PIC24写闪存限制

你好，我想在Flash地址X0xC00中设置一个标志。在启动之前，我从BooDouther-main中运行这个代码，它工作。Bootloader占用内存的前2页，页3被保留为状态标志。后来从我的应用程序运行，从地址0x1000到以后，如果我运行相同的代码，Flash地址没有被正确地写入。所以PIC24可以写入到T以外的闪存位置吗？在链接器脚本中定义了程序空间？我使用的是PIC24FJ128GB202

    Hello,

I am trying to set a flag in flash at address 0x00C00. From my bootloaders main before anything starts I run this code and it works. The bootloader takes the first 2 pages of memory and page 3 is reserved for status flags.
// Write the new launching flag to memory.
        NVMCON = 0x4003;

        uint16_t dataL = 0x01; //lint !e9034 !e712
        uint16_t dataH = 0xFFFFU;
        
        __builtin_tblwtl(0xBD2C, dataL); //Write the low word to the latch i
        __builtin_tblwth(0xBD2C, dataH); //Write the high word to the latch (8 bits of data + 8 bits of "phantom data") i+1
        
        disable_interrupts();

        __builtin_write_NVM();
        while(NVMCONbits.WR == 1U){}

        NVMCONbits.WREN = 0;
        
        enable_interrupts();

Later from my application which runs from addresses 0x1000 to much later, if I run the same code the flash address is not properly written to.

So can a PIC24 write to a flash memory location that is outside of the program space defined in its linker script?
I am using a PIC24FJ128GB202
