Finally, I got it. PI20 used as 1-wire pin, so uart7 (serial@01c29c00) is disabled. On Banana Pro expansion connector it's pin 32 (UART7_TX). Configured pin # cat /sys/kernel/debug/pinctrl/1c20800.pinctrl/pinmux-pins | grep PI20 pin 276 (PI20): onewire_device 1c20800.pinctrl:276 function gpio_in group PI20

Thank you Igor, but decompiled .dts file is slightly different than expected. Can't find label &pio in decompiled one. So I tried modify [u-boot.git] / arch / arm / dts / sun7i-a20-bananapro.dts and built u-boot. Banana don't boot with this .dtb file.

How to enable 1-wire in device tree? I know http://linux-sunxi.org/1-Wirebut don't have .dts file for Banana Pro.

It's working, thanks.

While searching for solution, I've changed ext4load mmc 0 0x49000000 /boot/dtb/sun7i-a20-bananapro.dtb in /boot/boot.cmd But seems, You provided working solution for now.

I had another issue with SATA on Banana Pro, Armbian 5.0, kernel 4.4.1. [ 3.447472] ahci-sunxi 1c18000.sata: PHY power up failed. [ 3.447540] ahci-sunxi: probe of 1c18000.sata failed with error -5 Found the same problem here http://forum.armbian.com/index.php/topic/643-no-sata-on-fresh-compile/ But patch didn't helped me. I've hardcoded power up for SATA in u-boot for Banana Pro board, recompiled and now it's working. I'm new here, so I've chosen bananapi in "Choose a board" dialog. Is it correct for Banana Pro?
