Hi, barebox as a bootloader,
I wanna know how much ram is needed?
By default configure.
Stack size, malloc area size, etc.

All of this is configurable. Primary this should be kernel
requirements, not barebox. What a arch you want to boot?

I am porting barebox to my router, ar9331 MIPS 24kc 400MHz, 32MB RAM, 4MB Flash.
I don't know what is the proper size to set the stack and malloc.

initcall-> 0x80068168
INITCALL->
initcall-> 0x80063f0c
malloc space: 0x80020000 -> 0x8005ffff (size 2147876864.134217718 EiB)
INITCALL->
initcall-> 0x800640d8
INITCALL->
- - -
Look at the LINE 4, it's strange.

8MiB for malloc space should be fine.

This is indeed strange. size_human_readable takes an unsigned long long
argument, but it is passed an unsigned long argument. It looks like you
have garbage in the upper 32bits. I have no idea what happens there,
this should normally work.

ack, this should normally work. Maybe Kevin could change the type of
msize to 'unsigned long long' and see what happens... but it should work
with unsigned long of course.
