[L476RG]could not assign flash memory address to functions for the purpose of upgrade firmware

In the firmware we have some upgrade functions/data, if we want to update the firmware, we have to make sure those upgrade functions/data will not be erased . So I edit Debug_STM32L476RG_FLASH.ld file, and change

FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K
 RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 96K
 RAM2 (rw) : ORIGIN = 0x10000000, LENGTH = 32K
 MEMORY_B1 (rx) : ORIGIN = 0x60000000, LENGTH = 0K

to

FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 768K
 UPGRADE_VAR (rx) : ORIGIN = 0x080C0000, LENGTH = 128K 
 UPGRADE_FUN (rx): ORIGIN = 0x080E0000, LENGTH = 128K 
 RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 96K
 RAM2 (rw) : ORIGIN = 0x10000000, LENGTH = 32K
 MEMORY_B1 (rx) : ORIGIN = 0x60000000, LENGTH = 0K

, I just inserted two memory regions for the upgrade use.

then I also added the following sections in this file.

.crc_table :
 {
 PROVIDE_HIDDEN (__crc_table_start = .);
 KEEP (*(SORT(.crc_table.*)))
 KEEP (*(.crc_table*))
 PROVIDE_HIDDEN (__crc_table_end = .);
 } >UPGRADE_VAR
 
 
 .upgrade :
 {
 PROVIDE_HIDDEN (__upgrade_start = .);
 KEEP (*(SORT(.upgrade.*)))
 KEEP (*(.upgrade*))
 PROVIDE_HIDDEN (__upgrade_end = .);
 
 } > UPGRADE_FUN

also, in my firmware I added attribute for this flash memory distribution:

__attribute__((section(".crc_table"))) static const unsigned int crctable[]={
...
}
__attribute__((section(".upgrade"))) unsigned int crc_cal(unsigned int msg[],int len){
...
}
__attribute__((section(".upgrade"))) short upgrade_firmware(__uint8_t *input){
...
}

Now the problem is: the build on Atollic TrueStudio is succesfull: please see the following build analyzer results

However, when you run the firmware code on TrueStudio, it will show you :

Failure at line:13 in 'Target Software Startup Scripts'. Please edit the debug configuration setting.

I googled and some people mentioned it is a version problem, https://forum.atollic.com/viewtopic.php?t=1382, I downgraded TrueStudio to 9.0.0 tried this but it has "error in initializing st-link device" error.....
