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: U-Boot SPL 2018.05-armbian (Jan 09 2019 - 16:25:26 +0100) DRAM: 1024 MiB CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 Trying to boot from MMC1 U-Boot 2018.05-armbian (Jan 09 2019 - 16:25:26 +0100) Allwinner Technology CPU: Allwinner A20 (SUN7I) Model: LeMaker Banana Pi I2C: ready DRAM: 1 GiB MMC: SUNXI SD/MMC: 0 Loading Environment from EXT4... ** File not found /boot/boot.env ** ** Unable to read "/boot/boot.env" from mmc0:1 ** Failed (-5) Setting up a 720x576i composite-pal console (overscan 32x20) Error: no valid bmp image at 66000000 In: serial Out: vga Err: vga SCSI: SATA link 0 timeout.

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
