Post subject: | user section出現overlap error |
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. |
