Build Linux kernel for Bubblegum-96

Products Support Bubblegum-96
#1

how to setup the build environment in ubuntu 14.04 x64 environment for Bubblegum-96 Linux
what tool chain and which kernel source can be used?
I found a “kernel from source” from hikey document , can that be used for Bubblegum-96?

#2

Hi Eddy

I’d recommend using a linaro-toolchain (AArch64, little endian). The version shouldn’t matter that much. I use the gcc-4.9 bassed 2015.02 release but that’s only because I’ve been too lazy to upgrade recently.

The vendor kernel can be downloaded via git. Use branch bubblegum96-3.10
from https://github.com/96boards-bubblegum/linux .

To configure and build the kernel:

export ARCH=arm64 export CROSS_COMPILE=aarch64-linux-gnu- make owl_evb_linux_hdmi_defconfig make -j $(nproc)

Installing the kernel will differ depending on whether you are running Android or Debian. I’ve only ever worked with Debian on the Bubblegum-96. In my case I can do the following to install the kernel using ssh:

mkdir -p bubblegum96-root/media/linaro/BOOT cp arch/arm64/boot/Image bubblegum96-root/media/linaro/BOOT cp arch/arm64/boot/dts/s900_96board.dtb bubblegum96-root/media/linaro/BOOT make INSTALL_MOD_PATH="$PWD/bubblegum96-root" modules_install rsync -vax bubblegum96-root/ root@linaro-alip:/

WARNING: If your new kernel doesn’t work, then you will need a 1.8v TTL UART serial adapter and a USB type A to type A cable to debrick the board. You might want to buy these items (which are useful anyway) before trying to install a new kernel.

#3

I have updated the kernel,but it’s not worked.
how to debrick the board?

#4

Hi Eric

There are two levels of recovery possible: recovery after installing a bad kernel (use u-boot to fix this) and recovery after corrupting the bootloader (use the custom debrick tool to fix this).

In both cases the recovery process is similar (full debrick takes longer because it must load u-boot into RAM but the main part of the recovery process is the same).

I think in your case you need to get the board into fastboot mode (see thread below) and run the fastboot commands (steps #8 and #9) from the full debrick documentation.

http://www.96boards.org/forums/topic/fastboot-bubblegum-96/

#5

Forgot to mention… the Bubblegum-96 FAQ contains information on where to find a USB type-A to type-A lead.

#6

Thank you very much!
Successed!
But when installed docker, I found problems.

#7

Hi Eric

To fix those you will have to build and install a kernel. Have you been able to do that after debricking?

#8

Hi danielt
I have followed your steps to build new kernel based on the branch bubblegum96-3.10 at https://github.com/96boards-bubblegum/linux/. And overwrite the Image and modules into /media/linaro/BOOT and / separately. But Linux wont boot (screen black and not able enter desktop UI) after reset.
Please see my logs, how to get a workable kernel source ? and I would like need the kernel with the version > 4.x

#9

Two parts to this. Firstly, you need a relatively recent kernel to run containers, 3.10 is nowhere near the right kernel. So, by default, you can’t use containers on bubblegum.

As for building a kernel, 4.5.0+ builds but I doesn’t appear to boot (I see no output once uboot has transferred control to it. Question - has anybody got a > 4.0 kernel to boot on bubblegum? If so, how?

You can recover from a bricked device if you have a serial link to it. You can run uboot and load the right kernel. You need to know your uboot commands to make this work. It’s probably easier to use the instructions above.

#10

There are no drivers for this board in the 4.5 tree.

#11

Quite so and its quite a jump from v3.10 to v4.5.

The bubblegum96 kernel does contain a couple of backports to allow
systemd to work properly with v3.10 but I couldn’t recommend trying to
backport the container logic.

Forward porting the drivers is a big task but made easier because the
git history for the bubblegum-96 is very clean and many of the drivers
are well written. Nevertheless getting the GPU and WiFi drivers running
would probably require a fair bit of work.
