Missing files for Allwinner kernel build

[felix]

Building for Banana Pi currently fails while building kernel with the following:

>>> stage 3.1: building everything
--------------------------------------------------------------
...
cd: /usr/home/felix/src/crochet/work/obj/arm.armv6/usr/home/felix/src/crochet/src/sys/ALLWINNER: No such file or directory
*** [buildkernel] Error code 2

World seems to build fine. My FreeBSD source is on stable/11 branch at 2b54e88 and crochet is at current HEAD of 7feec7a. My config.sh is:

board_setup BananaPi
option ImageSize 1950mb # for 2 Gigabyte card
option Growfs
option CompressImage xz
option User felix
option Ntpd
FREEBSD_SRC=${TOPDIR}/src

The kernel build process first "configures" a kernel by building a directory full of compile information, then changes into that directory where the actual kernel build is performed.

I believe the error you list is saying that it can't find the directory that should have been created by the configure process. What are the contents of

/usr/home/felix/src/crochet/work/obj/arm.armv6/usr/home/felix/src/crochet/src/sys

Were there any earlier errors reported when it tried to configure the kernel?

No previous errors.

I just ran into this problem. It appears to me that the DT source bananapi.dts is broke. When I run DTC I get this: dtc -I dts -O dtb bananapi.dts > /root/bananapi.dtb Error:bananapi.dts:29.1-2 syntax error FATAL ERROR: Unable to parse input tree

I get no such failures with BBB and RPi2 and the DTC I found this by trying to add RTC module DS3231 to RPi2 and BPi. RPi2 sucess, BPi failure.

The bananapi.dts references on line 29

include "sun7i-a20-bananapi.dts

This file does not exsist in the FreeBSD FDT/DTS source folder but does reside in the GNU/DTS source folder. Simply copying it over does not help. It needs fixup for FreeBSD I guess.

dts files have to be pre-processed by cpp, see sys/tools/fdt/make_dtb.sh

[frankharvey]

You are correct and I did build crochet.sh -b BananaPi without any trouble.

This is not an issue with stable/11, which I failed to mention.
