在代码中引用放置在 RAM 中的部分，导致链接器错误 [Lc036]

如何解决在代码中引用放置在 RAM 中的部分，导致链接器错误 [Lc036]

STM8，IAR 编译器。

我正在尝试将可变中断向量表 (IVT) 放在 RAM（ram_ivt_section 或 RAM_IVT）中，从 0x00 地址开始。

先决条件：硬件入口点（base_ivt_section 或 IVT_TO_RAM 块）已被替换并重定向到此 RAM 地址。

Header.h ===========================================
#define MCU_INTERRUPT_VECTORS_COUNT     (32)

typedef void (__interrupt *interrupt_handler_t)(void);

typedef struct {
    int8_t value;
    int8_t unused_byte;
    interrupt_handler_t handler;
}interrupt_vector_t;

extern interrupt_vector_t ram_ivt[MCU_INTERRUPT_VECTORS_COUNT];

Source.c ===========================================
#include "header.h"

extern void __iar_program_start(void);
extern void __iar_unhandled_exception(void);

__interrupt void CallUnhandledException(void) { __iar_unhandled_exception(); }
__interrupt void CallResetHandler(void) { __iar_program_start(); }

interrupt_vector_t ram_ivt[MCU_INTERRUPT_VECTORS_COUNT] @".ram_ivt_sector" = {
    {0x82,0x00,CallResetHandler},{0x82,CallUnhandledException},... repeats 32 times.

 Main.c ===========================================
#include "header.h"

int main( void ) {
    __enable_interrupt();
    __trap();
}

它工作正常。在陷阱中，程序陷入未处理的异常。但是，当我尝试修改或读取表格时

Main.c ===========================================
    #include "header.h"

    int main( void ) {

    volatile void* a = &ram_ivt[1].handler;
    // Or
    ram_ivt[1].handler = 0;

    __enable_interrupt();
    __trap();
}

项目在链接器阶段停止构建并出现错误：

Error[Lc036]: no block or place matches the pattern "rw data section .ram_ivt_sector in ram_ivt.o symbols: [ram_ivt]"

解决方法

那是语法错误 interrupt_vector_t ram_ivt[MCU_INTERRUPT_VECTORS_COUNT] @".ram_ivt_sector" ram_ivt_sector 必须是 ram_ivt_section

谢谢@KoynovStas。
