In . . ./crochet/board/BananaPi-M3/overlay/etc/ there should be:
# ls
fstab rc.conf rc.d
When things work right these are simply copied.
If one of these files was not copied over then it may be that
some other(s) were not copied over as well.

awg Ethernet support was added about 2 months before head
-r304406 was turned into stable/11 -r304408 based on the
svn history: Ethernet added for A83T back on 2016-May-4
( -r299084 ).

While I do not know anything about the details I can find the
source code for the "soft reset timed out":
1122 static int
1123 awg_reset(device_t dev)
1124 {
1125 struct awg_softc *sc;
1126 int retry;
1127=09
1128 sc =3D device_get_softc(dev);
1129=09
1130 /* Soft reset all registers and logic */
1131 WR4(sc, EMAC_BASIC_CTL_1, BASIC_CTL_SOFT_RST);
1132=09
1133 /* Wait for soft reset bit to self-clear */
1134 for (retry =3D SOFT_RST_RETRY; retry > 0; retry--) {
1135 if ((RD4(sc, EMAC_BASIC_CTL_1) & =
BASIC_CTL_SOFT_RST) =3D=3D 0)
1136 break;
1137 DELAY(10);
1138 }
1139 if (retry =3D=3D 0) {
1140 device_printf(dev, "soft reset timed out\n");
1141 #ifdef AWG_DEBUG
1142 awg_dump_regs(dev);
1143 #endif
1144 return (ETIMEDOUT);
1145 }
1146=09
1147 return (0);
1148 }
I'd guess that the message indicates a hardware problem.
As I've suggested before: you could see of an official
Linux also fails to initialize the Ethernet interface.
Once checked:
A) If Linux did fail as well then blame the hardware.
B) If Linux worked then get the FreeBSD folks that work
on the A83T/ALLWINNER support to look into the issue.
My guess is the that FreeBSD folks would want a build
with that AWG_DEBUG enabled and information from the
"dump" that it makes if Linux worked.
