海灣合作委員會 - 部分有錯LMA

Question

我遇到了我的鏈接腳本的問題。 .data2，.nonsharedram和.bss部分具有錯誤的LMA。它們應該放在FLASH中，而是放置在SHARED1和SHARED2區域中。

鏈接腳本：

MEMORY 
{ 
    FLASH  : org = 0x100000, len = 1M 
    NON_SHARED : org =  0x100, len = 0x4600 
    STACK  : org = 0x4700, len = 0x900 
    BOOTPROG : org = 0x8080, len = 0x1D80 
    SHARED1 : org = 0x10000, len = 0x3000 
    SHARED2 : org = 0x18000, len = 0x4000 
    LATCH  : org = 0x40000, len = 2 
    DSPCODE : org = 0x1030000, len = 0x4000 
    EXTRAM  : org = 0x200000, len = 1M 
}

Answer 1

發現我應該使用：

AT (LOADADDR (.nonsharedram) + SIZEOF (.nonsharedram)) 

而不是

AT (ADDR (.nonsharedram) + SIZEOF (.nonsharedram))
