  • 与软件包 rt_kprintf_threadsafe 同时使用时,测试时死机
  • 重现步骤:
    • 版本 rt-thread v4.1.1
    • 启用rt_kprintf_threadsafe , CmBacktrace lastest
    • 测试BSP stm32l475-atk-pandora
    • 编译器 GCC v10.2.1
    • 终端运行命令:
msh >cmb_test DIVBYZERO

怀疑与 RT-Thread/rt-thread#6327 是同一个问题

  • 我也遇到了这个情况
  • 我分析了一下,是这样的.
  • cmb软件包中使用rt_enter_critical函数来告诉调度器
  • 但是rt_kprintf_threadsafe 并没有判断这个结果.而是判断了另外两个函数
  • cmb中可以使用rt_interrupt_enter()函数.因为已经进入了错误中断了,等于是进中断函数
