Subject: [U-Boot-Users] BSS initialization wrong on ARM??
Date: Tue, 4 May 2004 11:12:56 +0200 [thread overview]
Message-ID: <200405041112.56047.maillist@fsforth.de> (raw)
Hi folks,
on the smdk2410 I found out that the BSS segment is initialized at offset 0x4
and not with offset 0x0, leaving the first entry undefined (in my case
timer_load_val), at least with gcc-3.3. Cause of pain is
arm920t/start.S:clear_bss
clear_bss:
ldr r0, _bss_start /* find start of bss segment */
add r0, r0, #4 /* start at first byte of bss */
ldr r1, _bss_end /* stop here */
I think the add has to be removed. This also seems to be the case on arm720t
and arm926ejs.
Bye,
