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: Keyring file not available at /usr/share/keyrings/debian-archive-keyring.gpg; switching to https mirror https://deb.debian.org/debian I: Installing core packages...
