Re: [crosstool-ng/crosstool-ng] bc9ed3: Adds Raspberry Pi 3 sample config

[Mike Ray]

Hello.

I have used this sample to build a toolchain.

However I get 32-bit executables and the '-m64' switch is not recognised.

There is obviously a gap in my knowledge which I can't seem to find an
answer for on Google.

Can I compile a 64-bit executable?  If so, how?

Thanks for any help.

Mike

Sometimes, I expect that when people open pull-requests that they actually test what they submit and I don’t have to do any work.

Today I failed at that. Yeay!

Arm64/aarch64 is kind of a new thing in crosstool-NG, and isn’t well supported.

I took the pull-request for the sample without looking at the specs for the new raspberry pi 3. I had no clue it was 64-bit.

Looks like I will have to take some time and get this going.

Hi Mike,

No, I don’t believe you can - this toolchain is for 32 bit / cortex-a53. You’re looking for aarch64, which I’m also looking into - for the minute this works for RPi3 / raspbian.

Best regards,
Stefan Mulvad

Hi Bryan,

I did test this, but at this time there’s (to my knowledge) no os images available which supports 64 bit. Mine came with 32 bit raspbian,

The chip is capable of running in both 32/64 bit mode - but 64 bit must come down the road as software becomes available.

Best regards,
Stefan Mulvad

Re: [crosstool-ng/crosstool-ng] bc9ed3: Adds Raspberry Pi 3 sample config

[Mike Ray]

Hello.

Good to know it's not just me being an idiot!  I was hoping to use a
toolchain generated with ct-ng to build a 64-bit root file-system using
buildroot or just using the toolchain with cross-LFS.

I will continue to tinker and at the same time wait to see if there are
changes to this sample.

It's true that at the moment there are only 32-bit images available.  I
expect ArchARM to come up with a 64-bit image soon enough though.

Mike

Indeed! That’s the spirit! :)

There may only be one change to the sample, one line added, but the real change will happen in two files (maybe 3). And really, they aren’t big changes.

Indeed, but someone has to push the edge and give it a go?

I need to get myself a PI3. I have to wait till the 15th to order mine, but that doesn’t mean I can’t start getting ct-ng there. I know there are others out there waiting for aarch64 support, so let’s do this.

Well, I feel like I totally missed the mark yesterday. I didn’t realize RPI3 was a 64-bit cpu, and I assumed ct-ng did not have aarch64 support. 0/2…

On the plus side, I have something to test:
https://github.com/crosstool-ng/crosstool-ng/pull/362

Now, the hard part. You can’t run 64-bit binaries on 32-bit.
Also, I’m not sure if you can boot aarch64 from a 32-bit bootloader?
So you may have to start with making u-boot?

I wish I had an RPI3, so I could help with that, but for now I’ll just have to be patient and wait to hear your progress. If you do make progress, and need help, post a git repo somewhere and I’ll try to help if I can.

Re: [crosstool-ng/crosstool-ng] bc9ed3: Adds Raspberry Pi 3 sample config

[Mike Ray]

Hello Bryan.

I'll see if I can tweak the config myself at the same time.  But because
I'm blind I don't find menuconfig (or other curses apps) all that easy
to use.  Incidentally apologies for top-posting but that's another thing
with not being able to see...and a bit lazy.

But there's plenty of ARM Cortex A53 stuff online so I might be able to
just use one of the other configs to hack it.

Mike

I think the toolchain built here should work fine, I’m just saying that the platform itself might need a little love. When I get my rpi3, I’ll definitely be wanting to running the test-suite on it asap.

Re: [crosstool-ng/crosstool-ng] bc9ed3: Adds Raspberry Pi 3 sample config

I think it is not a good idea to have a configuration named after a
board, as the discussion generated around this addition shows.

Indeed, an ARMv8 processor can run both in 32 bits mode or 64 bits mode
depending on the use cases. So a single board like the RPi3 can
require the use of either an ARM toolchain, or an AArch64 toolchain.

So, I think you should stick to configurations for processor cores, not
boards. So:

	arm-cortex-a15
	arm-cortex-a7
	aarch64-cortex-a53
	aarch64-cortex-a72
	...

Then, a RPi3 user can chose either an arm-* toolchain or an aarch64-*
toolchain depending on what he wants to do.

Best regards,

Thomas

I can agree with that. I’ll look into renaming the samples soon!

Cheers,
