As well as trying to boot it with the BRP as primary memory (BRP first

With BigramPlus as sole memory the system can't seem to deal with the
initramfs (see log)
However, according to this log you have both enabled:
On node 0 totalpages: 4096
DMA zone: 40 pages used for memmap
DMA zone: 0 pages reserved
DMA zone: 4096 pages, LIFO batch:0
16 MiB
On node 1 totalpages: 65536
DMA zone: 640 pages used for memmap
DMA zone: 0 pages reserved
DMA zone: 65536 pages, LIFO batch:15
256 MiB
SLUB: Unable to allocate memory from node 0
SLUB: Allocating a useless per node structure in order to be able to continue
SLUB: HWalign=16, Order=0-3, MinObjects=0, CPUs=1, Nodes=8
Probably the 16 MiB in the first chunk is too small to allocate
page tables from, especially if it contains the initramfs.
What happens if you put the BRP first in the memfile?
Before chipram?

No, as the first FastRAM chunk.
ChipRAM must always be first ;-)
This one works:

OK, that's what I meant.
Same as only using the bigram (and I got into the OS just fine, but I
had to do the installation through qemu)
Yeah, that won't make much of a difference, as it may take a while
before it actually starts using the on-board RAM.
Does the initramfs start working if you restrict the amount of RAM used,
by adding e.g. mem=16M or mem=64M to the kernel command line?
If there is a limitation on memory size somewhere in the code, that may
help identifying it.
Thanks!
