It should be 2025.02.0.
I switched to walnascar and this should be the part used:

That's is very interesting.
What I did not get, yet:
So we can keep our partition scheme, the CPUs bootloader is searching
hardcoded for partition table -> first vfat -> MLO.
Then barebox-am33xx-beaglebone.img is put there as MLO?

 Can this be switched on/off somewere in the yocto framework so the old
 MLO/barebox.bin pair is genereated?
