Ah, so it's like that. Great. Is the ELF64 support still not correct? > > I have changed it to 64-bit abi in my Octane kernel, because it won't even > > compile otherwise.

A whopping 16 kilobytes of memory mirrored by the HEART to allow placing exception vectors there (what a weird idea). And you can't remap, I repeat, can't remap anything under 0x20000000 because there are the small Xtalk windows and HEART registers and God only knows what else. Stanislaw Skowronek
