我希望自定義user section .dlm,並將dlm section的內容放到DLM中

sag 內容如下:
Code:
USER_SECTIONS .ilm, .dlm

BINARY_PART1 0x00000000 0x00010000
{
   ILM 0x00000000 0x00010000
   {
      VAR _ILM_BASE = 0x00000000 ; ILM base address
      VAR _ILM_SIZE = 0x00010000 ; 64Kb

      LOADADDR __ilm_lmastart
      ADDR __ilm_start
      * (.nds32_init)
      * (.ilm)    ; functions to be put in ILM
      LOADADDR __ilm_lmaend
      ADDR __ilm_end
   }
}
BINARY_PART2 0x00010000 0x00100000
{
   FLASH +0x0
   {
      * (.text) ; program
      * (+RO)     ; const global variables
   }

   SRAM 0x08000000 0x00010000
   {
      LOADADDR __lma_start_data
      ADDR __start_data
      * (+RW)     ; initialized global variables
      ADDR __end_data
      ADDR __start_bss
      * (+ZI)     ; uninitialized global variables
      ADDR __end_bss
      STACK = 0x08010000
   }

   DLM 0x08010000 0x00010000
   {
      VAR _DLM_BASE = 0x08010000 ; DLM base address
      VAR _DLM_SIZE = 0x00010000 ; 64Kb

      LOADADDR __dlm_lmastart
      ADDR __dlm_start
      * (.dlm)    ; data to be put in DLM
      LOADADDR __dlm_lmaend
      ADDR __dlm_end
   }
}


在其中一個source file定義dlm variable
Code:
extern unsigned int TIMER_BASE[4] __attribute__((section(".dlm")));
extern unsigned int PWM_BASE[1] __attribute__((section(".dlm")));
extern unsigned int UART_BASE[2] __attribute__((section(".dlm")));
extern unsigned int SPI_BASE[2] __attribute__((section(".dlm")));
extern unsigned int I2C_BASE[3] __attribute__((section(".dlm")));
extern unsigned int DDC_BASE[3] __attribute__((section(".dlm")));


但在linking時出現錯誤
Code:
section .dlm [00011c14 -> 00011c4f] overlaps section .data1 [00011c14 -> 00011c17]


map.txt內容為
Code:
.dlm            0x08000138       0x3c load address 0x00011c14
.dlm           0x08000138       0x3c ./codebase/main.o
                0x0800014c                UART_BASE
                0x08000168                DDC_BASE
                0x08000148                PWM_BASE
                0x08000138                TIMER_BASE
                0x08000154                SPI_BASE
                0x0800015c                I2C_BASE

.data1          0x08000174        0x4 load address 0x00011c14
*(.data1)
                0x08000178                . = ALIGN (0x8)
*fill*         0x08000174        0x4 00


請問是否sag有那邊寫錯?

Hi Sirs,

請問code中用到的變數很多嗎?若很多的情況下,是否能先將變數減少。

若方便可能將專案寄給我們以便debug.
