]

Hello. I have a problem with SPI interface

I already tried to compile SPI interface as module in kernel config and then to turn it on, but what I get is:

root@bananapi:~# modprobe -v spidev
insmod /lib/modules/4.13.4-sunxi/kernel/drivers/spi/spidev.ko 
root@bananapi:~# lsmod | grep spidev
spidev                 16384  0 
root@bananapi:~# dmesg | grep spidev
*nothing*
root@bananapi:~# ls /sys/class/spi_master/
spi32766

I found a topic about enabling SPI on Banana Pi Pro here. But after repeating same steps(I mean decompiling dtb, adding spidev and compiling it back) for Banana Pi M1 it doesn't boot any more. After U-boot the cursor blinks for about 10 seconds and the only message is "reboot: rebooting system"

One small thing to clarify. In that article there is "/boot/dtb". Does that mean that changes should be made on running board or it means "build/cache/sources/.../arch/arm/boot/dts" on PC where I compile?

Changes are on the board - on most recent (beta) images all is done from within armbian-config.

i updated with armbian-config to newest nightly and enabled all spi overlays but still have no /dev/spi*

any clue?
