Where exactly in init are you trying to print? If you're in the

I've written the libc/csu part, kernel successfully starts init and init
forks off for the execve of -sh,

td_retval[0] is the low word, and td_retval[1] is the high word, you
just need to make sure the values from those two words get returned
properly to userland.
1) syscall returns 32-bit value:
r2 = rv[0];
r3 = rv[1];
r3 is irrelevant here (ABI: 32-bit values returned

It sounds like a tty driver problem.
Does the emulator even support this?
Do you have a package, so that people can install your developement

Why does the cast from 32 to 64 treat r3 as the lower 32-bits when
a 64-bit return value treats r3 as the upper 32-bits and r2 as the

problems with either one or the other. I also don't understand
