Khadas VIM3L uses the same board layout as VIM3, but with an S905D3 chip instead of A311D. Board config is derived from khadas-vim3_defconfig and sei610_defconfig. README is based on README.khadas-vim3; the difference is that VIM3L uses FIP files from the g12a folder in vendor sources not the g12b folder.

|
|
|
u-boot compilation
|
|
==================
|
|
|
|
> export ARCH=arm
|
|
> export CROSS_COMPILE=aarch64-none-elf-
|
|
> make khadas-vim3l_defconfig
|
|
> make
|
|
|
|
Image creation
|
|
==============
|
|
|
|
Amlogic doesn't provide sources for the firmware and for tools needed
|
|
to create the bootloader image, so it is necessary to obtain them from
|
|
the git tree published by the board vendor:
|
|
|
|
> wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

$DIR
|
|
|

> cd vim3l-u-boot
|
|
