每次在STM32CubeMX生成Keil5的代码，用Keil5打开后，编译过程中报错：
../Drivers/STM32F1xx_HAL_Driver/Src/stm32f1xx_hal_pwr.c(137): error:  #1113: Inline assembler not permitted when generating Thumb code

具体错误在：
/* Private functions ---------------------------------------------------------*/
__NOINLINE
static void PWR_OverloadWfe(void)
{
  __asm volatile( "wfe" );
  __asm volatile( "nop" );
}
当我将这2行注释掉后，系统能够从新编译，并能够正常运行！

请问：
1、这2句是什么意思，注释掉会不会有问题？(本人新人一个，还望大神详细解释)
2、有没有办法或哪里设置，将这里处理掉？

我的没有遇到过这种问题，请问你怎么配置的。可以穿一下配置文件

我是在STM32CubeMX中生成的项目程序，使用STM32F103C8T8芯片，配合使用Firmware 1.3.1，Keil系统使用的是uVision V5.11，配的是对应编程模块。无论我陪什么样的设置，都提示这个错误，只有注释掉这2句，就能够使用！
附上原始生成的代码

汇编指令，
WFI(Wait for interrupt)和WFE(Wait for event)是两个让ARM核进入low-power standby模式的指令，由ARM architecture定义，由ARM core实现。
NOP 就是空指令。
