[参考译文] MSPM0C1104：分频期间出现硬故障

器件型号： MSPM0C1104

在我的 MSPM0C1104 部门中、调用_udivsi3 等 GCC 实现时会导致硬故障。  故障最终由闪存中的.word 操作触发、我知道该操作会在其位置分配存储器。

使用 GCC ARM 库时、如何将写入操作放入闪存中？ 更重要的是、如何将它们移至 RAM 中？

  闪存中       (RX) ：origin = 0x00000000、length = 0x00003BFF
  SRAM       (rwx)：origin = 0x20000000、length = 0x00000400
  device_config  (rw！x)：origin = 0x00003C00、length = 0x000001ff
  BCR_CONFIG   (R)  ：origin = 0x41C00000、length = 0x000000FF
