Re: [U-Boot-Users] simple_strtoul overwrites bd_info field

In message 44F54522.4010608@dave-tech.it you wrote:

Check the assembler code (single step it under a debugger).

This is the offending instruction in simple_strtoul: *endp = (char *)cp;

As endp points to one field of the struct bd_info, it gets corrupted. So

Umm.. it should not. endp is the second art when calling simple_strtoul(), and "lib_arm/board.c" passes the address of a local variable here.

the problem is about the pointer "e" in function start_armboot that is passed to simple_strtoul. Any idea?

Did you check which address gets passed to simple_strtoul()? Did you check the generated assembler code as I suggested? [Try "display/i $pc" followed by single-stepping using "si".]
