Hi sir,
we got some problem that need your kindly help :
Cpu Type:LS1043
The orignal codes is so complicated ,so I simple the issue like this:
1.Firstly,I have a global array which address is:0x9e473158,
int g_port_list[] = {1,2,3,4,5,6};
2.Secondly,I have one struct like this:
typedef struct chip_type
{
int port_num;
int *port_list;
}chip_type_s;
3.Thirdly,I declared one struct varilable as below:
chip_type_s g_my_chip =
{
.port_num = 6,
.port_list = g_port_list,
};
4. Here is the issue,I have a pointer:
int *port_list;
port_list = g_my_chip.port_list ------ which the value of port_list should be 0x9e473158,But after I print it out,I got the value 0x73158,and I found the value g_my_chip.port_list is 0x73158 too,Could you please help to point why the address was cut to the least 20 bits ??
BTW:
This is cross compile and compile flags :
cross compile: aarch64-fsl-linux-gcc
compile flags: -DCONFIG_ARM -DCONFIG_ARM64 -D__ARM64__ -march=armv8-a -fno-common -ffixed-x18 -fno-pic -mstrict-align -ffunction-sections -fdata-sections -fno-builtin -ffreestanding -nostdinc -pipe -Wno-builtin-macro-redefined -fno- stack-protector -Wno-format-nonliteral -Wno-format-security -DSTANDALONE -O2 -Os -Wstrict-prototypes -fno-pic -Wall -DTEXT_BASE=0x9e400000
