Bootstrapping an Olimex A64-OLinuXino
Hi,
I'm trying to bootstrap an Olimex A64-OLinuXino board from scratch, using
Debian stretch on x86_64 as the build host. So far, I've:
- cross-built mainline U-boot 2018.01 including the SPL and BL31 from latest
https://github.com/apritzel/arm-trusted-firmware.git#allwinner and
a64-olinuxino_defconfig:
(arm-trusted-firmware) $ make PLAT=sun50iw1p1 DEBUG=1 bl31 CROSS_COMPILE=aarch64- linux-gnu-
(u-boot) $ make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- a64-olinuxino_defconfig
(u-boot) $ make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- BL31=$(pwd)/../arm-trusted-firmware/build/sun50iw1p1/debug/bl31.bin
- cross-built mainline kernel 4.15.7
(kernel) $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig
(kernel) $ make -j4 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
- partitioned and installed to SD card following the instructions in
board/sunxi/README.sunxi64
SD card has a 128MB FAT partition (p1) and the remainder as ext4 (p2)
- ran the debootstrap 1st stage:
sudo debootstrap --arch=arm64 --variant=minbase --foreign stretch /mnt
- sucessfully booted into /bin/sh using the following boot.scr:
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10
load mmc 0:1 0x43000000 dtb
load mmc 0:1 0x41000000 Image
booti 0x41000000 - 0x43000000
(no initrd for now since I'm lazy...)
However, while running the debootstrap 2nd stage on the board, it seems that
the kernel is not stable:
# mount -n -o remount,rw /
[ 93.035277] EXT4-fs (mmcblk0p2): re-mounted. Opts: (null)
# /debootstrap/debootstrap --second-stage

I will try with a 4.16-rcX kernel, but on the off chance that someone on
the list has already been through this and can see anything wrong in the
steps I did above or can suggest a known-good recent kernel (including
its configuration), let me know.
