[U-Boot] U-boot for Banana Pi

[TooMeeK Admin]

Hello,

I'm getting some troubles booting FreeBSD on Banana Pi.
I wrote simple script that creates bootable SD card image for FreeBSD OS.

#!/bin/bash
cd /root/banana
rm /root/banana/banana.img
truncate -s 940M banana.img
mdconfig -f banana.img -u0
gpart create -s mbr md0
gpart add -b 1m -s 64m -t fat16 md0
gpart set -a active -i 1 md0
newfs_msdos -F 16 /dev/md0s1
mount_msdosfs /dev/md0s1 /mnt
cp /usr/obj/arm.armv6/usr/src/sys/BANANAPI/kernel /mnt
cd /usr/src/sunxi-tools
echo "fatload mmc 0 0x40200000 kernel; go 0x40200100" > boot.cmd
/usr/src/u-boot-bananapi/tools/mkimage -C none -A arm -T script -d
boot.cmd boot.scr
cp boot.scr /mnt
umount /mnt
mdconfig -d -u0
cd /root/banana
# Original Banana Pi U-boot loader
#dd if=/usr/src/u-boot-sunxi/spl/sunxi-spl.bin conv=notrunc of=banana.img bs=1024 seek=8
#dd if=/usr/src/u-boot-sunxi/u-boot.bin conv=notrunc of=banana.img bs=1024 seek=40
# Lemaker's U-boot loader
dd if=/usr/src/u-boot-bananapi/spl/sunxi-spl.bin conv=notrunc of=banana.img bs=1024 seek=8
dd if=/usr/src/u-boot-bananapi/u-boot.bin conv=notrunc of=banana.img bs=1024 seek=40

The script output:

Original Banana Pi U-boot loader output:

U-Boot SPL 2014.04-10704-gf625d1d (Aug 16 2014 - 23:44:23)
Board: Bananapi
DRAM: 1024 MiB
CPU: 960000000Hz, AXI/AHB/APB: 3/2/2
spl: not an uImage at 1600
spl: not an uImage at 80
### ERROR ### Please RESET the board ###

And Lemaker's:

U-Boot SPL 2014.04-10693-gf954935 (Aug 17 2014 - 21:41:27)
Board: Bananapi
DRAM: 1024 MiB
CPU: 960000000Hz, AXI/AHB/APB: 3/2/2
spl: not an uImage at 1600
spl: not an uImage at 80
### ERROR ### Please RESET the board ###

The only way it works is:
# Cubieboard's 2 U-boot loader from FreeBSD Wiki
dd if=sunxi-spl.bin conv=notrunc of=banana.img bs=1024 seek=8
dd if=u-boot.bin conv=notrunc of=banana.img bs=1024 seek=32

And according to https://github.com/linux-sunxi/u-boot-sunxi/wiki
"If using v2013.07 or earlier then the procedure is slightly different
dd if=spl/sunxi-spl.bin of=/dev/sdX bs=1024 seek=8
dd if=u-boot.bin of=/dev/sdX bs=1024 seek=32"
but I'm using newer version.

I'm getting problems with addressing all available memory (0x40000000, size: 0x40000000 = 1024MB), I belive it's caused by Cubieboard's version of u-boot.
The only way it works is 0x40000000 size 0x20000000 in kernel's memory addressing which is half of all available memory.
So I have to use Cubieboard's 2 version of u-boot to start my board.
