RZN2L使用backtrace时，栈地址不对问题在使用RZN2L进行backtrace实验时，发现在进入Abort中断后栈顶指针也发生了很大的变化，猜测是因为RZN2L默认运行在SVC模式，而进入Abort后切换到了IRQ模式，导致栈顶地址错误。 RZN2L在system_init函数设置成SVC模式 1234567__asm volatile ( "cpsr_save: \n" " MRS r0, cpsr \n" /* Read original CPSR value to r0 */ " BIC r0, r0, %[bsp_mode_mask] \n" /* Clear the mode bits */ " ORR r0, r0, %[bsp_svc_mode] \n" /* Set value of SVC mode bit ...

cmbacktrace分析分析以瑞萨RZN2L举例，在发生错误时，由于默认情况下RZN2L运行在SVC模式，所以要先切换回SVC模式，栈才对应。 123456789101112131415161718192021void Default_Handler (void){ /** A error has occurred.
