XC32链接器错误，用于尝试在绝对地址上分配持久数据

IDE版本：MPLA4.0编译器XC32 GCC版本V1.44背景信息/上下文：我的Bootloader应用程序在一个绝对RAM地址中使用一个持久的数据标志，“BootSuMeDEYStand”，这是由引导加载程序和运行时程序已知的，当运行时应用程序被触发接受固件升级时，将分配一个唯一的标志值，然后做一个软盘（），其中引导装载器将读取标志值并进入固件升级模式。因此，我需要指示编译器和链接器允许绝对地址和持久内存属性。158提供以下示例，用于在绝对地址指定命名数据区段：INTO FO AyAtditTyx（（节（MyStage）），地址（0xA000）），此外，编译器指南显示在第34页上，如何用下面的例子分配持久数据：int TBUDX x属性表最后，XC32汇编程序、链接器和实用工具用户指南在第59页上标识了持久数据对象的节名“坚持”，并且自定义链接器脚本的持久部分如下：.Currase:{ItasyListDe=；.*（.Currest.Actult.*）*（.PBSS.PBSS.*）= AlcIn（4）；yTrimeEngult=；} & kSG1L1DATA.MeSO，我将所有上述信息应用到我的单个持久数据项UIT32 BooToMoDeIOM状态中，在定义为0xA000 00 4的持久数据区域中，大小为4字节，正好适合我的数据，如下：在我的自定义链接器脚本中：+＝4；*（.Currest.Actult.*）*（.PBSS.PBSS.*）。=对齐（4）；有人能对此提出建议/见解/建议吗？谢谢，马卡姆



      以下为原文

    IDE version: MPLAB 4.0
Compiler xc32-gcc version v1.44

Background Info/Context:
My bootloader app is using a persistent data flag, 'boot_mode_status' in an absolute RAM address, known by both the bootloader and the run time program, that when the run time app is triggered to accept a firmware upgrade, will assign a unique flag value and then do a SoftReset(), wherein the bootloader will read the flag value and enter a firmware upgrade mode.

So, I need to instruct the compiler and linker to allow for BOTH an absolute address and persistent memory attributes.
The XC32 Compiler User's Guide, on page 158 provides the following example for designating a named data section at an absolute address:
        int foo __attribute__((section("mysection"),address(0xA0000004)));

Furthermore, the Compiler guide shows on page 34, how to allocate persistent data with the below example:
        int tblIdx __attribute__ ((persistent));

Finally, the XC32 Assembler, Linker and Utilities User's Guide identifies on page 59 the section name, 'persist' for persistent data objects.
And, the Custom Linker script has the persistent section as follows:

.persist :
{
_persist_begin = .;
*(.persist .persist.*)
*(.pbss .pbss.*)
. = ALIGN(4) ;
_persist_end = .;
} >kseg1_data_mem

So I applied all of the above information to my single persistent data item, UINT32 boot_mode_status, in the persistent data region I defined to start at 0xA0000004, with a size of 4 bytes, just big enough for my data, as below:
====================================================================
In my custom linker script:
.persist 0xa0000004 :
{
_persist_begin = .;
. += 4;
*(.persist .persist.*)
*(.pbss .pbss.*)
. = ALIGN(4) ;
_persist_end = .;
} >kseg1_data_mem

In my C file:
UINT32 boot_mode_status __attribute__((section(".persist")));
=============================================================
The result, was the below link error,
“Error: Attributes for section '.persist' conflict with implied attributes”


Can anyone lend instruction/insight/advise on this?

Thanks,
