Hi, my overlays=w1-gpio spi-spidev are not working anymore since I upgraded from 4.14.84-sunxi to 4.19.13-sunxi (Banana Pi with armbian 5.70).

Regarding the 1-wire protocol cat /sys/bus/w1/devices/*/w1_slave responds "No such file or directory" since the upgrade.

Also regarding the spi overlay  # ls /dev/spi* should result in  /dev/spidev0.0 whereas kernel 4.19 says "cannot access /dev/spi*: No such file or directory".

All was working fine with the 4.14 kernel.

thanks in advance

What is shown in u-boot log during booting ? Do you see any errors ?

Sorry that it took so long, but serial boot debugging there is misleading info out there, like at http://linux-sunxi.org/LeMaker_Banana_Pi.

In opposite of what is drawn there, I found UART0 wired to J11 (1x2 header). Also the baud rate is 115200 and not 9600 as other sites suggest.

So I also tried to get w1-wire and spi working with kernel 4.19.13 using a new installation (Armbian_5.69_Bananapi_Debian_stretch_next_4.19.13.img) - showing the same results.

 

Here is my boot-output:
