Where is bss then, if you try to locate it beyond the end of physical
memory? To the best of my understanding there are two  possibilities:
tool  chains  running  on  a  32 bit host will simply wrapr addresses
around, i. e. start placing bss at physical address 0, which  is  not
wrong.  I  don't remember eacty what you get on 64 bit hosts, but the
result is not correct either.


Have you actually tested this code? Didn't you run into such problems?

Best regards,

Wolfgang Denk
