Hi,

I'm trying to port my company's existing hardware device based on an A13-OLinuXino-WIFI from using the linux-sunxi software stack to using mainline U-Boot and kernel.

I created an image for testing using the following commands:

Code Select
truncate -s4G test.img
dev=$(losetup --show -f "$IMG")
fdisk "${dev}"
=> 64MB Boot
=> 2G root
=> for the rest var
partprobe "${dev}"

in the U-Boot sources (checked out 2016.07)
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- A13-OLinuXino_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
dd if=u-boot-sunxi-with-spl.bin of="${dev}" bs=1k seek=8

mkfs.ext4 "${dev}"p1
mkfs.ext4 "${dev}"p2
mkfs.ext4 "${dev}"p3

mount "${dev}"p2 /mnt/chroot
mkdir -pv /mnt/chroot/var
mount "${dev}"p3 /mnt/chroot/var
qemu-debootstrap --arch=armhf --variant=minbase jessie /mnt/chroot http://ftp.de.debian.org/debian
umount -Rv /mnt/chroot

in the kernel sources (checked out 4.7.1)
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage dtbs
cp -v arch/arm/boot/zImage /mnt/chroot/
cp -v arch/arm/boot/dts/sun5i-a13-olinuxino.dtb /mnt/chroot/
umount /mnt/chroot
losetup -D

dd if=test.img of=/dev/sdc bs=256K

ext4load mmc 0:1 0x46000000 zImage
ext4load mmc 0:1 0x49000000 sun5i-a13-olinuxino.dtb
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10 rootfstype=ext4
bootz 0x46000000 - 0x49000000

For U-Boot I changed the following settings compared to the standard configuration:

Code Select
217c217
< CONFIG_VIDEO_LCD_MODE=""
---
> CONFIG_VIDEO_LCD_MODE="x:800,y:480,depth:18,pclk_khz:33000,le:16,ri:209,up:22,lo:22,hs:30,vs:1,sync:3,vmode:0"
221c221
< CONFIG_VIDEO_LCD_BL_EN=""
---
> CONFIG_VIDEO_LCD_BL_EN="AXP0-1"

For the mainline kernel I did the following adjustments (only listening hardware specific ones):

I also ensured that the following are enabled:
Code Select
CONFIG_SPI=y
CONFIG_SPI_MASTER=y
CONFIG_SPI_SUN4I=y
CONFIG_SPI_SUN6I=y

But unfortunately when I boot the system I don't get any output related to SPI or enc28j60. What could I be missing?

Could it be counterproductive that I chose CONFIG_FIRMWARE_IN_KERNEL=y?

You might do better to ask in a place dedicated to Linux on ARM or even on AW chips - such as linux-sunxi.
