U-Boot for A64 git

[longsleep]

To make clear what Allwinner did to U-Boot I started a Git repository forked from mainline.

See https://github.com/longsleep/u-boot-pine64 

Branch pine64-hacks has applied the BSP changes on top of mainline 2014.07 tag and contains various required backports and fixes for Pine64 on top.

Disk image test releases for Pine64

I publish disk images which combine U-Boot, Kernel with a minimal initrd as base image for Linux distributions and for testing. **These images are for developers** and  are build with my set of Pine64 image building tools from here.

Released images are signed with a detached GPG signature (.asc) signed by my personal key 0x090EF0DB. Get the key and verify that the download is intact and unmodified.

Code:

gpg --keyserver keyserver.ubuntu.com --recv-keys 090EF0DB
gpg --with-fingerprint simpleimage-pine64-*.xz.asc

To update both Kernel an U-Boot to the latest releases, run the following commands (as root):

Code:

bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_uboot.sh)
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_kernel.sh)

and reboot.

Cheers,
Simon

I made good progress. If you want to have a adventure, see https://github.com/longsleep/build-pine64-image and build U-Boot, ATF, Kernel and Initrd yourself. Proprietary parts used as binary blob (due to lack of full source) are boot0 and SCP firmware - everything else is compiled from source.

Full boot log of what you get:
http://paste.ubuntu.com/14966003/



This is work in progress and i will be adding more docs over the next couple of days.

Nice! Thanks for putting these on github.

I have started publishing images:

https://www.stdin.xyz/downloads/people/l...64-images/

Download from there to see what the current status is. I will release and publish new images when there is progress on either U-Boot or Kernel.

To flash the image, try something like this:

Code:

~$ xzcat simpleimage-pine64-20160207-1.xz|pv|sudo dd of=/dev/sdX bs=1M oflag=sync

Replace /dev/sdX with wherever your SDcard is. Check twice,
if you have the wrong device you might overwrite your harddisk.

The folder also contains a full boot log (BOOTLOG.txt) for you to compare with your own testing and a README.txt with some more instructions (Linux only).

Images are signed with a detached GPG signature (.asc) signed by my personal key 0x090EF0DB. Get the key and verify like this:

Code:

gpg --keyserver keyserver.ubuntu.com --recv-keys 090EF0DB
gpg --with-fingerprint simpleimage-pine64-20160207-1.xz.asc

I have been trying to recreate the image and I stumbled on building u-boot (https://github.com/longsleep/u-boot-pine64.git):

Code:

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
  GEN     include/autoconf.mk.dep
In file included from include/linux/compiler.h:40:0,
                 from include/linux/byteorder/little_endian.h:12,

I tried both the Ubuntu gcc for arm, and also the one from Linaro.
On the Internet it suggests to use the gcc4 version of the file. However, there is a preprocessor error when making the change.

What version of the gcc-arm-linux-gnueabihf toolchain is that? I use gcc-arm-linux-gnueabihf 4:4.8.2-1 as in the Ubuntu repository (on trusty). So you should try with 4.8 as well and i guess it will work. Let me know.

Update: I see now that i should add some details about the toolchains. For U-Boot and ATF use gcc-arm-linux-gnueabihf 4.8. For Kernel and Busybox use gcc-aarch64-linux-gnu 5.2. Kernel and Busybox might work with older version as well, but i did not test. You cannot compile U-Boot with anything newer than 4.8. I will add details to the docs asap.

I built ATF using 
http://releases.linaro.org/14.07/compone...nux.tar.xz as mentioned here: https://github.com/apritzel/arm-trusted-...r-guide.md.

uboot built fine with arm-linux-gnueabihf gcc version 4.7.3 on ubuntu 14.04.3 using the standard apt-get package gcc-4.7-arm-linux-gnueabihf

Haven't been able to test it yet, as I'm downloading the insufferable lichee BSP.

Any possibility you could upload the three BSP files needed by u-boot-postprocess.sh?

I used gcc 5.2.1 (arm-linux-gnueabihf-gcc-5 (Ubuntu 5.2.1-22ubuntu1) 5.2.1 20151010).
I now switched to gcc-4.8-arm-linux-gnueabihf and trying now again.

For the selected compiler to work, it needs a symlink or better use update-alternatives. This is because the compiler has a "-4" appended to the name which messed up cross-compiling.

Yeah i guess i can. In fact i just did. Pull and check the blobs folder - The scripts have been updated to use the stuff from there. It is no longer required to get the Lichee.

The instructions habe been updated and they now support building images based on the BSP Kernel which has  working MMC, USB and Ethernet drivers.

Similar to the U-Boot Tree, i now also have a Kernel Tree based on the Linux sources in the BSP at https://github.com/longsleep/linux-pine6...ne64-hacks - it is up to you which Kernel you experiment with.
