Dear Experts

We have hikey boards and we building the ARM 64 and 32 debian toolchain on ububtu 16.0.4 pc. Please can you help me if I can get help getting the relevant toolchain to build the same.

 

Thank you in advance

Our build system downloads most used compilers but to tell you which exactly is appropriate for Hikey board u-boot/kernel sources ... no idea. You can try to play around this way:
1. Define a board config https://github.com/armbian/build/tree/development/config/boards

2. Define a source config https://github.com/armbian/build/tree/development/config/sources

 

Check this example for RK3328 ... https://github.com/armbian/build/blob/development/config/sources/rk3328.conf#L32-L43

default branch, kernel 4.4.y need to have a version higher or equal than 6.3  KERNEL_USE_GCC='> 6.3'  while kernel dev branch 4.17.y needs KERNEL_USE_GCC='> 7.0' ... u-boot and atf have their own settings. We know that This board is aarch64 (https://github.com/armbian/build/blob/development/config/sources/rk3328.conf#L1) and this way systems knows which compiler to choose. 

Sometimes trial and error is the fastest way.  We use those:

	done

 

I hope you will find those hints useful.

Thank you Igor

I will give it a try, the requirement is to create Image with least minimum packages only meant for gcc, gdb, glibc and binutils.

 

Thanks a lot

You have to boot the board first. Usually, it's not just kernel and u-boot, but up to few other (pre)loaders. Packages optimization is a fairly simple task. If our default package base is a too much, use PACKAGE_LIST_RM parameter when building an image to remove what you might not need.
