Building a kernel

#1

gcc-aarch64-linux-gnu does not install using apt, is it in the repo? the u-boot build fails as a result.

I am on the Radxa standard 32 bit Debian image with the Radxa repo enabled and I am trying to follow the instructions for building a Debian kernel.

Hi, Martin

You should build a kernel on PC. Are you trying to build kernel on ROCK Pi 4?

#3

I have the same issue, I realy would like to compile it on the Rockpi.

Mostly becouse cross compiling fail on my mac

Update : I found This Rpisys

Can someone make a defs file for the rockpi?

Thanks

We suggest use docker to build the kernel to have a unified build environment.

You can download the docker for mac from:

https://www.docker.com/products/docker-desktop

We have added the docker file for the building environment:

https://github.com/radxa/rockchip-bsp/tree/master/docker

@jack
My kernel build failed (Debian ARM64), no any detail:

…
CC [M] drivers/net/wireless/rockchip_wlan/rtl8188eu/core/rtw_mp.o
LD [M] drivers/net/wireless/rockchip_wlan/rtl8188eu/8188eu.o
LD drivers/net/wireless/built-in.o
LD drivers/net/built-in.o
LD drivers/built-in.o
MAKE KERNEL IMAGE FAILED.

Is it a known issue or anywhere I can find the building log? Thanks.

#6

drivers/built-in.o doesn’t exist.

#7

The error should be somewhere else, before the log, could you paste the full log on https://paste.ubuntu.com ?

#8

My bad a typo in DTS the kernel was not built correctly, fixed.

#9

Can you elaborate? I am stuck in the same place you were.
