U-boot for Banana Pi

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.

Hello,

Hello,

currently memory controller paramaters are set from constants defined in u-boot at compile time. U-boots needs to configure the memory controller so it has some place to load the kernel binary.

If your memory configuration is incorrect you might have stability
problems or may not be able to access all memory. There is a10-meminfo
tool http://linux-sunxi.org/Retrieving_device_information#Reading_memory_information_from_registers
which you can run on the original Android or GNU/Linux installation
(if any) to determine what memory parameters the manufacturer used and
configure your u-boot accordingly. Note that cubieboard1 and
cubieboard2 use a different SoC so u-boot compiled for one might not
configure the other correctly. Especially the SMP on a20 works
correctly only with recent u-boot. You should use u-boot compiled for
your SoC a10/a20/...

Support for BananaPi is currently available in the u-boot-arm.git tree.

Thank You.
I've downloaded u-boot-arm.git tree yesterday.

Started config menu as for usual kernel:
root at freebsd:/usr/src/u-boot-arm # gmake -j4 ARCH=arm CROSS_COMPILE=arm-eabi- HOSTCC=cc USE_PRIVATE_LIBGCC=yes menuconfig

Then selected:
- ARM architecture
- Target select: support sun7i
Not selected:
- SPL (due compilation errors, see below)

Compilation:

Maybe not this way??

It also fails with:
root at freebsd:/usr/src/u-boot-arm # gmake -j4 CROSS_COMPILE=arm-eabi- USE_PRIVATE_LIBGCC=yes Bananapi_defconfig
root at freebsd:/usr/src/u-boot-arm # gmake -j4 CROSS_COMPILE=arm-eabi- USE_PRIVATE_LIBGCC=yes
as README file says, with the same error:

scripts/Makefile.build:55: /usr/src/u-boot-arm/board/amd/sunxi/Makefile:
No such file or directory
gmake[1]: *** No rule to make target `/usr/src/u-boot-arm/board/amd/sunxi/Makefile'. Stop.

I'm running FreeBSD 10.0 64-bit VM to build my images..

Hello again,

successfully compiled U-boot-arm.git source under bare-metal Linux on Banana Pi itself (not FreeBSD 64-bit VM).
But still getting troubles at:

Yes, I know I should type here:
fatload mmc 0 0x40200000 kernel; go 0x40200100
to load my FreeBSD 10.x kernel, however my serial console over J11 is read-only..

The only thing I don't uderstand why new loader ignores my boot.scr file? Tried FAT16, FAT32..

To be clear:
#U-boot loader writing to image
dd if=/root/banana/u-boot-arm_git/u-boot-sunxi-with-spl.bin conv=notrunc of=banana.img bs=1024 seek=8
#mkimage tools used from Lemaker's git
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
#but the same result for u-boot-arm.git tool
