Hi, Albert:

I have ever tried to del these code in crt0.S :
ldr sp, [r8, #GD_START_ADDR_SP] /* r8 =
gd->start_addr_sp */
bic sp, sp, #7 /* 8-byte alignment for ABI compliance
*/
ldr r8, [r8, #GD_BD] /* r8 = gd->bd */
sub r8, r8, #GD_SIZE /* new GD is below bd */
/// tricky code : insure to return here after running
relocate_code.
adr lr, here
ldr r0, [r8, #GD_RELOC_OFF] /* lr =
gd->start_addr_sp */
add lr, lr, r0
ldr r0, [r8, #GD_RELOCADDR] /* r0 = gd->relocaddr */
/// start.S implement this function.
b relocate_code
Then no relocation, it seemed OK.
Best wishes,
