[WIP] Mainline Buildroot

VIM1 Linux Kernel & U-Boot
1

Hello,

I’m trying to port the mainline buildroot on Khadas VIM, and may be in the future be available in the official repository
It automatically generate an minimalist linux image bootable from a SD card.

Linux version : 3.14.29
Uboot : v2015.01

How to :

# git clone https://github.com/thauti/buildroot-kvim

Use the template
# make kvim_defconfig

Customize your image
# make menuconfig

Build
# make

You should have a sdcard.img file in /output/images
Copy the bootable “sdcard.img” into a microSD card:

sudo dd if=output/images/sdcard.img of=/dev/sdX bs=8M

Currently you need to use the serial/uart to get the console.

Status

Working:

  • Bootable

Not tested:

  • Ethernet
  • Wifi

Not working:

  • HDMI/Mali (the framebuffer is available)

Please feel free to test it and contribute

Hi @Ticc0,

Maybe you could use Linux 4.19 and U-boot 2018.11 since they support the Khadas Vim and Khadas Vim2, no ?

Great work.
I am waiting for my vim1 to arrive so i can test it.
Any update on this though?

Would be interested in knowing how you built this so i can try one of my own

I have tested this project, but I have entered in Linux:

Weird, it doesn’t seems to boot anything
Sorry, I have no more enough time to work on the project :confused:

EDIT: Maybe you don’t have uboot tools installed:

sudo apt-get install u-boot-tools

maybe you can check this post

He might be able to help you as he built the kvim1 kernel from mainline kernel
