[参考译文] 链接器错误：不能将 noinit 段与需要初始化的段混合。

您好！

我的团队最近支持了一个有关使用.TI.persistent 段编译代码的客户问题。 在编译器 v15上、该 项目编译为清理。 但是、对于 v21.6.0.0 LTS、它会失败、并显示以下消息：

我相信链接器错误的代码位于两个文件中：

# ctpl_msp430fr2433.c

#if defined(__TI_COMPILER_VERSION__)
#pragma PERSISTENT(ctpl_PORTA_storage)
#elif defined(__IAR_SYSTEMS_ICC__)
__persistent
#endif
uint16_t ctpl_PORTA_storage[CTPL_PORT_INT_STORAGE_LENGTH] = {0};

; ctpl_low_level.asm

; FRAM stack copy
ctpl_stackCopy      .usect ".TI.persistent",CTPL_STACK_SIZE,2

; RAM copy
    .if $defined(CTPL_RAM_SIZE)
ctpl_ramCopy        .usect ".TI.persistent",CTPL_RAM_SIZE,2
    .endif

; Low level state variables
ctpl_mode           .usect ".TI.persistent",2,2
ctpl_state          .usect ".TI.persistent",2,2
ctpl_stackUsage     .usect ".TI.persistent",2,2

链接器消息指出、它不能将.TI.persistent 中的 NOINIT 和非 NOINIT 数据混合在一起(尽管我假设该消息将 PERSISTENT 数据视为 NOINIT)。  

是否可以将.usect 定义的符号标记为 NOINIT？ 或者是否有更好的方法来解决这个问题？
