Building MNT Reform RK3588 U-Boot

MNT Reform
1

I’m trying to build U-Boot using the ./build.sh script in Reform / MNT Reform RK3588 U-Boot · GitLab and I’m having trouble. I can’t access the source.mnt.re gitlab (I signed up a long time ago and didn’t get a login), so I am asking here.

Specifically, whenever I run boot_merger, I get the error:

$ ../rkbin/tools/boot_merger ./rock5b-rk3588.ini
-bash: ../rkbin/tools/boot_merger: cannot execute binary file: Exec format error

I think this suggests that the binary was not correctly compiled. Has anyone encountered this before? I am trying to package u-boot for guix in lykso/mnt-reform-nonguix - Codeberg.org, but I’m getting stuck at this step.

I should point out that I am building this on my rk3588 mnt-reform, and I’m hitting this error locally, without guix, using the ./build.sh script. build logs can be found here: ./build.sh stdout - Pastebin.com and the only thing I had to custom install was swig, which I pinned to 4.0.2 (the debian version fails to compile one of the dependencies).

You should be able to git clone everything even without an account. What error do you see?

It is not compiled at all. It is a blob that was committed to git: rkbin/tools/boot_merger at master · rockchip-linux/rkbin · GitHub

And that file turns out to be an x86-64 executable. :frowning:

Maybe you can help improve build.sh with some lines that rebuild the boot_merger tool from source?

Sorry for not being clear – I meant that i couldn’t file an issue on the gitlab repo.
That would make a lot of sense! I don’t think a source exists for rkbin, but I can try to run under qemu and see if it works.

Great! So then I can get past this using qemu-user:

$ sudo apt-get install qemu-user
$ qemu-amd64 ./rkbin/tools/boot_merger
********boot_merger ver 1.35********
	...

Although it looks like I have to define a variant of guix derivation : /

It seems like that’s not possible – I can’t find the source of rkbin and the docs don’t seem to have any build instructions. Let me know if this is wrong! If this is the case, I could add a small modification to the ./build.sh script to preface rkbin commands with qemu, depending on the system architecture.

I tried to sign up for an account on the gitlab instance a while back and I never got verified by an admin. I tried again just now. Happy to contribute the above.
