博客围绕Rust和STM32在嵌入式开发中遇到的问题展开。涵盖defmt - test编译异常、单元测试异常、找不到链接脚本、烧录错误以及编译警告等问题，并针对每个问题给出了相应的解决办法，如修改配置文件、注释冲突配置等。

问题答疑 Q&A

defmt-test 编译异常

报错信息

  = note: rust-lld: error: memory.x:4: region 'FLASH' already defined
          >>>   FLASH : ORIGIN = 0x08000000, LENGTH = 64K
          >>>                                         ^

          flip-link: the native linker failed to link the program normally; please check your project configuration and linker scripts

解决方案

在 .cargo/config.toml 文件中包含了两个目标都生效了, 导致 memory.x 被读取了两次。

region ‘FLASH’ already defined

[target.thumbv7m-none-eabi]
# runner = "qemu-system-arm -cpu cortex-m3 -machine lm3s6965evb -nographic -semihosting-config enable=on,target=native -kernel"
# runner = 'arm-none-eabi-gdb'

# 该配置只能写一份, 否则 memory.x 会导致异常
