Hi all,

I am facing one issue when executing below progmra on ARM target. The
same program work well on X86 host machine,

When execute on Host(x86). the result are as expected.
[root@localhost naveen]# ./a.out  0000 b 2
/dev/mem opened.
Memory mapped at address 0xb7f00000.
Value at address 0x0 (0xb7f00000): 0x24
Written 0x2; readback 0x2

But when execute on Target:
# ./a.out 0 w 20
/dev/mem opened.
Memory mapped at address 0x40003000.
Value at address 0x0 (0x40003000): 0xEA000006
Written 0x14; readback 0xEA000006
#
The value does not change. any idea ....

Kind regards
