Hello Furkan,

You can find all build instructions in the lfs/ directory.

For the kernel there is lfs/linux and there is lfs/u-boot.

Configuration files for the kernel are in config/kernel.

Best,

Hello Furkan,

*please* copy the list. I can’t have a conversation in private only with you. This conversation should be shared with other and documented, too.

We have not ported the configuration and all the patches that we need, yet.

> I will try to reuse your kernel5.9 pkg of x86 and try to build the same for arm boards as I have all the config needed. 

This is not a good idea, because the kernels are slightly different.

> I have been compiling kernels for arm board since 5.0 and maintaining kernel support so I hope I can do the same for ipfire soon. The only thing I might miss is the additional config needed for ipfire which we will come to later once I get the kernel to boot work 5.9.

Exactly, if you just need a kernel that compiles, that is not very difficult to achieve. But we have a custom configuration and we have some patches that make that kernel work better for us. Those need to be tested a lot before we can release them.

> I will try to get it to boot and support you with ARM as I am aware arm is now in your priority list and its not easy to maintain but trust me it will be easily once we have a working image for decent and powerful boards. 

That would be great. I personally do not have any ARM hardware that I use for development any more, but since there is interest in the community to support IPFire on as much hardware as possible, I would support this.

> Thanks for replying.  I will start looking into what I can do with my limited knowledge of ipfire source;) 

Please ask questions. Development is not a quick job. It requires planning, a lot of work and testing.

It is not enough if a device just boots. It has to work. All of it. That includes networking, power management, LEDs, etc. And it needs to perform. There is no point to support hardware for the fun of it. If people cannot use this in production and they cannot rely on things working after the next update it is worthless to spend time on getting it to work in the first place.

Best,

Hello,

Again, *please* copy the list.

We currently do not have an ARM version of that kernel available. There is only a version for x86.

As soon as we have a kernel that boots it will be announced on the development list. So, please watch this space :)

We currently have a version of kernel 5.9 that we are testing and we will target to move to 5.10 as soon as it comes out.

I hope for a release early next year.

Hello Furkan,

Thanks for signing up and posting :)

I suppose we are talking about ARM64:

We currently only support systems that use EFI. If there is an EFI BIOS, it will launch GRUB and hopefully return all required configuration to the kernel.

Do you have any output from the bootloader/kernel?

No, we only support a generic way to boot, because it is simply not feasible for us to provide hundreds of different images for all ARM boards out there.

> Where can I find the source code for the boot script package?  

https://git.ipfire.org/?p=ipfire-2.x.git;a=blob;f=lfs/grub;h=811c2f745e267e5ff6c246b66bc5f2196e12b780;hb=HEAD

This is how we install GRUB on x86 and ARM64.
