Hi @caoliuchao, 我觉得{}位置没错，下面是我的看法：
if (on_thread_before_fault)是为了切换到psp stack, 如果按照你的修改，能走到else case，那就意味着发生hardfault之前是handler mode, 此时没有必要再去检查是否为psp stack。- 如果没有发生hardfault，
cm_backtrace_call_stack默认使用msp，但当前可能处于handler mode或者thread mode，如果是thread mode，需要切换到psp stack。这就是else case。（如果按照你的修改，即使处于thread mode，还是在用msp stack。)
