This would be an explanation. But the stack doesn't seem to be part of BSS: _sbss = 0x20003758 ;; Start of bss _ebss = 0x20012b48 ;; End of BSS _susrstack = 0x20012b48 ;; Start of user stack (not used in this application) _eusrstack = 0x20013b48 ;; End of user stack (not used in this application) SP = 0x20017d20 ;; Value of stack pointer when memset() is entered _estack = 0x20018000 ;; Initial stack pointer So I don't see anything that might be wrong here. -- Josef Wolf jw@xxxxxxxxxxxxx
