Hi everyone,
currently I am playing with my NanoPi NEO and build an image for it using crochet. The image was able to boot but the network interface could't be attached:
# dmesg | grep awg
awg0: <Allwinner Gigabit Ethernet> mem 0x1c30000-0x1c30103,0x1c00030-0x1c00033 irq 35 on simplebus0
awg0: soft reset timed out
device_attach: awg0 attach returned 60
Since awg0 is running fine with the FreeBSD image linked in the FriendlyARM wiki [1], I tried to swap its U-Boot (2016.07) against mine from the ports (2017.07). With the following patch and the older U-Boot I managed to get awg working:
Index: sys/boot/fdt/dts/arm/h3.dtsi

Sadly my USB network card is not working with older U-Boot:
U-Boot 2017.07
# usbconfig

ugen1.2: <vendor 0x0fe6 USB 2.0 10100M Ethernet Adaptor> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (120mA)
U-Boot 2016.07
# usbconfig
ugen0.1: <Allwinner EHCI root HUB> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (0mA)
ugen1.1: <Generic OHCI root HUB> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (0mA)
For building I used GENERIC kernel and revision 322966.
Does anyone know how to fix the "soft reset timed out" error? I am thankful for every Idea, I will try it out.
